Class CharacterSetFactory

java.lang.Object
  extended by net.sf.saxon.serialize.charcode.CharacterSetFactory

public class CharacterSetFactory
extends Object

This class delivers a CharacterSet object for a given named encoding. It maintains a mapping from character set names to class names, and a separate mapping from character set names to instances of those classes. This means that a class is not actually instantiated until the encoding is used, but once instantiated, the same instance is used whenever that encoding is used again in the same Configuration. Note that the purpose of the CharacterSet object is only to record which Unicode characters are represented in the encoding, so that non-encodable characters can be represented as XML or HTML character references. The actual translation from Unicode codepoints to bytes in the chosen encoding is left to the Java IO library.
