      ipd - the inline progression to increase by
    • setBlockProgressionOffset

      public void setBlockProgressionOffset(int blockProgressionOffset)
      Set the block progression offset of this inline area. This is used to set the offset of the inline area which is relative to the before edge of the parent area.
      Parameters:
      blockProgressionOffset - the offset
    • getBlockProgressionOffset

      public int getBlockProgressionOffset()
      Get the block progression offset of this inline area. This returns the offset of the inline area relative to the before edge of the parent area.

      public void setParentArea(Area parentArea)
      Parameters:
      parentArea - The parentArea to set.

      Returns:
      Returns the parentArea.
    • addChildArea

      public void addChildArea(Area childArea)
      Set the parent for the child area. Add a child to this area. The default is to do nothing. Subclasses must override to do something if they can have child areas.
      Overrides:
      addChildArea in class Area
      Parameters:
      childArea - the child area to add
    • hasUnderline

    • getVirtualOffset

      int getVirtualOffset()
      Returns the offset that this area would have if its offset and size were taking children areas into account. The bpd of an inline area is taken from its nominal font and doesn't depend on the bpds of its children elements. However, in the case of a basic-link element we want the active area to cover all of the children elements.
      Returns:
      the offset that this area would have if the before-edge of its content-rectangle were coinciding with the beforest before-edge of its children allocation-rectangles.
      See Also:
    • getVirtualBPD

      int getVirtualBPD()
      Returns the block-progression-dimension that this area would have if it were taking its children elements into account. See getVirtualOffset().
      Returns:
      the bpd
