Class SAX2DTM

All Implemented Interfaces:
DTM, ContentHandler, DTDHandler, EntityResolver, ErrorHandler, DeclHandler, LexicalHandler
Direct Known Subclasses:

  • Method Details

    • setUseSourceLocation

      public void setUseSourceLocation(boolean useSourceLocation)
      Set whether information about document source location should be maintained or not.
    • clearCoRoutine

      public void clearCoRoutine()
      Ask the CoRoutine parser to doTerminate and clear the reference.
    • clearCoRoutine

      public void clearCoRoutine(boolean callDoTerminate)
      Ask the CoRoutine parser to doTerminate and clear the reference. If the CoRoutine parser has already been cleared, this will have no effect.
      Parameters:
      callDoTerminate - true of doTerminate should be called on the coRoutine parser.
    • setIncrementalSAXSource

      public void setIncrementalSAXSource(IncrementalSAXSource incrementalSAXSource)
      Bind a IncrementalSAXSource to this DTM. If we discover we need nodes that have not yet been built, we will ask this object to send us more events, and it will manage interactions with its data sources. Note that we do not actually build the IncrementalSAXSource, since we don't know what source it's reading from, what thread that source will run in, or when it will run.
      Parameters:
      incrementalSAXSource - The parser that we want to recieve events from on demand.
    • getContentHandler

      public String getNodeValue(int nodeHandle)
      Given a node handle, return its node value. This is mostly as defined by the DOM, but may ignore some conveniences.

      Specified by:
      getNodeValue in interface DTM
      Specified by:

    • getUnparsedEntityURI

      public String getUnparsedEntityURI(String name)
      The getUnparsedEntityURI function returns the URI of the unparsed entity with the specified name in the same document as the context node (see [3.3 Unparsed Entities]). It returns the empty string if there is no such entity.

      XML processors may choose to use the System Identifier (if one is provided) to resolve the entity, rather than the URI in the Public Identifier. The details are dependent on the processor, and we would have to support some form of plug-in resolver to handle this properly. Currently, we simply return the System Identifier if present, and hope that it a usable URI or that our caller can map it to one. TODO: Resolve Public Identifiers... or consider changing function name.

      If we find a relative URI reference, XML expects it to be resolved in terms of the base URI of the document. The DOM doesn't do that for us, and it isn't entirely clear whether that should be done here; currently that's pushed up to a higher level of our application. (Note that DOM Level 1 didn't store the document's base URI.) TODO: Consider resolving Relative URIs.

      (The DOM's statement that "An XML processor may choose to completely expand entities before the structure model is passed to the DOM" refers only to parsed entities, not unparsed, and hence doesn't affect this function.)

      Specified by:
      getUnparsedEntityURI in interface DTM
      Specified by:
      getUnparsedEntityURI in class DTMDefaultBase
      Parameters:
      name - A string containing the Entity Name of the unparsed entity.
      Returns:
      String containing the URI of the Unparsed Entity, or an empty string if no such entity exists.
    • getPrefix

      Specified by:
      getDocumentTypeDeclarationPublicIdentifier in class DTMDefaultBase
      Returns:

    • getElementById

      public int getElementById(String elementId)
      Returns the Element whose ID is given by elementId. If no such element exists, returns DTM.NULL. Behavior is not defined if more than one element has this ID. Attributes (including those with the name "ID") are not of type ID unless so defined by DTD/Schema information available to the DTM implementation. Implementations that do not know whether attributes are of type ID or not are expected to return DTM.NULL.

      %REVIEW% Presumably IDs are still scoped to a single document, and this operation searches only within a single document, right? Wouldn't want collisions between DTMs in the same process.

      Specified by:
      getElementById in interface DTM

    • warning

      public void warning(SAXParseException e) throws SAXException
      Receive notification of a parser warning.

      The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each warning, such as inserting the message in a log file or printing it to the console.

      Specified by:
      warning in interface ErrorHandler
      Parameters:
      e - The warning information encoded as an exception.
      Throws:
      SAXException - Any SAX exception, possibly wrapping another exception.

    • error

      public void error(SAXParseException e) throws SAXException
      Receive notification of a recoverable parser error.

      The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each error, such as inserting the message in a log file or printing it to the console.

      Specified by:
      error in interface ErrorHandler
      Parameters:
      e - The warning information encoded as an exception.

    • fatalError

      public void fatalError(SAXParseException e) throws SAXException
      Report a fatal XML parsing error.

      The default implementation throws a SAXParseException. Application writers may override this method in a subclass if they need to take specific actions for each fatal error (such as collecting all of the errors into a single report): in any case, the application must stop all regular processing when this method is invoked, since the document is no longer reliable, and the parser may no longer report parsing events.

      Specified by:
      fatalError in interface ErrorHandler
      Parameters:
      e - The error information encoded as an exception.
      Throws:
      SAXException - Any SAX exception, possibly wrapping another exception.

      Any declarations are assumed to be in the internal subset unless otherwise indicated by a startEntity event.

      Note that the start/endDTD events will appear within the start/endDocument events from ContentHandler and before the first startElement event.

      Specified by:
      startDTD in interface LexicalHandler
      Parameters:
      name - The document type name.

      value - an Object value
    • getSourceLocatorFor

      public SourceLocator getSourceLocatorFor(int node)
      Retrieve the SourceLocator associated with a specific node. This is only meaningful if the XalanProperties.SOURCE_LOCATION flag was set True using setProperty; if it was never set, or was set false, we will return null. (We _could_ return a locator with the document's base URI and bogus line/column information. Trying that; see the else clause.)
      Specified by:
      getSourceLocatorFor in interface DTM
      Parameters:
      node - an int value
      Returns:
      a SourceLocator value or null if no location is available
