Method Detail

findMethod

public java.lang.reflect.Method findMethod(java.lang.String name,
                                           java.lang.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.

Parameters:

name - name of the method.

params - The parameters for the method.

Returns:

Method.

Throws:

MethodMap.AmbiguousException - in case of an error.

getPublicMethod

public static java.lang.reflect.Method getPublicMethod(java.lang.reflect.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.
