TypeVariable will be unwrapped to the type argument resolved form the class
hierarchy. This may be something other than a simple Class if the type argument is a ParameterizedType for
instance (e.g. List<E>; List<Map<Long, String>>, E would be returned as a ParameterizedType with the raw
type Map and type arguments Long and String.resolve in interface GenericsResolvertype - the generic type (ParameterizedType, GenericArrayType, WildcardType, TypeVariable) to be resolvedcontainingType - the type which hispublic Class asClass(Type actualType)
TypeVariable the first bound is returned. If your type variable extends multiple interfaces that information
is lost.
WildcardType the first lower bound is returned. If the wildcard is defined with upper bounds
then Object is returned.asClass in interface GenericsResolveractualType - a Class, ParameterizedType, GenericArrayType5.6.4 - Copyright © 2003-2021 The Apache Software Foundation.
