Enclosing class:
CachingParserPool
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.

    • retrieveInitialGrammarSet

      public org.apache.xerces.xni.grammars.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 org.apache.xerces.xni.grammars.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 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?
      Specified by:
      retrieveGrammar in interface org.apache.xerces.xni.grammars.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, org.apache.xerces.xni.grammars.Grammar[] grammars)
      Give the grammarPool the option of caching these grammars. This certainly must be synchronized.
      Specified by:
      cacheGrammars in interface org.apache.xerces.xni.grammars.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).

      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:
