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.

`Object`	`getAttribute(AttributedCharacterIterator.Attribute attribute)` Get the value of the named attribute for the current character.
`Map`	`getAttributes()` Returns a map with the attributes defined on the current character.
`int`	`getBeginIndex()` Returns the start index of the text.
`int[]`	`getCharMap()`
`int`	`getEndIndex()` Returns the end index of the text.
`int`	`getIndex()` Returns the current index.
`int`	`getRunLimit()` Get the index of the first character following the run with respect to all attributes containing the current character.
`int`	`getRunLimit(AttributedCharacterIterator.Attribute attribute)` Get the index of the first character following the run with respect to the given attribute containing the current character.
`int`	`getRunLimit(Set attributes)` Get the index of the first character following the run with respect to the given attributes containing the current character.

`int`	`getRunStart(AttributedCharacterIterator.Attribute attribute)` Get the index of the first character of the run with respect to the given attribute containing the current character.
`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.
