Class DOMWrappingReader

java.lang.Object
  org.codehaus.stax2.ri.dom.DOMWrappingReader

All Implemented Interfaces:

javax.xml.namespace.NamespaceContext, javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader, AttributeInfo, DTDInfo, LocationInfo, TypedXMLStreamReader, Validatable, XMLStreamReader2

public abstract class DOMWrappingReader
extends java.lang.Object
implements XMLStreamReader2, AttributeInfo, DTDInfo, LocationInfo, javax.xml.namespace.NamespaceContext, javax.xml.stream.XMLStreamConstants

This is an adapter class that presents a DOM document as if it was a regular XMLStreamReader. This is mostly useful for inter-operability purposes, and should only be used when the input has to come as a DOM object and the original xml content is not available as a stream.

Note that the implementation is only to be used for use with javax.xml.transform.dom.DOMSource. It can however be used for both full documents, and single element root fragments, depending on what node is passed as the argument.

Some notes regarding missing/incomplete functionality:

• DOM does not seem to have access to information from the XML declaration (although Document node can be viewed as representing it). Consequently, all accessors return no information (version, encoding, standalone).
• No location info is provided, since (you guessed it!) DOM does not provide that info.

getElementAs

public void getElementAs(TypedValueDecoder tvd)
                  throws javax.xml.stream.XMLStreamException

Description copied from interface: TypedXMLStreamReader

Generic decoding method that can be used for efficient decoding of additional types not support natively by the typed stream reader. When method is called, stream reader will collect all textual content of the current element (effectively doing something similar to a call to XMLStreamReader.getElementText(), and then call one of decode methods defined in TypedValueDecoder. The only difference is that passed value will be trimmed: that is, any leading or trailing white space will be removed prior to calling decode method. After the call, passed decoder object will have decoded and stored value (if succesful) or thrown an exception (if not).

The main benefit of using this method (over just getting all content by calling XMLStreamReader.getElementText() is efficiency: the stream reader can efficiently gather all textual content necessary and pass it to the decoder, often avoiding construction of intemediate Strings.

These are the pre- and post-conditions of calling this method:

• Precondition: the current event is START_ELEMENT.
• Postcondition: the current event is the corresponding END_ELEMENT.

Note that caller has to know more specific type of decoder, since the base interface does not specify methods for accessing actual decoded value.

                          throws javax.xml.stream.XMLStreamException

Description copied from interface: TypedXMLStreamReader

Read an element content as an int array. The lexical representation of a int array is defined by the following XML schema type:

    <xs:simpleType name="intArray">
       <xs:list itemType="xs:int"/>
    </xs:simpleType>

whose lexical space is a list of space-separated ints. Whitespace MUST be collapsed according to the whiteSpace facet for the intArray type shown above. An exception is thrown if, after whitespace is collapsed, the resulting sequence of characters is not in the lexical space defined by the intArray data type.

These are the pre and post conditions of calling this method:

• Precondition: the current event is either START_ELEMENT, or a textual event (CHARACTERS, CDATA), or END_ELEMENT (END_ELEMENT is allowed for convenience; if so, no read operation is tried, and -1 is returned immediately
• Postcondition: the current event is the corresponding END_ELEMENT or CHARACTERS if only a portion of the array has been copied thus far.

This method can be called multiple times until the cursor is positioned at the corresponding END_ELEMENT event. Stated differently, after the method is called for the first time, the cursor will move and remain in the CHARACTERS position while there are more bytes available for reading.

Specified by:

readElementAsIntArray in interface TypedXMLStreamReader

Parameters:

value - The array in which to copy the ints.

from - The index in the array from which copying starts.

length - The maximun number of ints to copy. Minimum value is 1; others an IllegalArgumentException is thrown

readElementAsArray

public int readElementAsArray(TypedArrayDecoder tad)
                       throws javax.xml.stream.XMLStreamException

Description copied from interface: TypedXMLStreamReader

Read an element content as an array of tokens. This is done by reader tokenizing textual content by white space, and sending each token to specified decoder for decoding. This is repeated as long as element content has more tokens and decoder can accept more values.

These are the pre- and post-conditions of calling this method:

• Precondition: the current event is either START_ELEMENT, or a textual event (CHARACTERS, CDATA), or END_ELEMENT (END_ELEMENT is allowed for convenience; if so, no read operation is tried, and -1 is returned immediately
• Postcondition: the current event is the corresponding END_ELEMENT or CHARACTERS if only a portion of the array has been copied thus far.

