- org.codelibs.jhighlight.fastutil.chars.AbstractCharIterator
- - org.codelibs.jhighlight.fastutil.chars.AbstractCharBidirectionalIterator

All Implemented Interfaces:

Iterator<Character>, BidirectionalIterator<Character>, CharBidirectionalIterator, CharIterator, ObjectBidirectionalIterator<Character>, ObjectIterator<Character>

Direct Known Subclasses:

AbstractCharListIterator, CharIterators.UnmodifiableBidirectionalIterator
```
public abstract class AbstractCharBidirectionalIterator
extends AbstractCharIterator
implements CharBidirectionalIterator
```
An abstract class facilitating the creation of type-specific bidirectional iterators.
To create a type-specific bidirectional iterator, besides what is needed for an iterator you need both a method returning the previous element as primitive type and a method returning the previous element as an object. However, if you inherit from this class you need just one (anyone).
This class implements also a trivial version of back(int) that uses type-specific methods.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`back(int n)`	This method just iterates the type-specific version of `previous()` for at most `n` times, stopping if `BidirectionalIterator.hasPrevious()` becomes false.
`Character`	`previous()`	Delegates to the corresponding type-specific method.
`char`	`previousChar()`	Delegates to the corresponding generic method.

    Delegates to the corresponding generic method.
    
    Specified by:
    
    previousChar in interface CharBidirectionalIterator
    
    Returns:
    
    the previous element in the iteration.

```
public Character previous()
```
    Delegates to the corresponding type-specific method.
    
    Specified by:
    
    previous in interface BidirectionalIterator<Character>
    
    Returns:
    
    the previous element from the collection.
    
    See Also:
    
    ListIterator.previous()
  - back
```
public int back(int n)
```
    This method just iterates the type-specific version of previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.
    
    Specified by:
    
    back in interface CharBidirectionalIterator
    
    Specified by:
    
    back in interface ObjectBidirectionalIterator<Character>
    
    Parameters:
    
    n - the number of elements to skip back.
    
    Returns:
    
    the number of elements actually skipped.
