Member Function Documentation

nsISupports nsIForwardIterator::clone ( )

Create a new iterator pointing to the same position in the underlying container or sequence to which this iterator currently points.

The returned iterator is suitable for use in a subsequent call to |isEqualTo()| against this iterator.

Returns:
a new iterator pointing at the same position in the same underlying container or sequence as this iterator

Retrieve (and |AddRef()|) the element this iterator currently points to.

The result is undefined if this iterator currently points outside the useful range of the underlying container or sequence.

Returns:
a new reference to the element this iterator currently points to (if any)
boolean nsIForwardIterator::isEqualTo ( in nsISupports  anotherIterator)

Test if |anotherIterator| points to the same position in the underlying container or sequence.

The result is undefined if |anotherIterator| was not created by or for the same underlying container or sequence.

Parameters:
anotherIteratoranother iterator to compare against, created by or for the same underlying container or sequence
Returns:
true if |anotherIterator| points to the same position in the underlying container or sequence
void nsIForwardIterator::putElement ( in nsISupports  anElementToPut)

Put |anElementToPut| into the underlying container or sequence at the position currently pointed to by this iterator.

The iterator and the underlying container or sequence cooperate to |Release()| the replaced element, if any and if necessary, and to |AddRef()| the new element.

The result is undefined if this iterator currently points outside the useful range of the underlying container or sequence.

Parameters:
anElementToPutthe element to place into the underlying container or sequence

Advance this iterator to the next position in the underlying container or sequence.