This method can be called multiple times until the cursor is positioned at the corresponding END_ELEMENT event. Stated differently, after the method is called for the first time, the cursor will move and remain in the CHARACTERS position while there are more bytes available for reading.

Note: passed decoder must accept at least one value, reader will not verify capacity before calling it with the first token.

Specified by:

Returns:

Number of elements decoded, or -1 to indicate that there was no more element content tokens to decode.

Throws:

                        throws javax.xml.stream.XMLStreamException

Description copied from interface: TypedXMLStreamReader

Read element content as decoded byte sequence; possibly only reading a fragment of all element content. The lexical representation of a byte array is defined by the XML Schema base64Binary data type. Whitespace MUST be collapsed according to the whiteSpace facet for the XML Schema base64Binary data type. An exception is thrown if content is not in the lexical space defined by the XML Schema base64Binary data type.

Each call will read at least one decoded byte (and no more than the specified maximum length), if there is any content remaining. If none is available and END_ELEMENT is encountered, -1 is returned.

These are the pre and post conditions of calling this method:

• Precondition: the current event is either START_ELEMENT, or a textual event (CHARACTERS, CDATA), or END_ELEMENT (END_ELEMENT is allowed for convenience; if so, no read operation is tried, and -1 is returned immediately
• Postcondition: the current event is the corresponding END_ELEMENT, if all remaining binary content was read, or CHARACTERS if only a portion of the array was read

Additionally, caller MUST start decoding at START_ELEMENT; if the first decode calls is at CHARACTERS or CDATA event, results are not defined: result may be an exception, or invalid data being returned. Implementations are encouraged to throw an exception if possible, to make it easier to figure out the problem.

This method can be called multiple times until the cursor is positioned at the corresponding END_ELEMENT event. Stated differently, after the method is called for the first time, the cursor will move and remain in the CHARACTERS position while there are potentially more bytes available for reading.

Specified by:

readElementAsBinary in interface TypedXMLStreamReader

Parameters:

resultBuffer - Array in which to copy decoded bytes.

offset - Starting offset of the first decoded byte within result buffer

maxLength - Maximun number of bytes to decode with this call

Returns:

The number of bytes actually decoded and returned, if any were available; -1 if there is no more content. If any content was copied, value must be less or equal than maxLength Note that this value is not guaranteed to equal maxLength even if enough content was available; that is, implementations can return shorter sections if they choose to, down to and including returning zero (0) if it was not possible to decode a full base64 triplet (3 output bytes from 4 input characters).

Throws:

javax.xml.stream.XMLStreamException

Method that can be called to get additional information about attributes related to the current start element, as well as related DTD-based information if available. Note that the reader has to currently point to START_ELEMENT; if not, a IllegalStateException will be thrown.

Specified by:

getAttributeInfo in interface XMLStreamReader2

Throws:

javax.xml.stream.XMLStreamException

findAttributeIndex

public int findAttributeIndex(java.lang.String nsURI,
                              java.lang.String localName)

Specified by:

findAttributeIndex in interface AttributeInfo

Returns:

Index of the specified attribute, if the current element has such an attribute (explicit, or one created via default value expansion); -1 if not.

getIdAttributeIndex

public int getIdAttributeIndex()

Description copied from interface: AttributeInfo

Returns the index of the id attribute (attribute with any name, type ID from DTD) of current (start) element, if any. Note that DTD only allows at most one such attribute per element.

Specified by:

getIdAttributeIndex in interface AttributeInfo

Returns:

Index of the ID attribute of current element, if the current element has such an attribute defined; -1 if not.

getNotationAttributeIndex

public int getNotationAttributeIndex()

Description copied from interface: AttributeInfo

Returns the index of the notation attribute (attribute with any name, type NOTATION from DTD) of current (start) element, if any. Note that DTD only allows at most one such attribute per element.

Specified by:

getNotationAttributeIndex in interface AttributeInfo

Returns:

Index of the NOTATION attribute of current element, if the current element has such an attribute defined; -1 if not.

getDTDInfo

public DTDInfo getDTDInfo()
                   throws javax.xml.stream.XMLStreamException

Since this class implements DTDInfo, method can just return this.

