Re: [ns] Drop packet!!!!!

2011-03-17 Thread Teerawat@UBC 

Hi Mohammed,

That's correct. Only the object whose class derives from class Connector can 
call the function drop(p). However, there are a lot of class like this, e.g., 
queues, agents.

 Hi,
 I've been reading the below blog :

 I found this sentence Note that drop(p) is a function of class Connector,
 and therefore must be invoked from within the scope of class Connector.
 
 Does this mean I can't call the drop from outside connector. In other words,
 If I want to call drop I have to create object from connector class then
 call drop???
 
 
 Please help me on this issue?
