public final class Types
Static methods for working with types.
| Method Summary | |
|---|---|
static GenericArrayType |
arrayOf(Type componentType)
Returns an array type whose elements are all instances of componentType. |
static ParameterizedType |
listOf(Type elementType)
Returns a type modelling a List whose elements are of type
elementType. |
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. |
static ParameterizedType |
newParameterizedType(Type rawType,
Type... typeArguments)
Returns a new parameterized type, applying typeArguments to
rawType. |
static ParameterizedType |
newParameterizedTypeWithOwner(Type ownerType,
Type rawType,
Type... typeArguments)
Returns a new parameterized type, applying typeArguments to
rawType and enclosed by ownerType. |
static ParameterizedType |
providerOf(Type providedType)
Returns a type modelling a Provider that provides elements of type
elementType. |
static ParameterizedType |
setOf(Type elementType)
Returns a type modelling a Set whose elements are of type
elementType. |
static WildcardType |
subtypeOf(Type bound)
Returns a type that represents an unknown type that extends bound. |
static WildcardType |
supertypeOf(Type bound)
Returns a type that represents an unknown supertype of bound. |

public static ParameterizedType newParameterizedType(Type rawType,
Type... typeArguments)
typeArguments to
rawType. The returned type does not have an owner type.
serializable parameterized type.
public static ParameterizedType newParameterizedTypeWithOwner(Type ownerType,
Type rawType,
Type... typeArguments)
typeArguments to
rawType and enclosed by ownerType.
serializable parameterized type.public static GenericArrayType arrayOf(Type componentType)
componentType.
serializable generic array type.public static WildcardType subtypeOf(Type bound)
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)
bound. For
example, if bound is String.class, this returns ?
super String.
public static ParameterizedType listOf(Type elementType)
List whose elements are of type
elementType.
serializable parameterized type.public static ParameterizedType setOf(Type elementType)
Set whose elements are of type
elementType.
serializable parameterized type.
public static ParameterizedType mapOf(Type keyType,
Type valueType)
Map whose keys are of type
keyType and whose values are of type valueType.
serializable parameterized type.public static ParameterizedType providerOf(Type providedType)
Provider that provides elements of type
elementType.
serializable parameterized type.