Specified by:

getDTDInfo in interface XMLStreamReader2

Returns:

Information object for accessing further DOCTYPE information, iff the reader currently points to DTD event, AND is operating in mode that parses such information (DTD-aware at least, and usually also validating)

Throws:

javax.xml.stream.XMLStreamException

getLocationInfo

public final LocationInfo getLocationInfo()

Location information is always accessible, for this reader.

Specified by:

getLocationInfo in interface XMLStreamReader2

getText

public int getText(java.io.Writer w,
                   boolean preserveContents)
            throws java.io.IOException,
                   javax.xml.stream.XMLStreamException

Method similar to getText(), except that it just uses provided Writer to write all textual content. For further optimization, it may also be allowed to do true pass-through, thus possibly avoiding one temporary copy of the data.

TODO: try to optimize to allow completely streaming pass-through: currently will still read all data in memory buffers before outputting

Specified by:

getText in interface XMLStreamReader2

Parameters:

w - Writer to use for writing textual contents

preserveContents - If true, reader has to preserve contents so that further calls to getText will return proper conntets. If false, reader is allowed to skip creation of such copies: this can improve performance, but it also means that further calls to getText is not guaranteed to return meaningful data.

Returns:

Number of characters written to the reader

Throws:

java.io.IOException

javax.xml.stream.XMLStreamException

getDepth

public int getDepth()

Description copied from interface: XMLStreamReader2

Method that returns the number of open elements in the stack; 0 when the reader is in prolog/epilog, 1 inside root element (including when pointing at the root element itself) and so on. Depth is same for matching start/end elements, as well as for the all children of an element.

Specified by:

getDepth in interface XMLStreamReader2

Returns:

Number of open elements in the stack; 0 when parser is in prolog/epilog, 1 inside root element and so on.

isEmptyElement

public boolean isEmptyElement()
                       throws javax.xml.stream.XMLStreamException

Description copied from interface: XMLStreamReader2

Method that can be used to check whether current START_ELEMENT event was created for an empty element (xml short-hand notation where one tag implies start and end, ending with "/>"), or not.

Note: method may need to read more data to know if the element is an empty one, and as such may throw an i/o or parsing exception (as XMLStreamException); however, it won't throw exceptions for non-START_ELEMENT event types.

Specified by:

isEmptyElement in interface XMLStreamReader2

Returns:

True, if cursor points to a start or end element that is constructed from 'empty' element (ends with '/>'); false otherwise.

Throws:

javax.xml.stream.XMLStreamException

getNonTransientNamespaceContext

public javax.xml.namespace.NamespaceContext getNonTransientNamespaceContext()

Description copied from interface: XMLStreamReader2

This method returns a namespace context object that contains information identical to that returned by XMLStreamReader.getNamespaceContext(), but one that is not transient. That is, one that will remain valid and unchanged after its creation. This allows the namespace context to be used independent of its source documents life cycle. One possible use case is to use this namespace context for 'initializing' writers (especially ones that use repairing mode) with optimal/preferred name space bindings.

Specified by:

getNonTransientNamespaceContext in interface XMLStreamReader2

Returns:

Non-transient namespace context as explained above.

getPrefixedName

public java.lang.String getPrefixedName()

Description copied from interface: XMLStreamReader2

This method returns "prefix-qualified" name of the current element. In general, this means character-by-character exact name of the element in XML content, and may be useful in informational purposes, as well as when interacting with packages and APIs that use such names (such as what SAX may use as qnames).

Note: implementations are encouraged to provide an implementation that would be more efficient than calling getLocalName and getPrefix separately, but are not required to do so. Nonetheless it is usually at least as efficient (if not more) to call this method as to do it fully in calling code.

Specified by:

getPrefixedName in interface XMLStreamReader2

Returns:

Prefix-qualified name of the current element; essentially 'prefix:localName' if the element has a prefix, or 'localName' if it does not have one (belongs to the default namespace)

closeCompletely

public void closeCompletely()
                     throws javax.xml.stream.XMLStreamException

Description copied from interface: XMLStreamReader2

Method similar to XMLStreamReader.getNamespaceContext(), except that this method also does close the underlying input source if it has not yet been closed. It is generally preferable to call this method if the parsing ends in an exception; and for some input sources (when passing a File or URL for factory method) it has to be called as the application does not have access to the actually input source (InputStream opened from a URL and so on).

