ch - Character array.

i - position Where the surrogate was detected.

end - The end index of the significant characters.

Returns:

0 if the pair of characters was written out as-is, the unicode code point of the character represented by the surrogate pair if an entity reference with that value was written out.

                                 boolean escLF)
                          throws java.io.IOException

Parameters:

ch - character to be escaped.

i - index into character array.

chars - non-null reference to character array.

len - length of chars.

fromTextNode - true if the characters being processed are from a text node, false if they are from an attribute value

See Also:

startNonEscaping()

startNonEscaping

public void startNonEscaping()
                      throws org.xml.sax.SAXException

Starts an un-escaping section. All characters printed within an un- escaping section are printed as is, without escaping special characters into entity references. Only XML and HTML serializers need to support this method.

The contents of the un-escaping section will be delivered through the regular characters event.

Throws:

org.xml.sax.SAXException

cdata

protected void cdata(char[] ch,
                     int start,
                     int length)
              throws org.xml.sax.SAXException

Receive notification of cdata.

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).

Parameters:

ch - The characters from the XML document.

start - The start position in the array.

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

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

org.xml.sax.SAXException

characters

public void characters(char[] chars,
                       int start,
                       int length)
                throws org.xml.sax.SAXException

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).

Parameters:

chars - The characters from the XML document.

start - The start position in the array.

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

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
