  Standard constructor

Method Detail

### findMethod

    public Method findMethod(String name,
                             Object[] params)
                      throws MethodMap.AmbiguousException

  Find a Method using the methodKey provided. Look in the methodMap for an entry. If found, it'll either be a CACHE_MISS, in which case we simply give up, or it'll be a Method, in which case, we return it. If nothing is found, then we must actually go and introspect the method from the MethodMap.

### getPublicMethod

    public static Method getPublicMethod(Method method)

  For a given method, retrieves its publicly accessible counterpart. This method will look for a method with same name and signature declared in a public superclass or implemented interface of this method's declaring class. This counterpart method is publicly callable.
  Parameters:
    `method` - a method whose publicly callable counterpart is requested.
  Returns:
    the publicly callable counterpart method. Note that if the parameter method is itself declared by a public class, this method is an identity function.
