Member Function Documentation

- (id) advanceBy:

(int)

count

Advance or reverse the iterator by a given number of positions.

This has the effect of advancing or reversing the underlying target iterator by the negation of count.

Parameters:

count

the number of positions to move the iterator, either forward or backward

Returns:

a reference to this iterator

- (id) copy

Make a copy of this iterator.

Returns:

a copy of this iterator

Reimplemented from OLReverseBidiIterator.

- (BOOL) isEqual:

(id)

object

Return whether this object is equal to another one.

Parameters:

object

the object to test

Returns:

YES if the iterator is equal to the object, NO if not
