      org.apache.xml.serializer.AttributesImplSerializer

All Implemented Interfaces:

Attributes

public final class AttributesImplSerializer

extends 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.

Usage:

**For internal use only**

Constructor Summary

AttributesImplSerializer()

Method Summary

void	addAttribute(String uri, String local, String qname, String type, 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(String qname) This method gets the index of an attribute given its qName.
int	getIndex(String uri, String localName) This method gets the index of an attribute given its uri and locanName.
void	setAttributes(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).

Parameters:

uri - the URI of the attribute

local - the local name of the attribute

qname - the qualified name of the attribute

type - the type of the attribute

val - the value of the attribute

clear

public final void clear()

This method clears the accumulated attributes.

setAttributes

public final void setAttributes(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).

Parameters:

atts - the attributes to copy into these attributes.

getIndex

public final int getIndex(String uri,
                          String localName)

This method gets the index of an attribute given its uri and locanName.

Parameters:

uri - the URI of the attribute name.

localName - the local namer (after the ':' ) of the attribute name.

Returns:

the integer index of the attribute.
