const std::string &  name,

Member Function Documentation

◆ OnEventInit()

virtual void ClientProtocol::EventHook::OnEventInit ( const ClientProtocol::Event ev)

Called exactly once before an event is sent to any user. The default implementation doesn't do anything.

evEvent being sent to one or more users.

◆ OnPreEventSend()

virtual ModResult ClientProtocol::EventHook::OnPreEventSend ( LocalUser user,
const ClientProtocol::Event ev,
ClientProtocol::MessageList &  messagelist 
pure virtual

Called for each user that may receive the event. The hook may alter the messages sent to the user and decide whether further hooks should be executed.

userUser the message list is being prepared to be sent to.
evEvent associated with the messages.
messagelistList of messages to send to the user. The hook can alter this in any way it sees fit, for example it can replace messages, add new messages, etc. The list must not be empty when the method returns.
MOD_RES_PASSTHRU to run hooks after the called hook or if no hooks are after the called hook, send the messages in messagelist to the user. MOD_RES_DENY to not send any messages to the user and to not run other hooks, MOD_RES_ALLOW to send the messages in messagelist to the user and to not run other hooks.
