SAX2 extention handler to receive notification of encoding algorithm data.

This is an optional extension handler for SAX2. XML readers are not
required to recognize this handler, and it is not part of core-only
SAX2 distributions.


This interface may be used with with a Fast Infoset
SAX parser to receive notification of encoding algorithm data specified
in ITU-T Rec. X.891 | ISO/IEC 24824-1 (Fast Infoset) clause 10 and for
application defined encoding algorithms specified as part of the
initial vocabulary of a fast infoset document.


To set the EncodingAlgorithmContentHandler for an XML reader, use the setProperty method with the property name URI TO BE DEFINED and an object implementing this interface (or null) as the value. If the reader does not report primitive data types, it will throw a SAXNotRecognizedException


To set the EncodingAlgorithmContentHandler for an Fast Infoset reader, use 
 setEncodingAlgorithmContentHandler method.

public interface EncodingAlgorithmContentHandler {
    
Receive notification of encoding algorithm data as an array
of byte.

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


Such notifications will occur for a Fast Infoset SAX parser
when processing encoding algorithm data.


The Parser will call the method of this interface to report each
encoding algorithm data. Parsers MUST return all contiguous
characters in a single chunk


Parsers may return all contiguous bytes in a single chunk, or
they may split it into several chunks providing that the length of
each chunk is of the required length to successfully apply the
encoding algorithm to the chunk.


Params:
  • URI – the URI of the encoding algorithm
  • algorithm – the encoding algorithm index
  • b – the array of byte
  • start – the start position in the array
  • length – the number of byte to read from the array
Throws:
  • SAXException – any SAX exception, possibly
           wrapping another exception

Receive notification of encoding algorithm data as an object.

Such notifications will occur for a Fast Infoset SAX parser
when processing encoding algorithm data that is converted from an
array of byte to an object more suitable for processing.


Params:

  • algorithm – the encoding algorithm index
  • o – the encoding algorithm object
Throws:
  • SAXException – any SAX exception, possibly
