Enclosing class:

CachingParserPool

public static final class CachingParserPool.ShadowedGrammarPool

Method Detail

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"

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.

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).

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.

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.
