Detailed Description

A user event.

The Event object is an event as send by TCPConnect::send or received by EventListener and given to your callbacks through EventConsumer.

Event are basically a "named Packet", where Packet contain the data you want to send / you just received.

//Create an event
Event event("hit_monster", make_packet(damage));
//Send it
//Extract data from an event (make a mutable copy)
std::string event_name = event.get_name();
Packet packet = event.get_packet();

Member Function Documentation

ByteArray SedNL::Event::get_header ( ) const

Compute the binary header of an event.

Low level function, used by the implementation.

You probably don't want to use it.

The binary header.
const std::string & SedNL::Event::get_name ( ) const

Return the event name.

Notice it's actualy a const reference to the handler. Make a copy if you expect the event to die before the string.

A handler to the event name.

Definition at line 54 of file Event.ipp.

const Packet & SedNL::Event::get_packet ( ) const

Return a reference to the packet handled.

Once this event is destructed, the packet will be destructed and the reference invalid.

The currently handled packet.

Definition at line 59 of file Event.ipp.

ByteArray SedNL::Event::pack ( ) const

Compute a binary string representing the event.

Low level function. Return the concatenated value of Event::get_header() and Packet::get_data().

The serialised event as a binary string.
void SedNL::Event::swap ( Event event)

Swap two events.

Swap the content of event with the content of the current event.

[in,out]eventto swap.