Specified by:

closeCompletely in interface XMLStreamReader2

Throws:

javax.xml.stream.XMLStreamException

getProcessedDTD

public java.lang.Object getProcessedDTD()

Specified by:

getProcessedDTD in interface DTDInfo

Returns:

If current event is DTD, DTD support is enabled, and reader supports DTD processing, returns an internal Object implementation uses for storing/processing DTD; otherwise returns null.

getDTDRootName

public java.lang.String getDTDRootName()

Specified by:

getDTDRootName in interface DTDInfo

Returns:

If current event is DTD, returns the full root name (including prefix, if any); otherwise returns null

getDTDPublicId

public java.lang.String getDTDPublicId()

Specified by:

getDTDPublicId in interface DTDInfo

Returns:

If current event is DTD, and has a public id, returns the public id; otherwise returns null.

getDTDSystemId

public java.lang.String getDTDSystemId()

Specified by:

getDTDSystemId in interface DTDInfo

Returns:

If current event is DTD, and has a system id, returns the system id; otherwise returns null.

getDTDInternalSubset

public java.lang.String getDTDInternalSubset()

Specified by:

getDTDInternalSubset in interface DTDInfo

Returns:

Internal subset portion of the DOCTYPE declaration, if any; empty String if none

getProcessedDTDSchema

public DTDValidationSchema getProcessedDTDSchema()

Description copied from interface: DTDInfo

Method similar to DTDInfo.getProcessedDTD(), but type-safe. Will return the DTD schema instance that was read, if we are in mode where it does get read (at least dtd-aware).

Specified by:

getProcessedDTDSchema in interface DTDInfo

getStartingByteOffset

public long getStartingByteOffset()

Description copied from interface: LocationInfo

Method that can be used to get exact byte offset (number of bytes read from the stream right before getting to this location) in the stream that is pointed to by this reader, right before the start of the current event.

Note: this value MAY be the same as the one returned by LocationInfo.getStartingCharOffset(), but usually only for single-byte character streams (Ascii, ISO-Latin).

Specified by:

getStartingByteOffset in interface LocationInfo

Returns:

Byte offset (== number of bytes reader so far) within the underlying stream, if the stream and stream reader are able to provide this (separate from the character offset, for variable-byte encodings); -1 if not.

getStartingCharOffset

public long getStartingCharOffset()

Description copied from interface: LocationInfo

Method that can be used to get exact character offset (number of chars read from the stream right before getting to this location) in the stream that is pointed to by this reader, right before the start of the current event.

Note: this value MAY be the same as the one returned by LocationInfo.getStartingByteOffset(); this is the case for single-byte character streams (Ascii, ISO-Latin), as well as for streams for which byte offset information is not available (Readers, Strings).

Specified by:

getStartingCharOffset in interface LocationInfo

Returns:

Character offset (== number of bytes reader so far) within the underlying stream, if the stream and stream reader are able to provide this (separate from byte offset, for variable-byte encodings); -1 if not.

getEndingByteOffset

public long getEndingByteOffset()
                         throws javax.xml.stream.XMLStreamException

Description copied from interface: LocationInfo

Method that can be used to get exact byte offset (number of bytes read from the stream right before getting to this location) in the stream that is pointed to by this reader, right after the end of the current event.

Note: this value MAY be the same as the one returned by LocationInfo.getEndingCharOffset(), but usually only for single-byte character streams (Ascii, ISO-Latin).

Note: for lazy-loading implementations, calling this method may require the underlying stream to be advanced and contents parsed; this is why it is possible that an exception be thrown.

Specified by:

getEndingByteOffset in interface LocationInfo

Returns:

Byte offset (== number of bytes reader so far) within the underlying stream, if the stream and stream reader are able to provide this (separate from the character offset, for variable-byte encodings); -1 if not.

Throws:

javax.xml.stream.XMLStreamException

getEndingCharOffset

public long getEndingCharOffset()
                         throws javax.xml.stream.XMLStreamException

Description copied from interface: LocationInfo

Method that can be used to get exact character offset (number of chars read from the stream right before getting to this location) in the stream that is pointed to by this reader, right after the end of the current event.

Note: this value MAY be the same as the one returned by LocationInfo.getEndingByteOffset(); this is the case for single-byte character streams (Ascii, ISO-Latin), as well as for streams for which byte offset information is not available (Readers, Strings).

Note: for lazy-loading implementations, calling this method may require the underlying stream to be advanced and contents parsed; this is why it is possible that an exception be thrown.

