public TableCellLayoutManager(TableCell node,
                              PrimaryGridUnit pgu)
Create a new Cell layout manager.

node - table-cell FO for which to create the LM
pgu - primary grid unit for the cell
Method Detail

getTableCell

public TableCell getTableCell()
Returns:
the table-cell FO

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()

getTable

public Table getTable()
Returns:
the table owning this cell

getIPIndents

protected int getIPIndents()
Overrides:
getIPIndents in class BlockStackingLayoutManager
Returns:
the sum of start-indent and end-indent
See Also:
BlockStackingLayoutManager.getIPIndents()

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
Parameters:
context - the LayoutContext used to store layout information
alignment - the desired text alignement
Returns:
the list of KnuthElements
See Also:
LayoutManager

setYOffset

public void setYOffset(int off)
Set the y offset of this cell. This offset is used to set the absolute position of the cell.

Parameters:
off - the y direction offset

setXOffset

public void setXOffset(int off)
Set the x offset of this cell (usually the same as its parent row). This offset is used to determine the absolute position of the cell.

Parameters:
off - the x offset

setInRowIPDOffset

public void setInRowIPDOffset(int off)
Set the IPD offset of this cell inside the table-row. This offset is used to determine the absolute position of the cell.

Parameters:
off - the IPD offset

setContentHeight

public void setContentHeight(int h)
Set the content height for this cell. This method is used during addAreas() stage.

Parameters:
h - the height of the contents of this cell

setRowHeight

public void setRowHeight(int h)
Set the row height that contains this cell. This method is used during addAreas() stage.

Parameters:
h - the height of the row

addAreas

public void addAreas(PositionIterator parentIter,
                     LayoutContext layoutContext,
                     int[] spannedGridRowHeights,
                     int startRow,
                     int endRow)
Add the areas for the break points. The cell contains block stacking layout managers that add block areas.

In the collapsing-border model, the borders of a cell that spans over several rows or columns are drawn separately for each grid unit. Therefore we must know the height of each grid row spanned over by the cell. Also, if the cell is broken over two pages we must know which spanned grid rows are present on the current page.

Parameters:
parentIter - the iterator of the break positions
layoutContext - the layout context for adding the areas
spannedGridRowHeights - in collapsing-border model for a spanning cell, height of each spanned grid row
startRow - first grid row on the current page spanned over by the cell, inclusive
endRow - last grid row on the current page spanned over by the cell, exclusive

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

addChildArea

public void addChildArea(Area childArea)
Add the child to the cell block area.

Specified by:
addChildArea in interface LayoutManager
Overrides:
addChildArea in class BlockStackingLayoutManager
Parameters:
childArea - the child to add to the cell

resetPosition

public void resetPosition(Position resetPos)
Reset the position of the layout.

Specified by:
resetPosition in interface LayoutManager
Overrides:
resetPosition in class AbstractLayoutManager
Parameters:
resetPos - the position to reset to
See Also:
LayoutManager.resetPosition(Position)
