All Implemented Interfaces:

JDOMFactory

public class SlimJDOMFactory
extends DefaultJDOMFactory

This JDOMFactory instance reduces the amount of memory used by JDOM content. It does this by reusing String instances instead of using new (but equals()) instances. It uses the StringBin class to provide a String cache.

Constructor Details

SlimJDOMFactory

public SlimJDOMFactory()

SlimJDOMFactory

public SlimJDOMFactory(boolean cachetext)

Construct a SlimJDOMFactory which will optionally cache Text/CDATA/Comment/Attribute values. Caching these values is recommended because often XML documents have many instances of the same Text values (especially whitespace sequences...)

Parameters:

cachetext - should be true if you want the content of CDATA, Text, Comment and Attribute values cached as well.
