### Method Detail

#### getWord

    public String getWord()

Returns:
  Returns the word.

#### getLetterAdjustArray

    public int[] getLetterAdjustArray()

Returns:
  the array of letter adjust widths

#### getBidiLevels

    public int[] getBidiLevels()

Obtain per-character (glyph) bidi levels.

Returns:
  a (possibly empty) array of levels or null (if none resolved)

#### getBidiLevels

    public int[] getBidiLevels(int start,
                               int end)

Obtain per-character (glyph) bidi levels over a specified subsequence.

If word has been reversed, then the subsequence is over the reversed word.

Parameters:
  `start` - starting (inclusive) index of subsequence
  `end` - ending (exclusive) index of subsequence
Returns:
  a (possibly null) array of per-character (glyph) levels over the specified sequence

#### bidiLevelAt

Obtain per-character (glyph) level at a specified index position.

If word has been reversed, then the position is relative to the reversed word.

Parameters:
  `position` - the index of the (possibly reversed) character from which to obtain the level
Returns:
  a resolved bidirectional level or, if not specified, then -1

#### collectInlineRuns

    public List collectInlineRuns(List runs)

Description copied from class: `InlineArea`
Collection bidi inline runs.

Overrides:
  `collectInlineRuns` in class `InlineArea`
Parameters:
  `runs` - current list of inline runs
Returns:
  modified list of inline runs, having appended new run

#### getGlyphPositionAdjustments

    public int[][] getGlyphPositionAdjustments()

Obtain per-character (glyph) position adjustments.

Returns:
  a (possibly empty) array of adjustments, each having four elements, or null if no adjustments apply

#### glyphPositionAdjustmentsAt

    public int[] glyphPositionAdjustmentsAt(int position)

Obtain per-character (glyph) position adjustments at a specified index position.

If word has been reversed, then the position is relative to the reversed word.

Parameters:

#### isReversed

    public boolean isReversed()

Determined if word has been reversed (in relation to original logical order).

If a word is reversed, then both its characters (glyphs) and corresponding per-character levels are in reverse order.

Note: this information is used in order to process non-spacing marks during rendering as well as provide hints for caret direction.

Returns:
  true if word is reversed
