Here is something I've been wanting to know for a long time now.
Is it possible to pass an object but first call a void method on that object in the same line? It is quite hard to explain but I'll give an example:
I'm using a Vector
object from a third party API, it just holds 3 coordinates, and I'm passing it into a made up setLocation(Vector)
method; but first I want to add 3 to the Y value of that Vector which is done by Vector#addY(3f);
So is it possible to do this on the same line?
setLocation(new Vector(0f,4f,0f).addY(3));
I think that should explain what I mean.
If you can change addY() to "return this" then you're in business.
Since it is a third party API maybe you just need a helper function:
Vector makeAndSetupVector(float f1, float f2, float f3, int y) {
Vector vect = new Vector(f1, f2, f3);
vect.addY(y);
return vect;
}
Now you can do:
setLocation(makeAndSetupVector(0f, 4f, 0f, 3));
