retrieveInitialGrammarSet

public Grammar[] retrieveInitialGrammarSet(java.lang.String grammarType)

Description copied from interface: 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.

Parameters:

grammarType - the type of the grammar, from the org.apache.xerces.xni.grammars.Grammar interface.

Returns:

the set of grammars the validator may put in its "bucket"

retrieveGrammar

public Grammar retrieveGrammar(XMLGrammarDescription gDesc)

Description copied from interface: 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.

retrieveGrammar in interface XMLGrammarPool

Parameters:

gDesc - The description of the Grammar being requested.

Returns:

the Grammar corresponding to this description or null if no such Grammar is known.

cacheGrammars
