    • Method Detail

      • getInlineArea

        private InlineViewport getInlineArea()
        Get the inline area created by this element.
        Returns:

      • getNextKnuthElements

        public java.util.List getNextKnuthElements​(LayoutContext context,
                                                   int alignment)
        Get a sequence of KnuthElements representing the content of the node assigned to the LM.
        Specified by:
        getNextKnuthElements in interface LayoutManager
        Overrides:
        getNextKnuthElements in class LeafNodeLayoutManager
        Parameters:
        context - the LayoutContext used to store layout information
        alignment - the desired text alignment
        Returns:
        the list of KnuthElements
      • getEffectiveArea

        protected InlineArea getEffectiveArea​(LayoutContext layoutContext)
        Overrides:
        getEffectiveArea in class LeafNodeLayoutManager
        Returns:
        the effective area to be added to the area tree. Normally, this is simply "curArea" but in the case of page-number(-citation) curArea is cloned, updated and returned.
      • makeAlignmentContext

        protected AlignmentContext makeAlignmentContext​(LayoutContext context)
        Creates a new alignment context or returns the current alignment context. This is used for vertical alignment. Subclasses should override this if necessary.
        Overrides:
        makeAlignmentContext in class LeafNodeLayoutManager
        Parameters:
        context - the layout context used
        Returns:
        the appropriate alignment context
      • getChildArea

        protected abstract Area getChildArea()
        Returns the image of foreign object area to be put into the viewport.
        Returns:
        the appropriate area
      • getBaseLength

        public int getBaseLength​(int lengthBase,
                                 FObj fobj)
        Returns the base length for the given length base. Length base should be one of the constants defined in LengthBase.
        Specified by:
        getBaseLength in interface PercentBaseContext
        Overrides:
        getBaseLength in class AbstractBaseLayoutManager
        Parameters:
        lengthBase - Indicates which type of the base length value is to be returned
        fobj - The FO object against which the percentage should be evaluated
        Returns:
        The base length value of the given kind
