Class GrammarImpl

java.lang.Object
  com.sun.xml.bind.GrammarImpl

All Implemented Interfaces:

com.sun.msv.grammar.Grammar, java.io.Serializable

public class GrammarImpl
extends java.lang.Object
implements com.sun.msv.grammar.Grammar, java.io.Serializable

Implementation of the Grammar interface with "plugs" that allows a grammar to be connected to other grammars when assembled through the context path.

These classes will be freeze-dried to "bgm.ser", so they must be serializable.

This class also implements a trick to allow a large grammar to be serialized without causing a stack overflow error. This is done by modifying the ElementExp.contentModel field to Expression.nullSet in the serialized form. The correct references will be restored after the grammar is deserialized.

Since:

1.0

createElement

public com.sun.msv.grammar.trex.ElementPattern createElement(com.sun.msv.grammar.NameClass nc,
                                                             com.sun.msv.grammar.Expression contentModel)

Creates a new ElementExp declaration inside this grammar.

While the other ordinary ElementExps can be also used, this ElementExp allows the grammar to be serialized without too much recursion.
