Class PageSequence

    • Constructor Detail

      • PageSequence

        public PageSequence​(FONode parent)

    • Method Detail

      • bind

        public void bind​(PropertyList pList)
          throws FOPException
        Bind property values from the property list to the FO node. Must be overridden in all FObj subclasses that have properties applying to it.
        Overrides:
        bind in class AbstractPageSequence
        Parameters:
        pList - the PropertyList where the properties can be found.
        Throws:
        FOPException - if there is a problem binding the values

      • endOfNode

        public void endOfNode()
               throws FOPException
        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 FONode
        Throws:
        FOPException - if there's a problem during processing

      • validateChildNode

        protected void validateChildNode​(org.xml.sax.Locator loc,
                                 java.lang.String nsURI,
                                 java.lang.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: (title?,static-content*,flow)
        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

      • addChildNode

        public 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. TODO see if addChildNode() should also be called for fo's other than fo:flow.
        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
