  • Constructor Details

    • AbstractMetadataElement

      public AbstractMetadataElement(FONode parent)
      Main constructor.
      Parameters:
      parent - the parent formatting object

  • Method Details

    • getContentHandlerFactory

      public ContentHandlerFactory getContentHandlerFactory()
      This method is overridden by extension elements and allows the extension element to return a ContentHandlerFactory. This factory can create ContentHandler implementations that handle foreign XML content by either building up a specific DOM, a Java object or something else.
      Overrides:
      getContentHandlerFactory in class FONode
      Returns:
      the ContentHandlerFactory or null if not applicable

    • getExtensionAttachment

      public ExtensionAttachment getExtensionAttachment()
      This method is overridden by extension elements and allows the extension element to return a pass-through attachment which the parent formatting objects should simply carry with them but otherwise ignore. This mechanism is used to pass non-standard information from the FO tree through to the layout engine and the renderers.
      Overrides:
      getExtensionAttachment in class FONode
      Returns:
      the extension attachment if one is created by the extension element, null otherwise.

    • notifyObjectBuilt

      public void notifyObjectBuilt(Object obj)
      Notifies the listener when the object is fully built.
      Specified by:
      notifyObjectBuilt in interface ContentHandlerFactory.ObjectBuiltListener
      Parameters:
      obj - the newly built object
