DTDEventListener.endDTD()

comment

public void comment(String n)
             throws SAXException

Description copied from interface: DTDEventListener

Receive notification that a comment has been read.

Note that processing instructions are the mechanism designed to hold information for consumption by applications, not comments. XML systems may rely on applications being able to access information found in processing instructions; this is not true of comments, which are typically discarded.

Specified by:

comment in interface DTDEventListener

Parameters:

n - the text within the comment delimiters.

Throws:

SAXException

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws SAXException

Description copied from interface: DTDEventListener

Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

Specified by:

characters in interface DTDEventListener

Parameters:

ch - The characters from the DTD.

start - The start position in the array.

length - The number of characters to read from the array.

Throws:

SAXException

See Also:

DTDEventListener.ignorableWhitespace(char[], int, int)

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,
                                int length)
                         throws SAXException

Description copied from interface: DTDEventListener

Receive notification of ignorable whitespace in element content.

Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Specified by:

ignorableWhitespace in interface DTDEventListener

Parameters:

ch - The characters from the DTD.

start - The start position in the array.

length - The number of characters to read from the array.

Throws:

SAXException

public void startContentModel(String elementName,
                              short contentModelType)
                       throws SAXException

Description copied from interface: DTDEventListener

receives notification that parsing of content model is beginning.

Specified by:

startContentModel in interface DTDEventListener

Parameters:

elementName - name of the element whose content model is going to be defined.

contentModelType - DTDEventListener.CONTENT_MODEL_EMPTY this element has EMPTY content model. This notification will be immediately followed by the corresponding endContentModel. DTDEventListener.CONTENT_MODEL_ANY this element has ANY content model. This notification will be immediately followed by the corresponding endContentModel. DTDEventListener.CONTENT_MODEL_MIXED this element has mixed content model. #PCDATA will not be reported. each child element will be reported by mixedElement method. DTDEventListener.CONTENT_MODEL_CHILDREN this elemen has child content model. The actual content model will be reported by childElement, startModelGroup, endModelGroup, and connector methods. Possible call sequences are:

START := MODEL_GROUP MODEL_GROUP := startModelGroup TOKEN (connector TOKEN)* endModelGroup TOKEN := childElement | MODEL_GROUP

Description copied from interface: DTDEventListener
