Public Methods

public static GenericArrayType arrayOf (Type componentType)

Returns an array type whose elements are all instances of componentType.

Returns

public static ParameterizedType listOf (Type elementType)

Returns a type modelling a List whose elements are of type elementType.

Returns

public static ParameterizedType mapOf (Type keyType, Type valueType)

Returns a type modelling a Map whose keys are of type keyType and whose values are of type valueType.

Returns

public static ParameterizedType newParameterizedType (Type rawType, Type... typeArguments)

Returns a new parameterized type, applying typeArguments to rawType. The returned type does not have an owner type.

Returns

public static ParameterizedType newParameterizedTypeWithOwner (Type ownerType, Type rawType, Type... typeArguments)

Returns a new parameterized type, applying typeArguments to rawType and enclosed by ownerType.

Returns

public static ParameterizedType providerOf (Type providedType)

Returns a type modelling a Provider that provides elements of type elementType.

Returns

public static ParameterizedType setOf (Type elementType)

Returns a type modelling a Set whose elements are of type elementType.

Returns

public static WildcardType subtypeOf (Type bound)

Returns a type that represents an unknown type that extends bound. For example, if bound is CharSequence.class, this returns ? extends CharSequence. If bound is Object.class, this returns ?, which is shorthand for ? extends Object.

public static WildcardType supertypeOf (Type bound)

Returns a type that represents an unknown supertype of bound. For example, if bound is String.class, this returns ? super String.
