Method Detail

characters

public void characters(char[] ch,
                       int off,
                       int len)
                throws SAXException

Description copied from interface: ContentHandler

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.

Individual characters may consist of more than one Java char value. There are two important cases where this happens, because characters can't be represented in just sixteen bits. In one case, characters are represented in a Surrogate Pair, using two special Unicode values. Such characters are in the so-called "Astral Planes", with a code point above U+FFFF. A second case involves composite characters, such as a base character combining with one or more accent characters.

Your code should not assume that algorithms using char-at-a-time idioms will be working in character units; in some cases they will split characters. This is relevant wherever XML permits arbitrary characters, such as attribute values, processing instruction data, and comments as well as in data reported from this method. It's also generally relevant whenever Java code manipulates internationalized text; the issue isn't unique to XML.

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

getValue

public java.lang.String getValue()

characters

public void characters(java.lang.String characters)
                throws SAXException

Description copied from interface: ExtendedContentHandler

This method is used to notify of a character event, but passing the data as a character String rather than the standard character array.

Specified by:

characters in interface ExtendedContentHandler

Overrides:

characters in class EmptySerializer

Throws:

SAXException

See Also:

ExtendedContentHandler.characters(java.lang.String)

startElement

public void startElement(java.lang.String qname)
                  throws SAXException

Description copied from interface: ExtendedContentHandler

This method is used to notify of the start of an element

Specified by:

startElement in interface ExtendedContentHandler

Overrides:

startElement in class EmptySerializer

Throws:

SAXException

See Also:

ExtendedContentHandler.startElement(java.lang.String)

endElement

public void endElement(java.lang.String qname)
                throws SAXException

Description copied from interface: ExtendedContentHandler

This method is used to notify that an element has ended. Unlike the standard SAX method

 endElement(namespaceURI,localName,qName)
 

only the last parameter is passed. If needed the serializer can derive the localName from the qualified name and derive the namespaceURI from its implementation.

Specified by:

endElement in interface ExtendedContentHandler

Overrides:

endElement in class EmptySerializer

Throws:

SAXException

See Also:

ExtendedContentHandler.endElement(java.lang.String)

setEscaping

public boolean setEscaping(boolean bool)

Description copied from interface: SerializationHandler

Turns special character escaping on/off. Note that characters will never, even if this option is set to 'true', be escaped within CDATA sections in output XML documents.

Specified by:

setEscaping in interface SerializationHandler

Overrides:

setEscaping in class EmptySerializer

See Also:

SerializationHandler.setEscaping(boolean)

getValueOfPI

public java.lang.String getValueOfPI()

The value of a PI must not contain the substring "?>". Should that substring be present, replace it by "? >".
