public interface CharBidirectionalIterator
extends CharIterator, ObjectBidirectionalIterator<Character>

Method Detail

previousChar

char previousChar()

Returns the previous element as a primitive type.

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

back

int back(int n)

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling BidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Specified by:

back in interface ObjectBidirectionalIterator<Character>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.
