addChildArea

public void addChildArea(Area childArea)

getChangedKnuthElements

public java.util.LinkedList getChangedKnuthElements(java.util.List oldList,
                                                    int alignment)

Description copied from interface: LayoutManager

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 possibile 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 InlineStackingLayoutManager

See Also:

LayoutManager.getChangedKnuthElements(List, int)

protected void addKnuthElementsForBorderPaddingEnd(java.util.List returnList)

Creates Knuth elements for end border padding and adds them to the return list.

Parameters:

returnList - return list to add the additional elements to

getAuxiliaryPosition

protected Position getAuxiliaryPosition()

Returns:

a cached auxiliary Position instance used for things like spaces.

addId

protected void addId()

Description copied from class: InlineStackingLayoutManager

This method is called by addAreas() so IDs can be added to a page for FOs that support the 'id' property.

Overrides:

LeafNodeLayoutManager.addId()
