Obtain per-character (glyph) bidi levels over a specified subsequence.
If word has been reversed, then the subsequence is over the reversed word.
start - starting (inclusive) index of subsequenceend - ending (exclusive) index of subsequencepublic int bidiLevelAt(int position)
Obtain per-character (glyph) level at a specified index position.
If word has been reversed, then the position is relative to the reversed word.

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.

levelpublic void reverse(boolean mirror)
Reverse characters and corresponding per-character levels and glyph position adjustments.
mirror - if true, then perform mirroring if mirrorred characterspublic void mirror()
Perform mirroring on mirrorable characters.
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.
