Constructor Detail

ListItemLayoutManager

public ListItemLayoutManager(ListItem node)

Create a new list item layout manager.

Parameters:

node - list-item to create the layout manager for

Method Detail

getListItemFO

protected ListItem getListItemFO()

Convenience method.

Returns:

the ListBlock node

setLabel

public void setLabel(ListItemLabel node)

Create a LM for the fo:list-item-label object

Parameters:

node - the fo:list-item-label FO

setBody

public void setBody(ListItemBody node)

Create a LM for the fo:list-item-body object

Parameters:

node - the fo:list-item-body FO

initialize

public void initialize()

initialize the layout manager. Allows each layout manager to calculate often used values.

Specified by:

initialize in interface LayoutManager

Overrides:

initialize in class AbstractLayoutManager

getNextKnuthElements

public java.util.List getNextKnuthElements(LayoutContext context,
                                  int alignment)

Get a sequence of KnuthElements representing the content of the node assigned to the LM.

Specified by:

getNextKnuthElements in interface LayoutManager

Overrides:

getNextKnuthElements in class BlockStackingLayoutManager

Parameters:

context - the LayoutContext used to store layout information

alignment - the desired text alignment

Returns:

the list of KnuthElements

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 class BlockStackingLayoutManager

Parameters:

elements - the element list

context - the layout context

alignment - 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 interface LayoutManager

Overrides:

getChangedKnuthElements in class BlockStackingLayoutManager

Parameters:

oldList - the elements to replace

alignment - the desired text alignment

Returns:

the updated list of KnuthElements

addAreas

public void addAreas(PositionIterator parentIter,
            LayoutContext layoutContext)

Add the areas for the break points.

Specified by:

addAreas in interface LayoutManager

Overrides:

addAreas in class AbstractLayoutManager

Parameters:

parentIter - the position iterator

layoutContext - 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 interface LayoutManager

Overrides:

getParentArea in class AbstractLayoutManager

Parameters:

childArea - the child area

Returns:

the parent are for the child

addChildArea

public void addChildArea(Area childArea)

Add the child. Rows return the areas returned by the child elements. This simply adds the area to the parent layout manager.

Specified by:

addChildArea in interface LayoutManager

Overrides:

addChildArea in class BlockStackingLayoutManager

Parameters:

childArea - the child area

getKeepTogetherProperty

public KeepProperty getKeepTogetherProperty()

Overrides:

getKeepTogetherProperty in class BlockStackingLayoutManager

Returns:

getKeepWithPreviousProperty in interface BlockLevelLayoutManager

Overrides:

getKeepWithPreviousProperty in class BlockStackingLayoutManager

Returns:

the keep-together property

getKeepWithNextProperty
