Xiidref :
I would like to create a class that can handle an undefined number of generic type is that even possible with java ?
The idea behind this weird question is to create a tuple with a size fixed in his contructor where each element at position i is of the type at the pos i%numberoftype.
Joachim Sauer :
No, types in Java have a fixed number of type parameters.
The closest you could get is to have a (finite) number of related classes:
class Tuple1<A> { ... }
class Tuple2<A, B> { ... }
class Tuple3<A, B, C> { ... }
And then provide a common class with factory methods:
class Tuples {
static <A> Tuple1<A> of(A a) { ... }
static <A, B> Tuple2<A,B> of(A a, B b) { ... }
static <A, B, C> Tuple1<A,B,C> of(A a, B b, C c) { ... }
}
