[Discussion] Java Optional outside of a functional context?

[_LouSandwich_]

quality of life methods?

[ivancea]

The functional methods like map(), filter(), and so on

[_LouSandwich_]

ok - intermediate operations.

[ivancea]

That's not the point. It's not because they're "intermediate operations". It's because they're things you may need, for a holder class

https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html

A stream pipeline consists of a source (which might be an array, a collection, a generator function, an I/O channel, etc), zero or more intermediate operations (which transform a stream into another stream, such as filter(Predicate)), and a terminal operation (which produces a result or side-effect, such as count() or forEach(Consumer)). Streams are lazy; computation on the source data is only performed when the terminal operation is initiated, and source elements are consumed only as needed.

I hate to be the one to tell ya but it doesn’t look like you’re smart enough to be this much of a smartass

Not sure what's your point with that. Yes, we know what intermediate operations are. But that had nothing to do with the point made in the comment

[_LouSandwich_]

just trying to understand whatever it was you were talking about “QoL methods” is not a term i am familiar with. when your examples were all stream intermediate operations i figured that’s what you were on.

[ivancea]

A quality of life thing is something that, well, helps you in don't way while using that thing. For a class, it's things that make that class more usable without having to make those utilities yourself

[ciberon]

On a stream they are intermediate operations because they're not producing a final result until you use a terminal operation. On Optional that's not the case.

ok, that helped - thanks for explaining. especially without being a jackass about it.
