public class InstreamForeignObject extends AbstractGraphics
Class modelling the fo:instream-foreign-object object. This is an atomic inline object that contains XML data.

  • Field Details

    • intrinsicDimensions

      private Point2D intrinsicDimensions

    • instrisicSizeDetermined

      private boolean instrisicSizeDetermined

    • intrinsicAlignmentAdjust

      private Length intrinsicAlignmentAdjust

  • Constructor Details

    • InstreamForeignObject

      public InstreamForeignObject(FONode parent)
      Constructs an instream-foreign-object object (called by ElementMapping.Maker).
      Parameters:
      parent - the parent FONode

  • Method Details

    • startOfNode

      public void startOfNode() throws FOPException
      Description copied from class: FObj
      Called after processNode() is called. Subclasses can do additional processing.
      Overrides:
      startOfNode in class FObj
      Throws:
      FOPException - FOP Exception

    • endOfNode

      public void endOfNode() throws FOPException
      Make sure content model satisfied, if so then tell the FOEventHandler that we are at the end of the instream-foreign-object. Primarily used for making final content model validation checks and/or informing the FOEventHandler that the end of this FO has been reached. The default implementation simply calls FONode.finalizeNode(), without sending any event to the FOEventHandler.

      Note: the recommended way to override this method in subclasses is

      super.endOfNode(); // invoke finalizeNode()

      getFOEventHandler().endXXX(); // send endOfNode() notification

      Overrides:
      endOfNode in class FObj
      Throws:
      FOPException - FOP Exception

    • validateChildNode

      protected void validateChildNode(Locator loc, String nsURI, String localName) throws ValidationException
      Checks to make sure, during SAX processing of input document, that the incoming node is valid for this (parent) node (e.g., checking to see that fo:table is not an immediate child of fo:root) called from FOTreeBuilder.startElement(String, String, String, Attributes) before constructing the child FObj.
      XSL Content Model: one (1) non-XSL namespace child
      Overrides:
      validateChildNode in class FONode
      Parameters:
      loc - location in the FO source file
      nsURI - namespace of incoming node
      localName - name of the incoming node (without namespace prefix)
      Throws:
      ValidationException - if incoming node not valid for parent

    • getLocalName

      public String getLocalName()
      Returns the local name (i.e. without namespace prefix) of the node
      Specified by:
      getLocalName in class FONode
      Returns:
      the local name of this node

    • getNameId

      public int getNameId()
      Returns the Constants class integer value of this node
      Overrides:
      getNameId in class FONode
      Returns:
      Constants.FO_INSTREAM_FOREIGN_OBJECT

    • prepareIntrinsicSize

      private void prepareIntrinsicSize()
      Preloads the image so the intrinsic size is available.

    • getIntrinsicWidth

      public int getIntrinsicWidth()
      Specified by:
      getIntrinsicWidth in class AbstractGraphics
      Returns:
      the graphic's intrinsic width in millipoints

    • getIntrinsicHeight

      public int getIntrinsicHeight()
      Specified by:
      getIntrinsicHeight in class AbstractGraphics
      Returns:
      the graphic's intrinsic height in millipoints

    • getIntrinsicAlignmentAdjust

      public Length getIntrinsicAlignmentAdjust()
      Specified by:
      getIntrinsicAlignmentAdjust in class AbstractGraphics
      Returns:
      the graphic's intrinsic alignment-adjust

    • addChildNode

      protected void addChildNode(FONode child) throws FOPException
      Adds a node as a child of this node. The default implementation of this method just ignores any child node being added.
      Overrides:
      addChildNode in class FObj
      Parameters:
      child - child node to be added to the childNodes of this node
      Throws:
      FOPException - if there's a problem during processing

    • getChildXMLObj

      public XMLObj getChildXMLObj()
      Returns:
      the XMLObj child node of the instream-foreign-object.
