wrf.IterWrapper

class wrf.IterWrapper(wrapped)

A wrapper class for generators and custom iterable classes that returns a new iterator to the start of the sequence when IterWrapper.__iter__() is called.

If the wrapped object is a generator, a copy of the generator is constructed and returned when IterWrapper.__iter__() is called. If the wrapped object is a custom type, then the copy.copy() is called and a new instance is returned. In both cases, the original iterable object is unchanged.

Note

Do not increment the wrapped iterable outside of this wrapper.

__init__(wrapped)

Parameters:wrapped (an iterable object) – Any iterable object that contains the __iter__ method.
