public static final class CachingParserPool.ShadowedGrammarPool
extends XMLGrammarPoolImpl

Shadowed grammar pool. This class is predicated on the existence of a concrete implementation; so using our own doesn't seem to bad an idea.

Constructor Detail

CachingParserPool.ShadowedGrammarPool

public CachingParserPool.ShadowedGrammarPool(org.apache.xerces.xni.grammars.XMLGrammarPool grammarPool)
Constructs a shadowed grammar pool.
Method Detail

retrieveInitialGrammarSet

public org.apache.xerces.xni.grammars.Grammar[] retrieveInitialGrammarSet(java.lang.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?
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 org.apache.xerces.xni.grammars.Grammar retrieveGrammar(org.apache.xerces.xni.grammars.XMLGrammarDescription gDesc)
Retrieve a particular grammar. REVISIT: does this need to be synchronized since it's just reading?
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(java.lang.String grammarType,
                          org.apache.xerces.xni.grammars.Grammar[] grammars)
Give the grammarPool the option of caching these grammars. This certainly must be synchronized.
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 org.apache.xerces.xni.grammars.Grammar getGrammar(org.apache.xerces.xni.grammars.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(org.apache.xerces.xni.grammars.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.
