This is a generic class (like template classes in C++). This is a way to
build a set of classes parameterized by a type.
The most common use of these kinds of classes are containers. Instead of
using the same container class for storing Apples and Potatoes, you can
define a generic container that can manipulate Apples or Potatoes,
according to a type parameter : Container<Apple> will store Apples and
Container<Potatoes> will store Potatoes.
This allow to detect errors (like inserting a Potatoe into an Apples
container) at compilation time instead of getting an error at runtime.
You can find a more detailed explanation there :
