Class XMLNamespaceBinder

  • All Implemented Interfaces:
    XMLComponent, XMLDocumentFilter, XMLDocumentSource, XMLDocumentHandler
    Direct Known Subclasses:
    XML11NamespaceBinder

    public class XMLNamespaceBinder
    extends Object
    implements XMLComponent, XMLDocumentFilter
    This class performs namespace binding on the startElement and endElement method calls and passes all other methods through to the registered document handler. This class can be configured to only pass the start and end prefix mappings (start/endPrefixMapping).

    This component requires the following features and properties from the component manager that uses it:

    • http://xml.org/sax/features/namespaces
    • http://apache.org/xml/properties/internal/symbol-table
    • http://apache.org/xml/properties/internal/error-reporter

      • setOnlyPassPrefixMappingEvents

        public void setOnlyPassPrefixMappingEvents​(boolean onlyPassPrefixMappingEvents)
        Sets whether the namespace binder only passes the prefix mapping events to the registered document handler or passes all document events.
        Parameters:
        onlyPassPrefixMappingEvents - True to pass only the prefix mapping events; false to pass all events.
      • getOnlyPassPrefixMappingEvents

        public boolean getOnlyPassPrefixMappingEvents()
        Returns true if the namespace binder only passes the prefix mapping events to the registered document handler; false if the namespace binder passes all document events.
      • reset

        public void reset​(XMLComponentManager componentManager)
                   throws XNIException
        Resets the component. The component can query the component manager about any features and properties that affect the operation of the component.
        Specified by:
        reset in interface XMLComponent
        Parameters:
        componentManager - The component manager.
        Throws:
        SAXException - Thrown by component on initialization error. For example, if a feature or property is required for the operation of the component, the component manager may throw a SAXNotRecognizedException or a SAXNotSupportedException.
        XNIException - Thrown by component on initialization error.
      • getRecognizedFeatures

        public String[] getRecognizedFeatures()
        Returns a list of feature identifiers that are recognized by this component. This method may return null if no features are recognized by this component.
        Specified by:
        getRecognizedFeatures in interface XMLComponent
      • setFeature

        public void setFeature​(String featureId,
                               boolean state)
                        throws XMLConfigurationException
        Sets the state of a feature. This method is called by the component manager any time after reset when a feature changes state.

        Note: Components should silently ignore features that do not affect the operation of the component.

        Specified by:
        setFeature in interface XMLComponent
        Parameters:
        featureId - The feature identifier.
        state - The state of the feature.
        Throws:
        SAXNotRecognizedException - The component should not throw this exception.
        SAXNotSupportedException - The component should not throw this exception.
        XMLConfigurationException - Thrown for configuration error. In general, components should only throw this exception if it is really a critical error.
      • getRecognizedProperties

        public String[] getRecognizedProperties()
        Returns a list of property identifiers that are recognized by this component. This method may return null if no properties are recognized by this component.
        Specified by:
        getRecognizedProperties in interface XMLComponent
      • getFeatureDefault

        public Boolean getFeatureDefault​(String featureId)

        getFeatureDefault in interface XMLComponent
        Parameters:
        featureId - The feature identifier.

        name - The name of the general entity.
        identifier - The resource identifier.
        encoding - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal entities or a document entity that is parsed from a java.io.Reader).
        augs - Additional information that may include infoset augmentations
        Throws:
        XNIException - Thrown by handler to signal an error.

      • processingInstruction

                                   throws XNIException
        A processing instruction. Processing instructions consist of a target name and, optionally, text data. The data is only meaningful to the application.

        Typically, a processing instruction's data will contain a series of pseudo-attributes. These pseudo-attributes follow the form of element attributes but are not parsed or presented to the application as anything other than text. The application is responsible for parsing the data.

        Specified by:
        processingInstruction in interface XMLDocumentHandler
        Parameters:
        target - The target.
        data - The data or null if none specified.
        augs - Additional information that may include infoset augmentations
        Throws:
        XNIException - Thrown by handler to signal an error.

                          throws XNIException
        Binds the namespaces. This method will handle calling the document handler to start the prefix mappings.

        Specified by:
        startElement in interface XMLDocumentHandler
        Parameters:
        element - The name of the element.

        augs - Additional information that may include infoset augmentations
        Throws:
        XNIException - Thrown by handler to signal an error.

                                 throws XNIException
        Ignorable whitespace. For this method to be called, the document source must have some way of determining that the text containing only whitespace characters should be considered ignorable. For example, the validator can determine if a length of whitespace characters in the document are ignorable based on the element content model.

        The end of an element.
        Specified by:
        endElement in interface XMLDocumentHandler
        Parameters:
        element - The name of the element.

        This method notifies the end of a general entity.

        Note: This method is not called for entity references appearing as part of attribute values.

        Specified by:
        endGeneralEntity in interface XMLDocumentHandler
        Parameters:
        name - The name of the entity.
