Interface Iterator

All Superinterfaces:

Block, Owner, Step

All Known Implementing Classes:

WhileAnyStep, WhileNotAnyStep, WhileNotStep, WhileStep

public interface Iterator
extends Block

An Iterator is a Block that conditionally repeats the nested Steps associated with the Block more than once (such as a Block that implements "while" or "for" functionality). This is a tagging interface only - it is useful to help Steps that implement "break" or "continue" type processing to detect whether they have been invoked correctly (nested inside an Iterator) or not.
