Method Details

getType

@NonNull Type getType()

The original reflective type (Class, ParameterizedType, etc.)

getRawClass

@NonNull Class<?> getRawClass()

Raw class, with erasure (List.class for List<UUID>, etc.)

matchesClass

default @NonNull Boolean matchesClass(@NonNull Class<?> rawClass)

Returns:

true if getRawClass() matches the provided rawClass (no subtype/parameter checks), false otherwise.

matchesParameterizedType

default @NonNull Boolean matchesParameterizedType(@NonNull Class<?> rawClass,
 Class<?> @Nullable ... typeArguments)

Does this instance match the given raw class and its parameterized type arguments?

For example, invoke matchesParameterizedType(List.class, UUID.class) to determine "is this type a List<UUID>?"

isList

default @NonNull Boolean isList()

getListElementType

default @NonNull Optional<TargetType> getListElementType()

isSet

default @NonNull Boolean isSet()

getSetElementType

default @NonNull Optional<TargetType> getSetElementType()

isMap

default @NonNull Boolean isMap()

getMapKeyType

default @NonNull Optional<TargetType> getMapKeyType()

getMapValueType

default @NonNull Optional<TargetType> getMapValueType()

isArray

default @NonNull Boolean isArray()

getArrayComponentType

default @NonNull Optional<TargetType> getArrayComponentType()

getTypeArguments

@NonNull List<TargetType> getTypeArguments()

All type arguments wrapped (empty for raw/non-parameterized).

static @NonNull TargetType of(@NonNull Type type)
