Class DOMForest

  • public final class DOMForest
extends Object
    Builds a DOM forest and maintains association from system IDs to DOM trees.

    A forest is a transitive reflexive closure of referenced documents. IOW, if a document is in a forest, all the documents referenced from it is in a forest, too. To support this semantics, DOMForest uses InternalizationLogic to find referenced documents.

    Some documents are marked as "root"s, meaning those documents were put into a forest explicitly, not because it is referenced from another document. (However, a root document can be referenced from other documents, too.)

    • Field Detail

      • locatorTable

        public final LocatorTable locatorTable
        Stores location information for all the trees in this forest.

      • outerMostBindings

        public final Set<Element> outerMostBindings
        Stores all the outer-most <jaxb:bindings> customizations.

      • logic

        protected final InternalizationLogic logic
        Schema language dependent part of the processing.

    • Method Detail

      • get

        public Document get​(String systemId)
        Gets the DOM tree associated with the specified system ID, or null if none is found.

      • getRootDocuments

        public Set<String> getRootDocuments()
        Returns a read-only set of root document system IDs.

      • getOneDocument

        public Document getOneDocument()
        Picks one document at random and returns it.

      • checkSchemaCorrectness

        public boolean checkSchemaCorrectness​(ErrorReceiver errorHandler)
        Checks the correctness of the XML Schema documents and return true if it's OK.

        This method performs a weaker version of the tests where error messages are provided without line number information. So whenever possible use SchemaConstraintChecker.

      • getSystemId

        public String getSystemId​(Document dom)
        Gets the system ID from which the given DOM is parsed.

        Poor-man's base URI.

      • getParserHandler

        public DOMForest.Handler getParserHandler​(String systemId,
                                          boolean root)
        Returns a ContentHandler to feed SAX events into.

        The client of this class can feed SAX events into the handler to parse a document into this DOM forest.

      • parse

        public Document parse​(String systemId,
                      InputSource inputSource,
                      boolean root)
               throws SAXException
        Parses the given document and add it to the DOM forest.
        Returns:
        null if there was a parse error. otherwise non-null.
        Throws:
        SAXException

      • transform

        public SCDBasedBindingSet transform​(boolean enableSCD)
        Performs internalization. This method should be called only once, only after all the schemas are parsed.
        Returns:
        the returned bindings need to be applied after schema components are built.

      • weakSchemaCorrectnessCheck

        public void weakSchemaCorrectnessCheck​(SchemaFactory sf)
        Performs the schema correctness check by using JAXP 1.3.

        This is "weak", because SchemaFactory.newSchema(Source[]) doesn't handle inclusions very correctly (it ends up parsing it from its original source, not in this tree), and because it doesn't handle two documents for the same namespace very well.

        We should eventually fix JAXP (and Xerces), but meanwhile this weaker and potentially wrong correctness check is still better than nothing when used inside JAX-WS (JAXB CLI and Ant does a better job of checking this.)

        To receive errors, use SchemaFactory.setErrorHandler(ErrorHandler).

      • createSAXSource

        @NotNull
public SAXSource createSAXSource​(String systemId)
        Creates a SAXSource that, when parsed, reads from this DOMForest (instead of parsing the original source identified by the system ID.)

      • createParser

        public XMLParser createParser()
        Creates XMLParser for XSOM which reads documents from this DOMForest rather than doing a fresh parse. The net effect is that XSOM will read transformed XML Schemas instead of the original documents.

      • setEntityResolver

        public void setEntityResolver​(EntityResolver entityResolver)

      • setErrorHandler

        public void setErrorHandler​(ErrorReceiver errorHandler)

      • listDocuments

        public Document[] listDocuments()
        Gets all the parsed documents.

      • listSystemIDs

        public String[] listSystemIDs()
        Gets all the system IDs of the documents.

      • dump

        public void dump​(OutputStream out)
          throws IOException
        Dumps the contents of the forest to the specified stream. This is a debug method. As such, error handling is sloppy.
        Throws:
        IOException
