XMLGrammarCachingConfiguration (Xerces2 Implementation)

org.apache.xerces.parsers

## Class XMLGrammarCachingConfiguration

- java.lang.Object
- - org.apache.xerces.util.ParserConfigurationSettings
  - - org.apache.xerces.parsers.XML11Configuration
    - - org.apache.xerces.parsers.XIncludeAwareParserConfiguration
      - - org.apache.xerces.parsers.XMLGrammarCachingConfiguration

- All Implemented Interfaces:
    XML11Configurable, org.apache.xerces.xni.parser.XMLComponentManager, org.apache.xerces.xni.parser.XMLParserConfiguration, org.apache.xerces.xni.parser.XMLPullParserConfiguration

      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:

        `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.

    - #### checkProperty

          protected void checkProperty(java.lang.String propertyId)
                                throws org.apache.xerces.xni.parser.XMLConfigurationException

      Check a property. If the property is known and supported, this method simply returns. Otherwise, the appropriate exception is thrown.
      Overrides:
        `checkProperty` in class `XML11Configuration`

        `propertyId` - The unique identifier (URI) of the property being set.
      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.
