Class ArrayMaker<T>

java.lang.Object

rasmus_torkel.misc.ArrayMaker<T>

Type Parameters:

T -

Direct Known Subclasses:

ArrayMaker2D

public abstract class ArrayMaker<T>
extends java.lang.Object

This class is for creating arrays generically. In Java Generics, the type is not known at runtime, creating some complications when we need to create objects and arrays generically. The way this is solved in the Rasmus Torkel system is that generic classes that create arrays take a generic ArrayMaker. Every class that needs an ArrayMaker needs to have its own ArrayMaker subclass. An every subclass has a function for actually creating the array which is not generic.

It is strongly recommended that where possible, you declare each array maker in a public static final field called ARRAY_MAKER in the class for which it creates arrays. An anonymous inner class is a good way to do it.

There are separate subclasses for higher dimensions. If you require an array maker that also creates two dimensional arrays, than your ArrayMaker should be a subclass of ArrayMaker2D but still satisfy the conventions described in the previous paragraph.
