Event

A multicast list of void delegate(T...) handlers.

Add handlers with ~=, invoke them all with fire, and remove one with disconnect. Firing with no registered handlers is a no-op. Handlers are invoked in registration order.

struct Event (

T...

) {

typeof(this) opOpAssign(void delegate(T) handler);

void connect(void delegate(T) handler);

void disconnect(void delegate(T) handler);

void fire(T args);

size_t length();

void clear();

}

Functions

clear void clear(): Remove all handlers.
connect void connect(void delegate(T) handler): Subscribe a handler (named-method equivalent of ~=).
disconnect void disconnect(void delegate(T) handler): Remove a previously-subscribed handler. Unknown handlers are ignored.
fire void fire(T args): Invoke every subscribed handler, in order, with the given arguments.
length size_t length(): Number of currently-subscribed handlers.
opOpAssign typeof(this) opOpAssign(void delegate(T) handler): Subscribe a handler: event ~= &handler.
