All Implemented Interfaces:

```
public class BidiAttributedCharacterIterator
extends Object
implements AttributedCharacterIterator
```
An attributed character iterator that does the reordering of the characters for bidirectional text. It reorders the characters so they are in visual order. It also assigns a BIDI_LEVEL attribute to each character which can be used to split the reordered ACI into text runs based on direction. ie. characters in a text run will all have the same bidi level.

`int`	`getRunStart(Set attributes)` Get the index of the first character of the run with respect to the given attributes containing the current character.
`char`	`last()` Sets the position to getEndIndex()-1 (getEndIndex() if the text is empty) and returns the character at that position.
`static int`	`mirrorChar(int c)`
`char`	`next()` Increments the iterator's index by one and returns the character at the new index.
`char`	`previous()` Decrements the iterator's index by one and returns the character at the new index.
