Method Detail

isAbsolutelyPositioned

public boolean isAbsolutelyPositioned()

Description copied from class: Area

Indicates whether this Area is positioned absolutely or relatively.

Specified by:

isAbsolutelyPositioned in class Area

Returns:

True iff this Area is absolutely positioned.

crOriginBPDOffset

public int crOriginBPDOffset()

Description copied from class: Area

The difference, in millipoints, between the page-viewport-area's before-edge and this Area's content-rectangle before-edge. This assumes for now that the BP Direction is the same for all areas.

Overrides:

crOriginBPDOffset in class AreaFlexible

Returns:

The BPD offset of the content rectangle.

getAreaName

public String getAreaName()

Specified by:

getAreaName in interface org.axsl.area.AreaNode

render

public void render(org.axsl.galley.RenderVisitor visitor)
            throws org.axsl.galley.GalleyVisitorException

Throws:

org.axsl.galley.GalleyVisitorException

getGraphic

public org.axsl.graphic.Graphic getGraphic()

Specified by:

getGraphic in interface org.axsl.galley.GraphicArea

crIpd

public int crIpd()

Specified by:

crIpd in interface org.axsl.area.Area

Specified by:

crIpd in class Area

crBpd

public int crBpd()

Specified by:

crBpd in interface org.axsl.area.Area

Specified by:

crBpd in class Area

contentStackingAxis

public org.axsl.common.value.RelativeAxis contentStackingAxis()

Description copied from class: Area

Returns the content stacking axis for this area.

Specified by:

contentStackingAxis in class Area

Returns:

Either RelativeAxis.BLOCK_PROGRESSION or RelativeAxis.INLINE_PROGRESSION, depending on whether the contents of this area stack in the block-progression-direction or the inline-progression-direction. The default value is that contents stack in the BPD. Classes that stack in the IPD should override this method.

getParent

public AreaNode getParent()

Specified by:

getParent in interface TreeNode

Specified by:

getParent in class AreaNode

setParent

public void setParent(AreaNode node)
               throws org.axsl.area.AreaTreeException

Description copied from class: AreaNode

Sets the parent node.

Specified by:

setParent in class AreaNode

Parameters:

node - The new parent node.

Throws:

org.axsl.area.AreaTreeException - If the parent node is not compatible with the implementations specification for a parent node.

getChildren

public List<AreaNode> getChildren()

Description copied from class: AbstractOrderedTreeNode

Return the List of this node's children.

Specified by:

getChildren in class AreaNode

Returns:

The List of this node's children.

getOverflowArea

public Area getOverflowArea(Area childRequesting)
                     throws org.axsl.area.AreaTreeException

Description copied from class: Area

This method is used by child Areas to ask the parent Area into which Area the child Area's overflow should be placed. Overflows start when a new LineArea cannot be create for the current BlockArea. General strategy for overflow is to recursively go up the tree until getting to any Area that knows how to solve the overflow. One general case is the page-reference-area, which should know how to create a new page.

Specified by:

getOverflowArea in class Area

Parameters:

childRequesting - Child Areas ask

Returns:

The younger sister Area that should be used to handle the overflow condition.

Throws:

org.axsl.area.AreaTreeException - If the Area is unable to find or create the overflow area.

setProgressionDimension

public void setProgressionDimension(int progressionDimension)

Description copied from class: Area

Sets the progression-dimension used by this Area.

Specified by:

setProgressionDimension in class Area

Parameters:

progressionDimension - The new progression-dimension value for this Area.

incrementProgressionDimension

public void incrementProgressionDimension(int incrementAmount)

Description copied from class: Area

Change the progression-dimension used by this Area.

Specified by:

incrementProgressionDimension in class Area

Parameters:

incrementAmount - The amount by which the progression-dimension should be changed for this area. Positive values increase the progression-dimension, negative values decrease it.

getProgressionDimension

public int getProgressionDimension()

Description copied from class: Area

Returns the actual total value, in millipoints, of the size of this area (not counting space-before, etc.) in its progression direction. This value does not include space-before, etc., but does include borders and padding. For block areas, the progression dimension is the block-progression-dimension. For inline areas, it is the inline-progression-dimension.

Specified by:

getProgressionDimension in class Area

Returns:

The progressionDimension.

optimize

protected boolean optimize()

Description copied from class: AreaNode

This method should be run after layout is complete, allowing cleanup and adjustments that do not affect the placement of the areas to be computed before the page is rendered. For example, empty areas should be removed. Also classes like LineArea can use this to adjust word-spacing and other variables. NOTE: This method is called recursively by each node. The process starts at PageRA.layoutComplete().

Specified by:

optimize in class AreaNode

Returns:

True iff the Area node thinks it should be removed.

Description copied from class: AreaNode

Returns the raw "generated by" instance.

getLinkage in class AreaNode

Returns:

The raw linkage item.
