Class ExpressionCloner

java.lang.Object

com.sun.msv.grammar.ExpressionCloner

All Implemented Interfaces:

ExpressionVisitorExpression

Direct Known Subclasses:

AttributePruner, AttributeRemover, ContentModelRefExpRemover.Remover, ExportedAttPoolGenerator, IslandSchemaImpl.Binder, NoneTypeRemover, RefExpRemover, SchemaLocationRemover

public abstract class ExpressionCloner
extends java.lang.Object
implements ExpressionVisitorExpression

clones an expression.

By visiting an expression, returns a cloned expression.

This class is useless by itself since expressions are shared and unified. It should be used as a base class for various AGM-related tasks to modify AGM.

Note that this class doesn't provide default implementations for onAttribute, onElement, and onRef methods. Typically, the derived class needs to do something to prevent infinite recursion.
