Class TypeOf<T>

java.lang.Object
org.gradle.api.reflect.TypeOf<T>
Type Parameters:
T - Parameterized type
@Incubating 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: 
   
   new TypeOf<NamedDomainObjectContainer<ArtifactRepository>>() {}

    • typeOf

      public static <T> TypeOf<T> typeOf(Class<T> type)
      Creates an instance of TypeOf for the given Class.
      Type Parameters:
      T - the parameterized type of 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
