pos
- the position referring to the needed word chars.- Returns:
- the word chars
-
hyphenate
public void hyphenate(Position pos, HyphContext hc)
Tell the LM to hyphenate a word- Specified by:
hyphenate
in interfaceInlineLevelLayoutManager

pos
- the Position referring to the wordhc
- the HyphContext storing hyphenation information
-
applyChanges
public boolean applyChanges(java.util.List oldList)
Tell the LM to apply the changes due to hyphenation- Specified by:
applyChanges
in 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
public boolean applyChanges(java.util.List oldList, int depth)
Tell the LM to apply the changes due to hyphenation- Specified by:
applyChanges
in interfaceInlineLevelLayoutManager

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:

-
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

oldList
