Annotation Interface TypeCast

@Retention(CLASS) @Target(METHOD) public @interface TypeCast
Overrides the standard way of casting a certain type in a TypeSystem. This is useful for types where the guest language specific type cast can be implemented more efficiently than a direct cast. The annotated method must be contained in a TypeSystem annotated class. Type checks must conform to the following signature: public static Type as{TypeName}(Object value). The casted type must be a type declared in the TypeSystem.

If no TypeCast is declared then the type system implicitly uses a type cast that can be declared as follows: 

@TypeCast(Type.class)
public static Type asType(Object value) {
        return (Type) value;
}
