java.lang.Object org.apache.xerces.util.XMLGrammarPoolImpl
public class XMLGrammarPoolImpl
Stores grammars in a pool associated to a specific key. This grammar pool implementation stores two types of grammars: those keyed by the root element name, and those keyed by the grammar's target namespace. This is the default implementation of the GrammarPool interface. As we move forward, this will become more function-rich and robust.

public Grammar[] retrieveInitialGrammarSet(java.lang.String grammarType)
XMLGrammarPool
retrieve the initial known set of grammars. this method is called by a validator before the validation starts. the application can provide an initial set of grammars available to the current validation attempt.

- the type of the grammar, from the

interface.
public void cacheGrammars(java.lang.String grammarType, Grammar[] grammars)
XMLGrammarPool
return the final set of grammars that the validator ended up with. This method is called after the validation finishes. The application may then choose to cache some of the returned grammars.

XMLGrammarPool
This method requests that the application retrieve a grammar corresponding to the given GrammarIdentifier from its cache. If it cannot do so it must return null; the parser will then call the EntityResolver. An application must not call its EntityResolver itself from this method; this may result in infinite recursions.
