Constructor Detail

CachingParserPool.ShadowedGrammarPool

public CachingParserPool.ShadowedGrammarPool(XMLGrammarPool grammarPool)
Constructs a shadowed grammar pool.

Method Detail

cacheGrammars

public void cacheGrammars(String grammarType,
                          Grammar[] grammars)
Give the grammarPool the option of caching these grammars. This certainly must be synchronized.

Specified by:
cacheGrammars in interface XMLGrammarPool
Overrides:
cacheGrammars in class XMLGrammarPoolImpl
Parameters:
grammarType - The type of the grammars to be cached.
grammars - The Grammars that may be cached (unordered, Grammars previously given to the validator may be included).

containsGrammar

public boolean containsGrammar(XMLGrammarDescription desc)
Returns true if the grammar pool contains a grammar associated to the specified description.

Overrides:
containsGrammar in class XMLGrammarPoolImpl
Parameters:
desc - The description of the grammar.

getGrammar

public Grammar getGrammar(XMLGrammarDescription desc)
Returns the grammar associated to the specified description.

Overrides:
getGrammar in class XMLGrammarPoolImpl
Parameters:
desc - The description of the grammar.

retrieveGrammar

public Grammar retrieveGrammar(XMLGrammarDescription gDesc)
Retrieve a particular grammar. REVISIT: does this need to be synchronized since it's just reading?

Specified by:
retrieveGrammar in interface XMLGrammarPool
Overrides:
retrieveGrammar in class XMLGrammarPoolImpl
Parameters:
gDesc - Description of the grammar to be retrieved
Returns:
Grammar corresponding to gDesc, or null if none exists.

retrieveInitialGrammarSet

public Grammar[] retrieveInitialGrammarSet(String grammarType)
Retrieve the initial set of grammars for the validator to work with. REVISIT: does this need to be synchronized since it's just reading?

Specified by:
retrieveInitialGrammarSet in interface XMLGrammarPool
Overrides:
retrieveInitialGrammarSet in class XMLGrammarPoolImpl
Parameters:
grammarType - Type of the grammars to be retrieved.
Returns:
The initial grammar set the validator may place in its "bucket"
