private void resetSpaces()
-
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 interfaceLayoutManager
- Overrides:
getNextKnuthElements
in classBlockStackingLayoutManager
- Parameters:
context
- the layout contextalignment
- the alignmentlmStack
- the stack of LMs that are active at the IPD changerestartPosition
- the position corresponding to the element finishing the page before the IPD changerestartAtLM
- 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 classBlockStackingLayoutManager
- Parameters:
elements
- the element listcontext
- the layout contextalignment
- 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 interfaceLayoutManager
- Overrides:
getChangedKnuthElements
in classBlockStackingLayoutManager
- Parameters:
oldList
- the elements to replacealignment
- 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 interfaceLayoutManager
- Overrides:
hasLineAreaDescendant
in classAbstractLayoutManager
- 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 interfaceLayoutManager
- Overrides:
getBaselineOffset
in classSpacedBorderedPaddedBlockLayoutManager
- 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 interfaceLayoutManager
- Overrides:
addAreas
in classAbstractLayoutManager
- Parameters:
parentIter
- the position iteratorlayoutContext
- 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 interfaceLayoutManager
- Overrides:
getParentArea
in classAbstractLayoutManager
- Parameters:
childArea
- the child area- Returns:
- the parent are for the child
