                                              int alignment)

      Overridden to unconditionally add elements for space-before. Checks if this LM's first "visible marks" (= borders, padding, spaces) have already been processed, and if necessary, adds corresponding elements to the specified list, and updates the given layout context accordingly.
      Overrides:
        `addFirstVisibleMarks` in class `BlockStackingLayoutManager`
      Parameters:
        `elements` - the element list
        `context` - the layout context
        `alignment` - the vertical alignment

    - #### getChangedKnuthElements

          public List getChangedKnuthElements(List oldList,
                                              int alignment)

      Get a sequence of KnuthElements representing the content of the node assigned to the LM, after changes have been applied In the context of line breaking, this method is called after hyphenation has been performed, in order to receive the sequence of elements representing the text together with all possible hyphenation points. For example, if the text "representation" originates a single box element when getNextKnuthElements() is called, it will be now split in syllables (rep-re-sen-ta-tion) each one originating a box and divided by additional elements allowing a line break. In the context of page breaking, this method is called only if the pages need to be "vertically justified" modifying (also) the quantity of lines created by the paragraphs, and after a first page breaking has been performed. According to the result of the first page breaking, each paragraph now knows how many lines it must create (among the existing layout possibilities) and has to create a sequence of elements representing this layout; in particular, each box, representing a line, will contain a LineBreakPositions that will be used in the addAreas() phase. LMs having children look at the old list of elements in order to know which ones they must get the new elements from, as break conditions of preserved linefeeds can divide children into smaller groups (page sequences or paragraphs). LMs having no children can simply return the old elements if they have nothing to change. Inline LMs need to know the text alignment because it affects the elements representing feasible breaks between syllables.
      Specified by:
        `getChangedKnuthElements` in interface `LayoutManager`
      Overrides:
        `getChangedKnuthElements` in class `BlockStackingLayoutManager`
      Parameters:
        `oldList` - the elements to replace
        `alignment` - the desired text alignment
      Returns:
        the updated list of KnuthElements

        `true` if a descendant line-area will be generated, `false` otherwise

    - #### getBaselineOffset

          public int getBaselineOffset()

      Description copied from interface: `LayoutManager`
      Returns the position of the dominant-baseline of this FO's first descendant line-area.

      The behavior of this method is undefined if this FO has no descendant line-area, and an exception may be thrown. See `LayoutManager.hasLineAreaDescendant()`

      Specified by:
        `getBaselineOffset` in interface `LayoutManager`
      Overrides:
        `getBaselineOffset` in class `SpacedBorderedPaddedBlockLayoutManager`
      Returns:
        this FO's space-before plus the distance from the before-edge of its allocation-rectangle to the dominant-baseline of the first line-area descendant
      See Also:
        `LayoutManager.hasLineAreaDescendant()`

    - #### addAreas

          public void addAreas(PositionIterator parentIter,
                               LayoutContext layoutContext)

      Add the areas for the break points.
      Specified by:
        `addAreas` in interface `LayoutManager`
      Overrides:
        `addAreas` in class `AbstractLayoutManager`
      Parameters:
        `parentIter` - the position iterator
        `layoutContext` - the layout context for adding areas

    - #### getParentArea

          public Area getParentArea(Area childArea)

      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
      Returns:
        the parent are for the child

    - #### addChildArea

          public void addChildArea(Area childArea)

      Add the child. Rows return the areas returned by the child elements. This simply adds the area to the parent layout manager.
      Specified by:
        `addChildArea` in interface `LayoutManager`
      Overrides:
        `addChildArea` in class `BlockStackingLayoutManager`
      Parameters:
        `childArea` - the child area

    - #### getKeepTogetherProperty

          public KeepProperty getKeepTogetherProperty()

      Returns the keep-together property specified on the FObj. Default implementation throws a `IllegalStateException`. Must be implemented by the subclass, if applicable.
      Specified by:
        `getKeepTogetherProperty` in interface `BlockLevelLayoutManager`
      Overrides:
        `getKeepTogetherProperty` in class `BlockStackingLayoutManager`
      Returns:
        the keep-together property

    - #### getKeepWithPreviousProperty

          public KeepProperty getKeepWithPreviousProperty()

      Returns the keep-with-previous property specified on the FObj. Default implementation throws a `IllegalStateException`. Must be implemented by the subclass, if applicable.
      Specified by:
        `getKeepWithPreviousProperty` in interface `BlockLevelLayoutManager`
      Overrides:
        `getKeepWithPreviousProperty` in class `BlockStackingLayoutManager`
      Returns:
        the keep-together property

    - #### getKeepWithNextProperty

          public KeepProperty getKeepWithNextProperty()

      Returns the keep-with-next property specified on the FObj. Default implementation throws a `IllegalStateException`. Must be implemented by the subclass, if applicable.
      Specified by:
        `getKeepWithNextProperty` in interface `BlockLevelLayoutManager`
      Overrides:
        `getKeepWithNextProperty` in class `BlockStackingLayoutManager`
      Returns:
        the keep-together property

    - #### reset

          public void reset()

      Re-initializes this layout manager in order to re-generate its Knuth elements according to a new IPD value.
      Specified by:
        `reset` in interface `LayoutManager`
      Overrides:
        `reset` in class `BlockStackingLayoutManager`

    - #### getBreakBefore

          public int getBreakBefore()

      Description copied from class: `BlockStackingLayoutManager`
      Returns the highest priority break-before value on this layout manager or its relevant descendants.

    - #### isRestartable

          public boolean isRestartable()

      Returns `true` if this layout manager is able to re-generate its Knuth elements after an IPD change.
      Specified by:
        `isRestartable` in interface `LayoutManager`
      Overrides:
        `isRestartable` in class `AbstractBaseLayoutManager`
