Class TypeLiteral<T>

  • Type Parameters:
    T - 
    public abstract class TypeLiteral<T>
extends java.lang.Object
    Supports inline instantiation of objects that represent parameterized types with actual type parameters. An object that represents any parameterized type may be obtained by subclassing TypeLiteral. 
      TypeLiteral<List<String>> stringListType = new TypeLiteral<List<String>>() {};
