Trigring MessageDeleteEvent

[erlichsefi]

it's no clear which parameters i need to write in the config file to trigger an MessageDeleteEvent.
i have tried ::
Events2.class = MessageDeleteEvent
Events2.interval = 10
Events2.size = 500k
Events2.hosts = 2,3
Events2.id=*

but i'm geting :
Can't start: error in configuration file(s)
Class 'input.MessageDeleteEvent' doesn't have a suitable constructor

some HELP?

There is no generator for message deletion events, but you can take a look at input/MessageEventGenerator to see how to build one. The other option is to create a file with the message deletion events and use the ExternalEventsQueue to trigger them in the simulation.

is there any other way to simulate a packet drop between two hosts?

[tk721]

Messages are not dropped between hosts. Each host maintains a buffer of the messages it is carrying and can remove messages from it at arbitrary times. See the DTNHost.deleteMessage() method.

does DTNHost.deleteMessage() remove message before Application.public Message handle(Message m, DTNHost host) () get them?

edit.
i can see that i can delete the messages that pass Application.public Message handle(Message m, DTNHost host) () . but if i want to delete message before that?
