Tuple project method

[Flavio Pompermaier]

Hi flinkers,

it happens very often to me that I have to output a reuse tuple that
basically is a subset of the data contained of the input tuple..do you
think it could be useful to add a project method to Tuple class?

So that to be able to write something like:

Tuple3<x,x,x> reuse = tuple.project(0,2,5)?

Best,
Flavio

Sorry, to be effective the project should also take in input the target
tuple itself :)

Tuple3<x,x,x> reuse = tuple.project(reuse, 0,2,5)?

It would be an interesting addition.

Such a method cannot be done fully type safe in Java, but that might be
okay, since it is user-code internal.
