- - org.gradle.api.reflect.TypeOf<T>

- Type Parameters:
    `T` - Parameterized type

      public abstract class TypeOf<T>
      extends Object

  Provides a way to preserve high-fidelity `Type` information on generic types. Capture a generic type with an anonymous subclass. For example:

    - #### typeOf

          public static <T> TypeOf<T> typeOf​(Class<T> type)

      Creates an instance of TypeOf for the given Class.

      Parameters:
        `type` - the Class
      Returns:
        the TypeOf that captures the generic type of the given Class

    - #### typeOf

          public static <T> TypeOf<T> typeOf​(Type type)

      Creates an instance of TypeOf for the given Type.
      Type Parameters:
        `T` - the parameterized type of the given Type
      Parameters:
        `type` - the Type
      Returns:
        the TypeOf that captures the generic type of the given Type

    - #### parameterizedTypeOf

          public static TypeOf<?> parameterizedTypeOf​(TypeOf<?> parameterizedType,
                                                      TypeOf<?>... typeArguments)

      Constructs a new parameterized type from a given parameterized type definition and an array of type arguments. For example, `parameterizedTypeOf(new TypeOf<List<?>>() {}, new TypeOf<String>() {})` is equivalent to `new TypeOf<List<String>>() {}`, except both the parameterized type definition and type arguments can be dynamically computed.
      Parameters:
        `parameterizedType` - the parameterized type from which to construct the new parameterized type
        `typeArguments` - the arguments with which to construct the new parameterized type