Specified by:

getEndingCharOffset in interface LocationInfo

Returns:

Character offset (== number of bytes reader so far) within the underlying stream, if the stream and stream reader are able to provide this (separate from byte offset, for variable-byte encodings); -1 if not.

Throws:

javax.xml.stream.XMLStreamException

getStartLocation

public XMLStreamLocation2 getStartLocation()

Description copied from interface: LocationInfo

An optional method that either returns the location object that points the starting position of the current event, or null if implementation does not keep track of it (some may return only end location; and some no location at all).

Note: since it is assumed that the start location must either have been collected by now, or is not accessible (i.e. implementation [always] returns null), no exception is allowed to be throws, as no parsing should ever need to be done (unlike with LocationInfo.getEndLocation()).

Specified by:

getStartLocation in interface LocationInfo

Returns:

Location of the first character of the current event in the input source (which will also be the starting location of the following event, if any, or EOF if not), or null (if implementation does not track locations).

getCurrentLocation

public XMLStreamLocation2 getCurrentLocation()

Description copied from interface: LocationInfo

A method that returns the current location of the stream reader at the input source. This is somewhere between the start and end locations (inclusive), depending on how parser does it parsing (for non-lazy implementations it's always the end location; for others something else).

Since this location information should always be accessible, no further parsing is to be done, and no exceptions can be thrown.

Specified by:

getCurrentLocation in interface LocationInfo

Returns:

Location of the next character reader will parse in the input source.

getEndLocation

public final XMLStreamLocation2 getEndLocation()
                                        throws javax.xml.stream.XMLStreamException

Description copied from interface: LocationInfo

An optional method that either returns the location object that points the ending position of the current event, or null if implementation does not keep track of it (some may return only start location; and some no location at all).

Note: since some implementations may not yet know the end location (esp. ones that do lazy loading), this call may require further parsing. As a result, this method may throw a parsing or I/O errors.

Specified by:

getEndLocation in interface LocationInfo

Returns:

Location right after the end of the current event (which will also be the start location of the next event, if any, or of EOF otherwise).

Throws:

javax.xml.stream.XMLStreamException - If the stream reader had to advance to the end of the event (to find the location), it may encounter a parsing (or I/O) error; if so, that gets thrown

validateAgainst

public XMLValidator validateAgainst(XMLValidationSchema schema)
                             throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that will construct a XMLValidator instance from the given schema (unless a validator for that schema has already been added), initialize it if necessary, and make validatable object (reader, writer) call appropriate validation methods from this point on until the end of the document (that is, it's not scoped with sub-trees), or until validator is removed by an explicit call to Validatable.stopValidatingAgainst(org.codehaus.stax2.validation.XMLValidationSchema).

Note that while this method can be called at any point in output processing, validator instances are not required to be able to handle addition at other points than right before outputting the root element.

Specified by:

validateAgainst in interface Validatable

Returns:

Validator instance constructed, if validator was added, or null if a validator for the schema has already been constructed.

Throws:

javax.xml.stream.XMLStreamException

stopValidatingAgainst

public XMLValidator stopValidatingAgainst(XMLValidationSchema schema)
                                   throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that can be called by application to stop validating output against a schema, for which Validatable.validateAgainst(org.codehaus.stax2.validation.XMLValidationSchema) was called earlier.

Specified by:

stopValidatingAgainst in interface Validatable

Returns:

Validator instance created from the schema that was removed, if one was in use; null if no such schema in use.

Throws:

javax.xml.stream.XMLStreamException

stopValidatingAgainst

public XMLValidator stopValidatingAgainst(XMLValidator validator)
                                   throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that can be called by application to stop validating output using specified validator. The validator passed should be an earlier return value for a call to Validatable.validateAgainst(org.codehaus.stax2.validation.XMLValidationSchema).

Note: the specified validator is compared for identity with validators in use, not for equality.

Specified by:

stopValidatingAgainst in interface Validatable

Returns:

Validator instance found (ie. argument validator) if it was being used for validating current document; null if not.

Throws:

javax.xml.stream.XMLStreamException

setValidationProblemHandler

public ValidationProblemHandler setValidationProblemHandler(ValidationProblemHandler h)

Description copied from interface: Validatable

Method that application can call to define a custom handler for validation problems encountered during validation process.

Specified by:

setValidationProblemHandler in interface Validatable

Parameters:

h - Handler to install, if non null; if null, indicates that the default (implementation-specific) handling should be used

Returns:

Previously set validation problem handler, if any; null if none was set
