ScalarOf.java:33-36: Continue implement class ScalarOf...

[0pdd]

The puzzle 1320-62e15acb from #1320 has to be resolved:

cactoos/src/main/java/org/cactoos/scalar/ScalarOf.java

Lines 33 to 36 in 1ef744e

	* @todo #1320:30min Continue implement class ScalarOf that takes various
	* objects such as a Supplier, Callable, etc and implement Scalar. Use it
	* to replace in all places where it is needed. Add tests for each of the
	* constructors.

The puzzle was created by marceloamadeu on 17-Apr-20.

Estimate: 30 minutes, role: DEV.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.

@paulodamaso/z please, pay attention to this issue

[0crat]

The job #1349 assigned to @Englishman/z, here is why; the budget is 30 minutes, see §4; please, read §8 and §9; if the task is not clear, read this and this; there will be no monetary reward for this job

[andreoss]

@paulodamaso If implemented this will make new ScalarOf(() -> value) syntax ambiguous, and will require explicit cast to either of Supplier, Callable or Scalar. Is this intended?

[0crat]

The architect of the project has changed; @paulodamaso/z is not at this role anymore; @victornoel/z is the architect now

[victornoel]

@0crat in

[victornoel]

@andreoss no, this is not intended, a solution would be to introduce various classes OfCallable, OfSupplier and Of would then take a Scalar I suppose.

[andreoss]

@victornoel
Why ScalarOf should accept Callable and Supplier?
As a functional interface Scalar matches both of them, it will make lambda notation unambiguous and requiring explicit casting.

Can we have ScalarOfCallable instead?

[victornoel]

@andreoss yes, very good point. The name you propose is good to me, let's go with that.

[victornoel]

@andreoss ha, you forgot to remove the todo when you put ScalarOf back. Please make another PR.
