public class XMLGrammarCachingConfiguration
extends XIncludeAwareParserConfiguration

This configuration provides a generic way of using Xerces's grammar caching facilities. It extends the XIncludeAwareParserConfiguration and thus may validate documents according to XML schemas or DTD's. It also allows the user to preparse a grammar, and to lock the grammar pool implementation such that no more grammars will be added.

Using the org.apache.xerces.xni.parser property, an application may instantiate a Xerces SAX or DOM parser with this configuration. When invoked in this manner, the default behaviour will be elicited; to use this configuration's specific facilities, the user will need to reference it directly.

In addition to the features and properties recognized by the base parser configuration, this class recognizes these additional features and properties:

is - The XMLInputSource containing this grammar's information If a URI is included in the systemId field, the parser will not expand this URI or make it available to the EntityResolver
Returns:
The newly created Grammar.
Throws:

Overrides:
checkFeature in class XML11Configuration
Parameters:
featureId - The unique identifier (URI) of the feature.
Throws:
org.apache.xerces.xni.parser.XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
