public class InlineContainerLayoutManager extends AbstractLayoutManager implements InlineLevelLayoutManager
This creates a single inline container area after laying out the child block areas. All footnotes, floats and id areas are maintained for later retrieval.

      public List<KnuthSequence> getNextKnuthElements(LayoutContext context, int alignment)
      Description copied from class: AbstractLayoutManager
      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 AbstractLayoutManager
      Parameters:
      context - the LayoutContext used to store layout information

    • makeAlignmentContext

      protected AlignmentContext makeAlignmentContext(LayoutContext context)

    • addAreas

      public void addAreas(PositionIterator posIter, LayoutContext context)
      Description copied from class: AbstractLayoutManager
      Tell the layout manager to add all the child areas implied by Position objects which will be returned by the Iterator.
      Specified by:
      addAreas in interface LayoutManager
      Overrides:
      addAreas in class AbstractLayoutManager
      Parameters:
      posIter - the position iterator
      context - the context

    • getParentArea

      public Area getParentArea(Area childArea)
      Description copied from class: AbstractLayoutManager
      Return an Area which can contain the passed childArea. The childArea may not yet have any content, but it has essential traits set. In general, if the LayoutManager already has an Area it simply returns it. Otherwise, it makes a new Area of the appropriate class. It gets a parent area for its area by calling its parent LM. Finally, based on the dimensions of the parent area, it initializes its own area. This includes setting the content IPD and the maximum BPD.
      Specified by:
      getParentArea in interface LayoutManager
      Overrides:
      getParentArea in class AbstractLayoutManager
      Parameters:
      childArea - the child area for which the parent area is wanted
      Returns:
      the parent area for the given child

    • getContentAreaIPD

      public int getContentAreaIPD()
      Description copied from class: AbstractBaseLayoutManager
      Returns the IPD of the content area NOTE: Should be overridden by subclasses. Default implementation throws an UnsupportedOperationException.
      Specified by:
      getContentAreaIPD in interface LayoutManager
      Overrides:
      getContentAreaIPD in class AbstractBaseLayoutManager
      Returns:
      the IPD of the content area

    • getContentAreaBPD

      public int getContentAreaBPD()
      Description copied from class: AbstractBaseLayoutManager
      Returns the BPD of the content area NOTE: Should be overridden by subclasses. Default implementation throws an UnsupportedOperationException.
      Specified by:
      getContentAreaBPD in interface LayoutManager
      Overrides:
      getContentAreaBPD in class AbstractBaseLayoutManager
      Returns:
      the BPD of the content area

    • addChildArea

      public void addChildArea(Area childArea)
      Description copied from class: AbstractLayoutManager
      Add a child area to the current area. If this causes the maximum dimension of the current area to be exceeded, the parent LM is called to add it.
      Specified by:
      addChildArea in interface LayoutManager
      Overrides:
      addChildArea in class AbstractLayoutManager
      Parameters:
      childArea - the child area to be added
