DEFAULT_SPACE_WIDTH
this constant is used to create elements when text-align is center:
every TextLM descendant of LineLM must use the same value,
otherwise the line breaking algorithm does not find the right
break point

Constructor and Description |
---|
LineLayoutManager(Block block,
Length lh,
int l,
int f)
Create a new Line Layout Manager.
|
Modifier and Type | Method and Description |
---|---|
void |
addAreas(PositionIterator parentIter,
LayoutContext context)
Add the areas with the break points.
|
void |
addChildArea(Area childArea)
Add a child area to the current area.
|
void |
discardSpace(KnuthGlue spaceGlue)
Discard space.
|
int |
getBaselineOffset()
Returns the position of the dominant-baseline of this FO's first descendant
line-area.
|
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.
|
java.util.List |
getChangedKnuthElements(java.util.List oldList,
int alignment,
int depth)
Get a sequence of KnuthElements representing the content
of the node assigned to the LM, after changes have been applied
|
boolean |
getGeneratesBlockArea()
Returns an indication if the layout manager generates a block area.
|
boolean |
getGeneratesLineArea()
Returns an indication if the layout manager generates a line area.
|
Keep |
getKeepTogether()
Returns the keep-together strength for this element.
|
KeepProperty |
getKeepTogetherProperty()
Returns the keep-together property specified on the FObj.
|
Keep |
getKeepWithNext()
Returns the keep-with-next strength for this element.
|
KeepProperty |
getKeepWithNextProperty()
Returns the keep-with-next property specified on the FObj.
|
Keep |
getKeepWithPrevious()
Returns the keep-with-previous strength for this element.
|
KeepProperty |
getKeepWithPreviousProperty()
Returns the keep-with-previous property specified on the FObj.
|
java.util.List |
getNextKnuthElements(LayoutContext context,
int alignment)
Get a sequence of KnuthElements representing the content
of the node assigned to the LM.
|
java.util.List |
getNextKnuthElements(LayoutContext context,
int alignment,
LeafPosition restartPosition)
Get a sequence of KnuthElements representing the content
of the node assigned to the LM.
|
boolean |
handleOverflow(int milliPoints)
Whether this LM can handle horizontal overflow error messages (only a BlockContainerLayoutManager can).
|
protected boolean |
hasLeadingFence(boolean isNotFirst)
Line area is always considered to act as a fence.
|
boolean |
hasLineAreaDescendant()
Whether the FO handled by this layout manager has a descendant (including itself)
that will generate a line-area.
|
protected boolean |
hasTrailingFence(boolean isNotLast)
Line area is always considered to act as a fence.
|
void |
initialize()
initialize the layout manager.
|
boolean |
isRestartable()
Returns
true if this layout manager is able to re-generate its
Knuth elements after an IPD change. |
boolean |
mustKeepTogether() |
boolean |
mustKeepWithNext() |
boolean |
mustKeepWithPrevious() |
int |
negotiateBPDAdjustment(int adj,
KnuthElement lastElement)
Negotiate BPD adjustment.
