## org.apache.xerces.impl.xs
Class SchemaGrammar

    java.lang.Object
      |
      +--org.apache.xerces.impl.xs.SchemaGrammar

All Implemented Interfaces:
  org.apache.xerces.xni.grammars.Grammar, org.apache.xerces.xni.grammars.XSGrammar, org.apache.xerces.xs.XSNamespaceItem

Direct Known Subclasses:
  SchemaGrammar.BuiltinSchemaGrammar

public class SchemaGrammar
extends java.lang.Object
implements org.apache.xerces.xni.grammars.XSGrammar, org.apache.xerces.xs.XSNamespaceItem

This class is to hold all schema component declaration that are declared within one namespace. The Grammar class this class extends contains what little commonality there is between XML Schema and DTD grammars. It's useful to distinguish grammar objects from other kinds of object when they exist in pools or caches.
