Class AttributesImplSerializer

java.lang.Object
  org.xml.sax.helpers.AttributesImpl
      org.ajax4jsf.xml.serializer.AttributesImplSerializer

All Implemented Interfaces:

org.xml.sax.Attributes

public final class AttributesImplSerializer
extends org.xml.sax.helpers.AttributesImpl

This class extends org.xml.sax.helpers.AttributesImpl which implements org. xml.sax.Attributes. But for optimization this class adds a Hashtable for faster lookup of an index by qName, which is commonly done in the stream serializer.

Method Summary

void	addAttribute(java.lang.String uri, java.lang.String local, java.lang.String qname, java.lang.String type, java.lang.String val) This method adds the attribute, but also records its qName/index pair in the hashtable for fast lookup by getIndex(qName).
void	clear() This method clears the accumulated attributes.
int	getIndex(java.lang.String qname) This method gets the index of an attribute given its qName.
int	getIndex(java.lang.String uri, java.lang.String localName) This method gets the index of an attribute given its uri and locanName.
void	setAttributes(org.xml.sax.Attributes atts) This method sets the attributes, previous attributes are cleared, it also keeps the hashtable up to date for quick lookup via getIndex(qName).
