StandardParserConfiguration

public class StandardParserConfiguration extends DTDConfiguration
This is the "standard" parser configuration. It extends the DTD configuration with the standard set of parser components. The standard set of parser components include those needed to parse and validate with DTD's, and those needed for XML Schema.

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

  • Features
    • http://apache.org/xml/features/validation/schema
    • http://apache.org/xml/features/validation/schema-full-checking
    • http://apache.org/xml/features/validation/schema/normalized-value
    • http://apache.org/xml/features/validation/schema/element-default
  • Properties
    • http://apache.org/xml/properties/internal/error-reporter
    • http://apache.org/xml/properties/internal/entity-manager
    • http://apache.org/xml/properties/internal/document-scanner
    • http://apache.org/xml/properties/internal/dtd-scanner
    • http://apache.org/xml/properties/internal/grammar-pool
    • http://apache.org/xml/properties/internal/validator/dtd
    • http://apache.org/xml/properties/internal/datatype-validator-factory

Methods Summary
protected voidcheckFeature(java.lang.String featureId)
Check a feature. If feature is know and supported, this method simply returns. Otherwise, the appropriate exception is thrown.

param
featureId The unique identifier (URI) of the feature.
throws
XMLConfigurationException Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
