org.apache.tamaya.TypeLiteral<T>

Type Parameters:

T - the type, including all type parameters

All Implemented Interfaces:

Serializable

public class TypeLiteral<T>
extends Object
implements Serializable

Class for instantiation of objects that represent parameterized types with current parameters.

An createObject that represents a parameterized type may be obtained by subclassing TypeLiteral.
