Constructor Summary
`AbstractTextArea()` Default constructor
`AbstractTextArea(int stretch, int shrink, int adj)` Constructor with extra parameters: create a TextAdjustingInfo object

Method Summary
`boolean` | `applyVariationFactor(double variationFactor, int lineStretch, int lineShrink)` recursively apply the variation factor to all descendant areas
`int` | `getBaselineOffset()` Get baseline offset, i.e.
`int` | `getTextLetterSpaceAdjust()` Get text letter space adjust.

`void` | `setBaselineOffset(int baselineOffset)` Set the baseline offset.
`void` | `setSpaceDifference(int spaceDiff)` Set the difference between optimal width of a space and default width of a space according to the font; this part of the space adjustment is fixed and must not be multiplied by the variation factor.
`void` | `setTextLetterSpaceAdjust(int textLetterSpaceAdjust)` Set text letter space adjust.

Constructor Detail

### AbstractTextArea

    public AbstractTextArea()

  Default constructor

### AbstractTextArea

    public AbstractTextArea(int stretch,
                            int shrink,
                            int adj)

  Constructor with extra parameters: create a TextAdjustingInfo object

Parameters:
  `stretch` - the available stretch of the text
  `shrink` - the available shrink of the text
  `adj` - the current adjustment of the area

Method Detail

### getTextWordSpaceAdjust

    public int getTextWordSpaceAdjust()

  Get text word space adjust.

  Returns:
    the text word space adjustment

### setTextWordSpaceAdjust

    public void setTextWordSpaceAdjust(int textWordSpaceAdjust)

  Set text word space adjust.

  Parameters:
    `textWordSpaceAdjust` - the text word space adjustment

### getTextLetterSpaceAdjust

    public int getTextLetterSpaceAdjust()

  Get text letter space adjust.

  Returns:
    the text letter space adjustment

### setTextLetterSpaceAdjust

    public void setTextLetterSpaceAdjust(int textLetterSpaceAdjust)

  Set text letter space adjust.

  Parameters:
    `textLetterSpaceAdjust` - the text letter space adjustment

### setSpaceDifference

    public void setSpaceDifference(int spaceDiff)

  Set the difference between optimal width of a space and default width of a space according to the font; this part of the space adjustment is fixed and must not be multiplied by the variation factor.

  Parameters:
    `spaceDiff` - the space difference

### applyVariationFactor

    public boolean applyVariationFactor(double variationFactor,
                                        int lineStretch,
                                        int lineShrink)

  recursively apply the variation factor to all descendant areas

  Overrides:

    `lineStretch` - the total stretch of the line
    `lineShrink` - the total shrink of the line
  Returns:
    true if there is an UnresolvedArea descendant

### getBaselineOffset

    public int getBaselineOffset()

  Get baseline offset, i.e. the distance from the before edge of this area to the nominal baseline.

  Returns:
    the baseline offset

### setBaselineOffset

    public void setBaselineOffset(int baselineOffset)
