Specified by:

Overrides:

getNextKnuthElements

public java.util.List getNextKnuthElements(LayoutContext context,
                                           int alignment,
                                           java.util.Stack lmStack,
                                           Position restartPosition,
                                           LayoutManager restartAtLM)
Returns an updated list of Knuth elements corresponding to this layout manager, after a change of IPD has been detected.

Specified by:
getNextKnuthElements in interface LayoutManager
Overrides:
getNextKnuthElements in class BlockStackingLayoutManager
Parameters:
context - the layout context
alignment - the alignment
lmStack - the stack of LMs that are active at the IPD change
restartPosition - the position corresponding to the element finishing the page before the IPD change
restartAtLM - if not null, the layout manager from which to restart. That is, the IPD change occurs between two block elements and not inside a paragraph
Returns:
an updated list of elements, taking the new IPD into account

addFirstVisibleMarks

protected void addFirstVisibleMarks(java.util.List<ListElement> elements,
                                    LayoutContext context,
                                    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 java.util.List getChangedKnuthElements(java.util.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

hasLineAreaDescendant

public boolean hasLineAreaDescendant()
Description copied from interface: LayoutManager
Whether the FO handled by this layout manager has a descendant (including itself) that will generate a line-area.

Specified by:
hasLineAreaDescendant in interface LayoutManager
Overrides:
hasLineAreaDescendant in class AbstractLayoutManager
Returns:
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:
