Class SAXOutputter


  • public class SAXOutputter
    extends Object
    Outputs a JDOM document as a stream of SAX2 events.

    Most ContentHandler callbacks are supported. BOTH ignorableWhitespace() and skippedEntity() have not been implemented. The JDOMLocator class returned by getLocator() exposes the current node being operated upon.

    At this time, it is not possible to access notations and unparsed entity references in a DTD from JDOM. Therefore, DTDHandler callbacks have not been implemented yet.

    The ErrorHandler callbacks have not been implemented, since these are supposed to be invoked when the document is parsed and at this point the document exists in memory and is known to have no errors.

        description: true indicates namespace URIs and unprefixed local names for element and attribute names will be available
        access: read/write, but always true!
        http://xml.org/sax/features/namespace-prefixes
        description: true indicates XML 1.0 names (with prefixes) and attributes (including xmlns* attributes) will be available
        access: read/write
        http://xml.org/sax/features/validation
        description: controls whether SAXOutputter is reporting DTD-related events; if true, the DocType internal subset will be parsed to fire DTD events
        access: read/write, defaults to true

        Parameters:
        name - String the feature name, which is a fully-qualified URI.
        value - boolean the requested state of the feature (true or false).
        Throws:
        SAXNotRecognizedException - when SAXOutputter does not recognize the feature name.
        SAXNotSupportedException - when SAXOutputter recognizes the feature name but cannot set the requested value.
      • setProperty

        public void setProperty​(String name,
                                Object value)

                                SAXNotSupportedException
        This will set the value of a SAX property. This method is also the standard mechanism for setting extended handlers.

        SAXOutputter currently supports the following SAX properties:

        http://xml.org/sax/properties/lexical-handler
        data type: org.xml.sax.ext.LexicalHandler
        description: An optional extension handler for lexical events like comments.
        access: read/write
        http://xml.org/sax/properties/declaration-handler
        data type: org.xml.sax.ext.DeclHandler
        description: An optional extension handler for DTD-related events other than notations and unparsed entities.
        access: read/write

        Parameters:
        name - String the property name, which is a fully-qualified URI.
        value - Object the requested value for the property.
        Throws:
        SAXNotRecognizedException - when SAXOutputter does not recognize the property name.
        SAXNotSupportedException - when SAXOutputter recognizes the property name but cannot set the requested value.

        Set the current SAXOutputProcessor to be used for output.
        Parameters:
        processor - the new SAXOutputProcessor
      • getFormat

        public Format getFormat()
        Get the current Format being used for output
        Returns:
        the current Format
      • setFormat

        public void setFormat​(Format format)
        Set the current Format to be used for output.
        Parameters:

      • output

        public void output​(Document document)
                    throws JDOMException
        This will output the JDOM Document, firing off the SAX events that have been registered.
        Parameters:
        document - JDOM Document to output.
        Throws:
        JDOMException - if any error occurred.
      • output

        public void output​(List<? extends Content> nodes)
                    throws JDOMException
        This will output a list of JDOM nodes as a document, firing off the SAX events that have been registered.

        Warning: This method may output ill-formed XML documents if the list contains top-level objects that are not legal at the document level (e.g. Text or CDATA nodes, multiple Element nodes, etc.). Thus, it should only be used to output document portions towards ContentHandlers capable of accepting such ill-formed documents (such as XSLT processors).

        Parameters:
        nodes - List of JDOM nodes to output.
        Throws:
        JDOMException - if any error occurred.

        output(org.jdom.Document)
      • output

        public void output​(Element node)
                    throws JDOMException
        This will output a single JDOM element as a document, firing off the SAX events that have been registered.
        Parameters:
        node - the Element node to output.
        Throws:
        JDOMException - if any error occurred.
      • getLocator

        @Deprecated
        public JDOMLocator getLocator()
        Deprecated.
        there is no way to get a meaningful document Locator outside of an active output process, and the contents of the locator are meaningless outside of an active output process anyway.
        Returns null.
        Returns:
        null
