Class GrammarImpl

java.lang.Object

com.sun.xml.bind.GrammarImpl

All Implemented Interfaces:

com.sun.msv.grammar.Grammar, Serializable

public class GrammarImpl
extends Object
implements com.sun.msv.grammar.Grammar, 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.

1.0

connect

public void connect(com.sun.msv.grammar.Grammar[] others)

Connect this grammar to other grammars.

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.
