java.lang.Objectorg.mule.util.generics.GenericTypeResolver
public abstract class GenericTypeResolver
Helper class for resolving generic types against type variables.
Mainly intended for usage within the framework, resolving method parameter types even when they are declared generically.
author: Spring
