Modifier and Type	Method	Description
static Class<? extends Enum<?>>	asEnumClass(Type valueType)	Return the enum class for this type taking into account wildcard type.
static Class<?>	getMapKeyType(Type genericType)	Return the type of the map key.
static Type	getMapKeyTypeRaw(Type genericType)	Return the raw type of the map key (first type argument).
static Class<?>[]	getParams(Class<?> cls, Class<?> matchRawType)
static Type	getValueType(Type collectionType)	Return the value type of a collection type (list, set, map values).
static boolean	isEnumType(Type valueType)	Return true if the type is an enum.
static Class<?>	resolveCollectionTarget(Type typeArg)	Return the element class for a collection or map type argument (handles Class, ParameterizedType raw, and Kotlin-generated wildcard upper bounds).
static Class<?>	resolveToClass(Type type)	Return the raw Class for a Type, handling Class, ParameterizedType, and WildcardType.
static Type	resolveType(Type type, Map<TypeVariable<?>, Type> typeMap)	Resolve a Type through the given type-variable map, recursively substituting any bound TypeVariables and rebuilding ParameterizedTypes whose arguments changed.
static Map<TypeVariable<?>, Type>	typeVariableMap(Class<?> targetType)	Return the full map of TypeVariable to resolved Type for the given class and its entire superclass/interface hierarchy.

public TypeReflectHelper()

Method Details

typeVariableMap

public static Map<TypeVariable<?>, Type> typeVariableMap(Class<?> targetType)

Return the full map of TypeVariable to resolved Type for the given class and its entire superclass/interface hierarchy. Used to resolve generic field types in mapped superclasses.

getParams

public static Class<?>[] getParams(Class<?> cls,
 Class<?> matchRawType)

asEnumClass

public static Class<? extends Enum<?>> asEnumClass(Type valueType)

Return the enum class for this type taking into account wildcard type.

isEnumType

public static boolean isEnumType(Type valueType)

Return true if the type is an enum.

getMapKeyType

public static Class<?> getMapKeyType(Type genericType)

Return the type of the map key.

getMapKeyTypeRaw

public static Type getMapKeyTypeRaw(Type genericType)

Return the raw type of the map key (first type argument).

getValueType

public static Type getValueType(Type collectionType)

Return the value type of a collection type (list, set, map values).

resolveToClass

public static Class<?> resolveToClass(Type type)

Return the raw Class for a Type, handling Class, ParameterizedType, and WildcardType. Returns null when the raw class cannot be determined.

resolveCollectionTarget

public static Class<?> resolveCollectionTarget(Type typeArg)

Return the element class for a collection or map type argument (handles Class, ParameterizedType raw, and Kotlin-generated wildcard upper bounds).

resolveType

public static Type resolveType(Type type,
 Map<TypeVariable<?>, Type> typeMap)

Resolve a Type through the given type-variable map, recursively substituting any bound TypeVariables and rebuilding ParameterizedTypes whose arguments changed.
