Interaction with JDK entities about cactoos HOT 15 CLOSED

@vssekorin The main constructor is code-free. But the secondary constructor can instanciate objects. Pay attention that instantiation doesn't execute any action (method executing or something like that). This will be performed later.

from cactoos.

E.g. java.lang.CharSequence interface might be used instead of org.cactoos.Text and then string consuming might be looks like
new UpperText("some java literal")
as java.lang.String already implements java.lang.CharSequence interface.

@Englishman What do you think to use a secondary constructor to it? Like:

public final class UpperText implements Text {
  public UpperText(final String string) {
    this(new StringAsText(string));
  }
  public UpperText(final Text origin) {
    this.origin = origin;
  }
}

from cactoos.

@Englishman I'm not managing this repo, remove the webhook or contact me in Slack //cc @yegor256

from cactoos.

if (new IsBlank(new StringAsText("java string")).asValue()) {
...
}
For me the both producing and consuming look a bit cumbersome and verbose. Is there any way to make JDK interaction smoothly?

It looks like part of the procedure.
My suggestion:

new CondProc<>(
    conditional,
    firstProcedure,
    secondProcedure
).apply(...);

and

Type object = new Ternary<>(
    conditional,
    firstFunction, //Func<Something1, Type>
    secondFuntion //Func<Something2, Type>
).apply(...);

But I'm not sure about this completely. We had to wait for @yegor256 reply.

from cactoos.

@vssekorin yes, I thought about the such approach but you suggestion is a substitute of Java lang standard if statement. So Cactoos will be kind of a framework but not a library then.

BTW here

new CondProc<>(
    conditional,
    firstProcedure,
    secondProcedure
).apply(...);

what are apply method params?

from cactoos.

It's OO primitives library, I have proposed OO analog if.

what are apply method params?

Type object = new Ternary<>(
    conditional, //Func.Pred<Some1>
    first, //Func<Some2, Type>
    second //Func<Some3, Type>
).apply(Some1 arg1, Some2 arg2, Some3 arg3);

(My example is wrong. I used it to explain the idea.)

from cactoos.

@yegor256 WDYT? Pls, share you strategical opinion here.

from cactoos.

@Englishman I think we should try to stay as far away from JDK "things" as we can. Otherwise, we will just create another Guava. That's why that Scalar and others. Of course, we can add implements Number to, say, LengthOfIterable, for extra convenience. Feel free to submit a PR.

from cactoos.

@fabriciofx What about Constructors Must Be Code-Free? I'm not sure that this is the right solution.

from cactoos.

@fabriciofx like your idea! At least, we'll have a cheap one-way of JDK interaction.

from cactoos.

@vssekorin @fabriciofx but look on this discussion.
#20 (comment)
It's not about new in ctors. It's about some code. WDYT?

Added separate issue #62 for this

from cactoos.

@Englishman I believe this issue no longer applies. We now have TextOf(CharSequence); we can also do new UpperText(Text) or new UpperText(() -> "your string"). Can we close this?

from cactoos.

@Englishman can we close this?

from cactoos.

@Englishman closing

from cactoos.

The job is not in WBS, won't close the order
