List of usage examples for org.apache.commons.lang.reflect MethodUtils invokeExactMethod
public static Object invokeExactMethod(Object object, String methodName, Object[] args) throws NoSuchMethodException, IllegalAccessException, InvocationTargetException
Invoke a method whose parameter types match exactly the object types.
This uses reflection to invoke the method obtained from a call to getAccessibleMethod().
