Class XMLAttributesImpl

java.lang.Object

org.htmlunit.cyberneko.xerces.util.XMLAttributesImpl

All Implemented Interfaces:

XMLAttributes

public class XMLAttributesImpl
extends Object
implements XMLAttributes

The XMLAttributesImpl class is an implementation of the XMLAttributes interface which defines a collection of attributes for an element. In the parser, the document source would scan the entire start element and collect the attributes. The attributes are communicated to the document handler in the startElement method.

The attributes are read-write so that subsequent stages in the document pipeline can modify the values or change the attributes that are propagated to the next stage.

Method Detail

addAttribute

public int addAttribute(QName name,
                        String type,
                        String value)

Adds an attribute. The attribute's non-normalized value of the attribute will have the same value as the attribute value. Also, the added attribute will be marked as specified in the XML instance document unless set otherwise using the setSpecified method.

Note: If an attribute of the same name already exists, the old values for the attribute are replaced by the new values.

Specified by:

addAttribute in interface XMLAttributes

Parameters:

name - The attribute name.

type - The attribute type. The type name is determined by the type specified for this attribute in the DTD. For example: "CDATA", "ID", "NMTOKEN", etc. However, attributes of type enumeration will have the type value specified as the pipe ('|') separated list of the enumeration values prefixed by an open parenthesis and suffixed by a close parenthesis. For example: "(true|false)".

value - The attribute value.

Returns:

Returns the attribute index.

See Also:

setSpecified(int, boolean)

addAttribute

public void addAttribute(QName name,
                         String type,
                         String value,
                         boolean specified)

Adds an attribute. The attribute's non-normalized value of the attribute will have the same value as the attribute value. Also, the added attribute will be marked as specified in the XML instance document unless set otherwise using the setSpecified method.

This method differs from addAttribute in that it does not check if an attribute of the same name already exists in the list before adding it. In order to improve performance of namespace processing, this method allows uniqueness checks to be deferred until all the namespace information is available after the entire attribute specification has been read.

Caution: If this method is called it should not be mixed with calls to addAttribute unless it has been determined that all the attribute names are unique.

Parameters:

name - the attribute name

type - the attribute type

value - the attribute value

specified - the specified attribute value

addAttribute

public void addAttribute(QName name,
                         String type,

                         String nonNormalizedValue,
                         boolean specified)

getType

public String getType(int index)

Look up an attribute's type by index.

The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).

If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommendation (clause 3.3.3, "Attribute-Value Normalization").

For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".

Specified by:

getType in interface XMLAttributes

Parameters:

index - The attribute index (zero-based).

Returns:

The attribute's type as a string, or null if the index is out of range.

See Also:

getLength()

getType

public String getType(String qname)

Look up an attribute's type by XML 1.0 qualified name.

See getType(int) for a description of the possible types.

Specified by:

getType in interface XMLAttributes

Parameters:

qname - The XML 1.0 qualified name.

Returns:

The attribute type as a string, or null if the attribute is not in the list or if qualified names are not available.

getValue

public String getValue(int index)

Look up an attribute's value by index.

If the attribute value is a list of tokens (IDREFS, ENTITIES, or NMTOKENS), the tokens will be concatenated into a single string with each token separated by a single space.

Specified by:

getValue in interface XMLAttributes

Parameters:

index - The attribute index (zero-based).

Returns:

The attribute's value as a string, or null if the index is out of range.

See Also:

See getValue(int) for a description of the possible values.

Specified by:

getValue in interface XMLAttributes

Parameters:

qname - The XML 1.0 qualified name.

Returns:

The attribute value as a string, or null if the attribute is not in the list or if qualified names are not available.

getNameRawName

public String getNameRawName(int index)

Return the name of an attribute in this list (by position).

The names must be unique: the SAX parser shall not include the same attribute twice. Attributes without values (those declared #IMPLIED without a value specified in the start tag) will be omitted from the list.

If the attribute name has a namespace prefix, the prefix will still be attached.

Parameters:

index - The index of the attribute in the list (starting at 0).

Returns:

The name of the indexed attribute, or null if the index is out of range.
