Operator: ToIterable

[benjchristensen]

We already from toObservable(Iterable)/from(Iterable) ... add the reverse blocking toIterable() similar to the non-blocking toList() which already exists.

ToEnumerable from C#: http://msdn.microsoft.com/en-us/library/hh212132(v=vs.103).aspx

ToEnumerable don't seems to be different from ToList.

First one returns IObservable<IList<TSource>> second one IEnumerable<TSource>.

The toList operator is non-blocking as it returns Observable<List> whereas to Iterable is blocking and returns Iterable.

The key difference is non-blocking versus blocking, otherwise yes, they behave similarly.

The other difference though is that toList will wait until the observable sequence is onCompleted() and then emit the List whereas toIterable will buffer but start allowing take() to be called immediately as each onNext() value is emitted.

Merged.

By the way ... a key difference in Java is that Iterable is not an equal dual with Observable whereas IEnumerable is a dual to IObservable in .Net where both have extension methods with all the functional operators.

Since Java doesn't have extension methods we can't do that here. At best we could have another parallel framework for wrapping an Iterable.
