Little note for anyone that wants to emulate the behavior of foreach as close as possible in order to work with somewhat picky Traversable objects, without using foreach:
- Before starting the iteration, rewind() is called.
- For every iteration, the following methods are called on the iterator:
- valid()
- current()
- key()
- next()
Sounds like a silly thing to do put this way, but in my use case I needed to convert a Traversable database result cursor into a procedural-style cursor (hasNext + fetchArray) for backward compatibility, and the driver required every function to be called in the appropriate order.
