public abstract class LeafNodeLayoutManager
extends AbstractLayoutManager
implements InlineLevelLayoutManager
Base LayoutManager for leaf-node FObj, ie: ones which have no children.
These are all inline objects. Most of them cannot be split (Text is
an exception to this rule.)
This class can be extended to handle the creation and adding of the
inline area.

childArea- the childArea to get the parent for- Returns:
- the parent area
-
setCommonBorderPaddingBackground
protected void setCommonBorderPaddingBackground(CommonBorderPaddingBackground commonBorderPaddingBackground) Set the border and padding properties of the inline area.- Parameters:
commonBorderPaddingBackground- the alignment adjust property
-
getAllocationIPD
Get the allocation ipd of the inline area. This method may be overridden to handle percentage values.- Parameters:
refIPD- the ipd of the parent reference area- Returns:
- the min/opt/max ipd of the inline area
-
addAreas
Add the area for this layout manager. This adds the single inline area to the parent.- Specified by:
addAreasin interfaceLayoutManager- Overrides:
addAreasin classAbstractLayoutManager- Parameters:
posIter- the position iteratorcontext- the layout context for adding the area
-
getEffectiveArea
- Returns:
- the effective area to be added to the area tree. Normally, this is simply "curArea" but in the case of page-number(-citation) curArea is cloned, updated and returned.
-
offsetArea
Offset this area. Offset the inline area in the bpd direction when adding the inline area. This is used for vertical alignment. Subclasses should override this if necessary.- Parameters:
area- the inline area to be updatedcontext- the layout context used for adding the area
-
makeAlignmentContext
Creates a new alignment context or returns the current alignment context. This is used for vertical alignment. Subclasses should override this if necessary.- Parameters:
context- the layout context used- Returns:
- the appropriate alignment context
-
widthAdjustArea
Adjust the width of the area when adding. This uses the min/opt/max values to adjust the with of the inline area by a percentage.- Parameters:
area- the inline area to be updatedcontext- the layout context for adding this area
-
getNextKnuthElements

addALetterSpaceToin interfaceInlineLevelLayoutManager- Parameters:
oldList- the elements which must be given one more letter space- Returns:
- the new elements replacing the old ones
-
addALetterSpaceTo

addALetterSpaceToin interfaceInlineLevelLayoutManager- Parameters:
oldList- the elements which must be given one more letter spacedepth- the depth at which the Positions for this LM in oldList are found- Returns:
- the new elements replacing the old ones
-
getWordChars
Get the word chars corresponding to the given position.- Specified by:
getWordCharsin interfaceInlineLevelLayoutManager- Parameters:
pos- the position referring to the needed word chars.- Returns:
- the word chars
-
hyphenate
Tell the LM to hyphenate a word- Specified by:
hyphenatein interfaceInlineLevelLayoutManager- Parameters:
pos- the Position referring to the wordhyphContext- the HyphContext storing hyphenation information
-
applyChanges
Tell the LM to apply the changes due to hyphenation- Specified by:
applyChangesin interfaceInlineLevelLayoutManager- Parameters:
oldList- the list of the old elements the changes refer to- Returns:
- true if the LM had to change its data, false otherwise
-
applyChanges
Tell the LM to apply the changes due to hyphenation Only TextLM has a meaningful implementation of this method- Specified by:
applyChangesin interfaceInlineLevelLayoutManager- Parameters:
oldList- the list of the old elements the changes refer todepth- the depth at which the Positions for this LM in oldList are found- Returns:
- true if the LM had to change its data, false otherwise
-
getChangedKnuthElements
public List<ListElement> getChangedKnuthElements(List<ListElement> oldList, int alignment, int depth) Get a sequence of KnuthElements representing the content of the node assigned to the LM, after changes have been applied No subclass has a meaningful implementation of this method- Specified by:
getChangedKnuthElementsin interfaceInlineLevelLayoutManager- Parameters:
oldList- the elements to replacealignment- the desired text alignmentdepth- the depth at which the Positions for this LM in oldList are found- Returns:
- the updated list of KnuthElements
-
getChangedKnuthElements
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:
getChangedKnuthElementsin interfaceLayoutManager- Overrides:
getChangedKnuthElementsin classAbstractLayoutManager- Parameters:
oldList- the elements to replacealignment- the desired text alignment- Returns:
- the updated list of KnuthElements
-

returnList- return list to add the additional elements to
-
addKnuthElementsForBorderPaddingEnd
