TextLayoutManager(FOText node)
Create a Text layout manager. |
Method Summary | |
---|---|
java.util.List |
addALetterSpaceTo(java.util.List oldList)
Tell the LM to modify its data, adding a letter space to the word fragment represented by the given elements, and returning the corrected elements |
void |
addAreas(PositionIterator posIter,
LayoutContext context)
Generate and add areas to parent area. |
boolean |
applyChanges(java.util.List oldList)
Tell the LM to apply the changes due to hyphenation |
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. |
java.util.List |
getNextKnuthElements(LayoutContext context,
int alignment)
Get a sequence of KnuthElements representing the content of the node assigned to the LM |
java.lang.String |
getWordChars(Position pos)
Get the word chars corresponding to the given position. |
void |
hyphenate(Position pos,
HyphContext hyphContext)
Tell the LM to hyphenate a word |
void |
initialize()
initialize the layout manager. |
void |
removeWordSpace(java.util.List oldList)
Removes the AreaInfo object represented by the given elements, so that it won't
generate any element when getChangedKnuthElements is called. |
