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

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

Returns:

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

matchesParameterizedType

@Nonnull
default Boolean matchesParameterizedType(@Nonnull
 Class<?> rawClass,
 @Nullable
 Class<?>... 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

@Nonnull
default Boolean isList()

getListElementType

@Nonnull
default Optional<TargetType> getListElementType()

isSet

@Nonnull
default Boolean isSet()

getSetElementType

@Nonnull
default Optional<TargetType> getSetElementType()

isMap

@Nonnull
default Boolean isMap()

getMapKeyType

@Nonnull
default Optional<TargetType> getMapKeyType()

getMapValueType

@Nonnull
default Optional<TargetType> getMapValueType()

isArray

@Nonnull
default Boolean isArray()

getArrayComponentType

@Nonnull
default Optional<TargetType> getArrayComponentType()

getTypeArguments

@Nonnull
List<TargetType> getTypeArguments()

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