Constructor Detail

### InlineArea

    public InlineArea()

  Default constructor for inline area.

### InlineArea

    protected InlineArea(int blockProgressionOffset,
                         int bidiLevel)

  Instantiate inline area.

  Parameters:

    `bidiLevel` - a resolved bidi level or -1

Method Detail

### getAdjustingInfo

    public InlineArea.InlineAdjustingInfo getAdjustingInfo()

  Returns:
    the adjustment information object

### setAdjustingInfo

    public void setAdjustingInfo(int stretch,
                                 int shrink,
                                 int adjustment)

  Create a new adjustment information object

  Parameters:
    `stretch` - the available space for stretching
    `shrink` - the available space for shrinking
    `adjustment` - space adjustment type

### setAdjustment

    public void setAdjustment(int adjustment)

  Modify the adjustment value in the adjustment information object

  Parameters:
    `adjustment` - the new adjustment value

### increaseIPD

    public void increaseIPD(int ipd)

  Increase the inline progression dimensions of this area. This is used for inline parent areas that contain mulitple child areas.

  Parameters:
    `ipd` - the inline progression to increase by

### setBlockProgressionOffset

    public void setBlockProgressionOffset(int blockProgressionOffset)

  Set the block progression offset of this inline area. This is used to set the offset of the inline area which is relative to the before edge of the parent area.

  Parameters:
    `blockProgressionOffset` - the offset

### getBlockProgressionOffset

    `ipdVariation` - the difference between new and old ipd

### collectInlineRuns

    public java.util.List collectInlineRuns(java.util.List runs)

  Collection bidi inline runs.

  Parameters:
    `runs` - current list of inline runs
  Returns:
    modified list of inline runs, having appended new run

### isAncestorOrSelf
