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 interface: LayoutManager

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

Specified by:

initialize in interface LayoutManager

Overrides:

initialize in class AbstractLayoutManager

See Also:

LayoutManager.initialize()

getNextKnuthElements

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

Description copied from interface: LayoutManager

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

See Also:

BlockStackingLayoutManager

createNextChildLMs

public boolean createNextChildLMs(int pos)

Description copied from interface: LayoutManager

Create more child LMs of the parent, up to child LM index pos

Specified by:

createNextChildLMs in interface LayoutManager

Overrides:

createNextChildLMs in class AbstractLayoutManager

See Also:

LayoutManager.createNextChildLMs(int)

mustKeepTogether

public boolean mustKeepTogether()

Specified by:

mustKeepTogether in interface BlockLevelLayoutManager

Overrides:

mustKeepTogether in class BlockStackingLayoutManager

See Also:

BlockLevelLayoutManager.mustKeepTogether()

mustKeepWithPrevious

public boolean mustKeepWithPrevious()

Specified by:

mustKeepWithPrevious in interface BlockLevelLayoutManager

Overrides:

mustKeepWithPrevious in class BlockStackingLayoutManager

See Also:

BlockLevelLayoutManager.mustKeepWithPrevious()

mustKeepWithNext

public boolean mustKeepWithNext()

Specified by:

mustKeepWithNext in interface BlockLevelLayoutManager

Overrides:

mustKeepWithNext in class BlockStackingLayoutManager

See Also:

BlockLevelLayoutManager.mustKeepWithNext()

addAreas

public void addAreas(PositionIterator parentIter,
                     LayoutContext layoutContext)

Description copied from interface: LayoutManager

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

See Also:

LayoutManager.addAreas(org.apache.fop.layoutmgr.PositionIterator, org.apache.fop.layoutmgr.LayoutContext)

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)

Description copied from class: BlockStackingLayoutManager

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.

See Also:

LayoutManager.addChildArea(Area)

flush

protected void flush()

Force current area to be added to parent area.

Overrides:

flush in class BlockStackingLayoutManager

See Also:

BlockStackingLayoutManager.flush()

resetPosition

public void resetPosition(Position resetPos)

Description copied from interface: LayoutManager

Reset to the position.

Specified by:

resetPosition in interface LayoutManager

Overrides:

resetPosition in class AbstractLayoutManager

See Also:

LayoutManager.resetPosition(org.apache.fop.layoutmgr.Position)

getBlockFO

protected Block getBlockFO()

convenience method that returns the Block node

Returns:

the block node

getContentAreaIPD

public int getContentAreaIPD()

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
