bool Redirect::CheckTimeStamp (  time_t  theirs, time_t  ours, const std::string &  their_param, const std::string &  our_param, chanrec *  channel )  [inline, virtual]

If your mode needs special action during a server sync to determine which side wins when comparing timestamps, override this function and use it to return true or false. The default implementation just returns true if theirs < ours. This will only be called for non-listmodes with parameters, when adding the mode and where theirs == ours (therefore the default implementation will always return false). Parameters: theirs  The timestamp of the remote side ours  The timestamp of the local side their_param  Their parameter if the mode has a parameter our_param  Our parameter if the mode has a parameter channel  The channel we are checking against Returns: True if the other side wins the merge, false if we win the merge for this mode. Reimplemented from ModeHandler. Definition at line 36 of file m_redirect.cpp. { /* When TS is equal, the alphabetically later one wins */ return (their_param < our_param); }

ModePair Redirect::ModeSet (  userrec *  source, userrec *  dest, chanrec *  channel, const std::string &  parameter )  [inline, virtual]

When a remote server needs to bounce a set of modes, it will call this method for every mode in the mode string to determine if the mode is set or not. Parameters: source  of the mode change, this will be NULL for a server mode dest  Target user of the mode change, if this is a user mode channel  Target channel of the mode change, if this is a channel mode parameter  The parameter given for the mode change, or an empty string Returns: The first value of the pair should be true if the mode is set with the given parameter. In the case of permissions modes such as channelmode +o, this should return true if the user given as the parameter has the given privilage on the given channel. The string value of the pair will hold the current setting for this mode set locally, when the bool is true, or, the parameter given. This allows the local server to enforce our locally set parameters back to a remote server. Reimplemented from ModeHandler. Definition at line 28 of file m_redirect.cpp. References chanrec::GetModeParameter(), and chanrec::IsModeSet(). { if (channel->IsModeSet('L')) return std::make_pair(true, channel->GetModeParameter('L')); else return std::make_pair(false, parameter); }

ModeAction Redirect::OnModeChange (  userrec *  source, userrec *  dest, chanrec *  channel, std::string &  parameter, bool  adding )  [inline, virtual]

Called when a mode change for your mode occurs. Parameters: source  Contains the user setting the mode. dest  For usermodes, contains the destination user the mode is being set on. For channelmodes, this is an undefined value. channel  For channel modes, contains the destination channel the modes are being set on. For usermodes, this is an undefined value. parameter  The parameter for your mode, if you indicated that your mode requires a parameter when being set or unset. Note that if you alter this value, the new value becomes the one displayed and send out to the network, also, if you set this to an empty string but you specified your mode REQUIRES a parameter, this is equivalent to returning MODEACTION_DENY and will prevent the mode from being displayed. adding  This value is true when the mode is being set, or false when it is being unset. Returns: MODEACTION_ALLOW to allow the mode, or MODEACTION_DENY to prevent the mode, also see the description of 'parameter'. Reimplemented from ModeHandler.
