deferred class ITERATOR [E_]
Summary
Class invariant
Overview
Features
{ANY}
  • is_valid: BOOLEAN
  • start
    Positions the iterator to the first object in the aggregate to be traversed.
  • is_off: BOOLEAN
    Returns True when there are no more objects in the sequence.
  • item: E_
    Returns the object at the current position in the sequence.
  • next
    Positions the iterator to the next object in the sequence.
Check that the underlying traversable has not changed
