Class EncodingAlgorithmAttributesImpl

java.lang.Object

org.jvnet.fastinfoset.sax.helpers.EncodingAlgorithmAttributesImpl

All Implemented Interfaces:

EncodingAlgorithmAttributes, org.xml.sax.Attributes

public class EncodingAlgorithmAttributesImpl
extends java.lang.Object
implements EncodingAlgorithmAttributes

Default implementation of the EncodingAlgorithmAttributes interface.

This class provides a default implementation of the SAX2 EncodingAlgorithmAttributes interface, with the addition of manipulators so that the list can be modified or reused.

There are two typical uses of this class:

1. to take a persistent snapshot of an EncodingAlgorithmAttributes object in a startElement event; or
2. to construct or modify an EncodingAlgorithmAttributes object in a SAX2 driver or filter.
