> Enhancements on the Generator API
> ---------------------------------
>
> Key: FUNCTOR-14
> URL: https://issues.apache.org/jira/browse/FUNCTOR-14
> Project: Commons Functor
> Issue Type: Improvement
> Reporter: Bruno P. Kinoshita
> Assignee: Bruno P. Kinoshita
> Priority: Minor
>
> Apparently, the Generator API in [functor] was created based on Python
> generators. However, there is room for enhancements in the current
> implementation.
> The Generator interface contains methods to stop its execution. However not
> all generators are necessarily 'stoppable'. Maybe we could move this behavior
> to a separate interface.
> The parameters passed to a generator (from, to, step) are the same that, in
> Python, can be used to create a Range. Ranges are used in many examples of
> Generators in Python. We could include Ranges in [functor] and utilize them
> in Generators. It would be good if we could include/exclude the Range
> boundary values, i.e. we could create a Range 0..2, and define 0 or 2, as
> being either inclusive or exclusive.
> Among the current generators, there is one for Integer's, and another one for
> Long's. We could create generators for other types too (e.g.: Char, Date,
> Double, Float, ...).
> Another feature usually related to Generators in Python is the yield
> statement. There are some API's in Java that provide a yield implementation.
> This is not entirely necessary, but could be convenient to include it to
> [functor] too, combined with Generators. Maybe in [functor] we could create a
> YieldProcedure. This way, the Generator would yield its values to this
> procedure. Just food for thought.
> This issue is quite vague, so feel free to add comments, or criticize. This
> way we can achieve a common consensus on a new and awesome Generator API for
> [functor]. No hard feelings :-)
> Cheers
