Constructor and Description |
---|
AbstractLayoutManager()
Abstract layout manager.
|
AbstractLayoutManager(FObj fo)
Abstract layout manager.
|
Modifier and Type | Method and Description |
---|---|
void |
addAreas(PositionIterator posIter,
LayoutContext context)
Tell the layout manager to add all the child areas implied
by Position objects which will be returned by the
Iterator.
|
void |
addChildArea(Area childArea)
Add a child area to the current area.
|
void |
addChildLM(LayoutManager lm)
Add the LM in the argument to the list of child LMs;
set this LM as the parent;
initialize the LM.
|
void |
addChildLMs(java.util.List newLMs)
Add the LMs in the argument to the list of child LMs;
|
protected void |
addId()
Registers the FO's id on the current PageViewport
|
protected void |
addMarkersToPage(boolean isStarting,
boolean isFirst,
boolean isLast)
Registers the FO's markers on the current PageViewport
|
protected void |
checkEndOfLayout(Position pos)
Checks to see if the incoming
Position
is the last one for this LM, and if so, calls
notifyEndOfLayout() and cleans up. |
protected java.util.List<LayoutManager> |
createChildLMs(int size)
Create the LM instances for the children of the
formatting object being handled by this LM.
|
boolean |
createNextChildLMs(int pos)
Create more child LMs of the parent, up to child LM index pos
|
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.
|
protected LayoutManager |
getChildLM()
Return currently active child LayoutManager or null if
all children have finished layout.
|
java.util.List<LayoutManager> |
getChildLMs() |
Page |
getCurrentPage() |
PageViewport |
getCurrentPV() |
java.util.List |
getNextKnuthElements(LayoutContext context,
int alignment)
Get a sequence of KnuthElements representing the content
of the node assigned to the LM.
|
LayoutManager |
getParent()
Get the parent layout manager.
|
Area |
getParentArea(Area childArea)
Return an Area which can contain the passed childArea.
|
PageSequenceLayoutManager |
getPSLM()
Get the active PageSequenceLayoutManager instance for this
layout process.
|
protected boolean |
hasNextChildLM()
Return indication if getChildLM will return another LM.
|
void |
initialize()
initialize the layout manager.
|
boolean |
isFinished()
Tell whether this LayoutManager has handled all of its content.
|
boolean |
isFirst(Position pos)
Indicates whether the given Position is the first area-generating Position of this LM.
|
boolean |
isLast(Position pos)
Indicates whether the given Position is the last area-generating Position of this LM.
|
protected void |
notifyEndOfLayout()
Notifies the
PageSequenceLayoutManager that layout
for this LM has ended. |
Position |
notifyPos(Position pos)
Adds a Position to the Position participating in the first|last determination by assigning
it a unique position index.
|
void |
reset()
Re-initializes this layout manager in order to re-generate its Knuth
elements according to a new IPD value.
|
protected void |
setCurrentChildLM(LayoutManager childLM)
Set currently active child layout manager.
|
void |
setFinished(boolean fin)
Set the flag indicating the LayoutManager has handled all of its content.
|
void |
setParent(LayoutManager lm)
Set the parent layout manager.
|
java.lang.String |
toString() |
protected void |
transferExtensionAttachments(AreaTreeObject targetArea)
Transfers extension attachments from the formatting object to the area.
|
protected void |
transferExtensions(AreaTreeObject targetArea)
Transfers extensions (foreign attributes and extension attachments) from
the formatting object to the area.
|
protected void |
transferForeignAttributes(AreaTreeObject targetArea)
Transfers foreign attributes from the formatting object to the area.
