Type parameters

We have already discussed the typing system in haXe, but now, we are going to see the Type parameters. You may have already seen them in some languages, maybe under the name of Generics.

We will now see:

• The usage of Type parameters

• Using Type parameters with already created types

• Creating a type that makes use of them

• Creating an example

Let's continue discovering the typing system!

Usage of Type parameters

So far, you have only created functions that took some parameters with a defined type and returned a value with a defined type. You have always decided what these types were when creating your functions.

With Type parameters, it is possible to let the person use a class and decide what types will be used by some of its functions.

You may wonder why this is useful, and indeed, we have already used Type parameters in this book; remember how we said we were going to create an "Array of String"? Well, we have been using Type parameters at this moment.

In fact, Type parameters are like...
