Field Detail

proxyLMiter

protected java.util.ListIterator proxyLMiter
Iterator over the child layout managers.


childBreaks

protected java.util.List childBreaks
The list of child BreakPoss instances.

Constructor Detail

BlockLayoutManager

public BlockLayoutManager(Block inBlock)
Creates a new BlockLayoutManager.

Parameters:
inBlock - the block FO object to create the layout manager for.
Method Detail

initialize

public void initialize()
Description copied from class: AbstractLayoutManager
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.LinkedList 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 alignement
Returns:
the list of KnuthElements

createNextChildLMs

public boolean createNextChildLMs(int pos)
Create more child LMs of the parent, up to child LM index pos

Specified by:
createNextChildLMs in interface LayoutManager
Overrides:
createNextChildLMs in class AbstractLayoutManager
Parameters:
pos - index up to which child LMs are requested
Returns:
true if requested index does exist

mustKeepTogether

public boolean mustKeepTogether()

Specified by:
mustKeepTogether in interface BlockLevelLayoutManager
Overrides:
mustKeepTogether in class BlockStackingLayoutManager
Returns:
true if this element must be kept together

mustKeepWithPrevious

public boolean mustKeepWithPrevious()

Specified by:
mustKeepWithPrevious in interface BlockLevelLayoutManager
Overrides:
mustKeepWithPrevious in class BlockStackingLayoutManager
Returns:
true if this element must be kept with the previous element.

mustKeepWithNext

public boolean mustKeepWithNext()

Specified by:
mustKeepWithNext in interface BlockLevelLayoutManager
Overrides:
mustKeepWithNext in class BlockStackingLayoutManager
Returns:
true if this element must be kept with the next element.

addAreas

public void addAreas(PositionIterator parentIter,
                     LayoutContext layoutContext)
Tell the layout manager to add all the child areas implied by Position objects which will be returned by the Iterator.

Specified by:
addAreas in interface LayoutManager
Overrides:
addAreas in class AbstractLayoutManager
Parameters:
parentIter - the position iterator
layoutContext - the context

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 - area to get the parent area for
Returns:
the parent area

addChildArea

public void addChildArea(Area childArea)
Add the childArea to the current area. Called by child LayoutManager when it has filled one of its areas. The LM should already have an Area in which to put the child. See if the area will fit in the current area. If so, add it. Otherwise initiate breaking.

Specified by:
addChildArea in interface LayoutManager
Overrides:
addChildArea in class BlockStackingLayoutManager
Parameters:
childArea - the area to add: will be some block-stacked Area.

flush

protected void flush()
Force current area to be added to parent area. Force current area to be added to parent area.

Overrides:
flush in class BlockStackingLayoutManager

getBlockFO

protected Block getBlockFO()
convenience method that returns the Block node

Returns:
the block node

getContentAreaIPD

public int getContentAreaIPD()
Returns the IPD of the content area

Specified by:
getContentAreaIPD in interface LayoutManager
Overrides:
getContentAreaIPD in class BlockStackingLayoutManager
Returns:
the IPD of the content area

getContentAreaBPD

public int getContentAreaBPD()
Returns the BPD of the content area

Specified by:
getContentAreaBPD in interface LayoutManager
Overrides:
getContentAreaBPD in class BlockStackingLayoutManager
Returns:
the BPD of the content area

getGeneratesBlockArea

public boolean getGeneratesBlockArea()
Returns an indication if the layout manager generates a block area.

Specified by:
getGeneratesBlockArea in interface LayoutManager
Overrides:
getGeneratesBlockArea in class AbstractBaseLayoutManager
Returns:
True if the layout manager generates a block area

notifySpace

public void notifySpace(RelSide side,
                        MinOptMax effectiveLength)
Notifies the layout manager about the effective length of its space.

Specified by:
notifySpace in interface ConditionalElementListener
Parameters:
side - the side to which the space applies
effectiveLength - the effective length after space-resolution (null means zero length)

notifyBorder

public void notifyBorder(RelSide side,
                         MinOptMax effectiveLength)
Notifies the layout manager about the effective length/width of its border.

Specified by:
notifyBorder in interface ConditionalElementListener
Parameters:
side - the side to which the border applies
effectiveLength - the effective length in the current break situation (null means zero length)

notifyPadding

public void notifyPadding(RelSide side,
                          MinOptMax effectiveLength)
Notifies the layout manager about the effective length/width of its padding.

Specified by:
notifyPadding in interface ConditionalElementListener
Parameters:
side - the side to which the padding applies
effectiveLength - the effective length in the current break situation (null means zero length)
