Direct Known Subclasses:
Buffer.DefaultBufferIterator, Buffer.Range.RangeIterator, BufferWrapper.IteratorWrapper
Method Summary
abstract def add (a : A) : Unit
Inserts "a" after the iterator's cursor. If next was last called, "a" is inserted after the element returned. If previous was last called, "a" is inserted before the element returned.
abstract def set (a : A) : Unit
Sets the element before this iterator's cursor to "a." Replaces either the last element returned by "next" or, if previous was called, the next element that would be return by "previous."
