Detailed Description

Prefix modes are channel modes that grant a specific rank to members having prefix mode set. They require a parameter when setting and unsetting; the parameter is always a member of the channel. A prefix mode may be set on any number of members on a channel, but for a given member a given prefix mode is either set or not set, in other words members cannot have the same prefix mode set more than once.

A rank of a member is defined as the rank given by the 'strongest' prefix mode that member has. Other parts of the IRCd use this rank to determine whether a channel action is allowable for a user or not. The rank of a prefix mode is constant, i.e. the same rank value is given to all users having that prefix mode set.

Note that it is possible that the same action requires a different rank on a different channel; for example changing the topic on a channel having +t set requires a rank that is >= than the rank of a halfop, but there is no such restriction when +t isn't set.

Constructor & Destructor Documentation

◆ PrefixMode()

PrefixMode::PrefixMode	(	Module *	Creator,
		const std::string &	Name,
		char	ModeLetter,
		unsigned int	Rank = `0`,
		char	PrefixChar = `0`
	)

Constructor

Parameters

Creator	The module creating this mode
Name	The user-friendly one word name of the prefix mode, e.g.: "op", "voice"
ModeLetter	The mode letter of this mode
Rank	Rank given by this prefix mode, see explanation above
PrefixChar	Prefix character, or 0 if the mode has no prefix character

Member Function Documentation

◆ AccessCheck()

ModResult PrefixMode::AccessCheck	(	User *	source,
		Channel *	channel,
		std::string &	parameter,
		bool	adding
	)

virtual

Called when a channel mode change access check for your mode occurs.

Parameters

source	Contains the user setting the mode.
channel	contains the destination channel the modes are being set on.
parameter	The parameter for your mode. This is modifiable.
adding	This value is true when the mode is being set, or false when it is being unset.

Returns: allow, deny, or passthru to check against the required level

Reimplemented from ModeHandler.

◆ CanSelfRemove()

bool PrefixMode::CanSelfRemove ( ) const

inline

Determines whether a user with this prefix mode can remove it.

◆ GetPrefix()

char PrefixMode::GetPrefix ( ) const

inline

Mode prefix or 0. If this is defined, you should also implement GetPrefixRank() to return an integer value for this mode prefix.

◆ GetPrefixRank()

unsigned int PrefixMode::GetPrefixRank ( ) const

inline

Get the 'value' of this modes prefix. determines which to display when there are multiple. The mode with the highest value is ranked first. See the PrefixModeValue enum and Channel::GetPrefixValue() for more information.

◆ OnModeChange()

ModeAction PrefixMode::OnModeChange	(	User *	source,
		User *	dest,
		Channel *	channel,
		std::string &	param,
		bool	adding
	)

virtual

Handles setting and unsetting the prefix mode. Finds the given member of the given channel, if it's not found an error message is sent to 'source' and MODEACTION_DENY is returned. Otherwise the mode change is attempted.

Parameters

source	Source of the mode change, an error message is sent to this user if the target is not found
dest	Unused
channel	The channel the mode change is happening on
param	The nickname or uuid of the target user
adding	True when the mode is being set, false when it is being unset

Returns: MODEACTION_ALLOW if the change happened, MODEACTION_DENY if no change happened The latter occurs either when the member cannot be found or when the member already has this prefix set (when setting) or doesn't have this prefix set (when unsetting).

Reimplemented from ModeHandler.

◆ RemoveMode()

void PrefixMode::RemoveMode	(	Channel *	channel,
		Modes::ChangeList &	changelist
	)

virtual

Removes this prefix mode from all users on the given channel

Parameters

channel	The channel which the server wants to remove your mode from
changelist	Mode change list to populate with the removal of this mode

Reimplemented from ModeHandler.

◆ Update()

void PrefixMode::Update	(	unsigned int	rank,
		unsigned int	setrank,
		unsigned int	unsetrank,
		bool	selfrm
	)

Updates the configuration of this prefix.

Parameters

rank	The prefix rank of this mode.
setrank	The prefix rank required to set this mode on channels.
unsetrank	The prefix rank required to set this unmode on channels.
selfrm	Whether a client with this prefix can remove it from themself.

Member Data Documentation

◆ prefix

char PrefixMode::prefix

protected

The prefix character granted by this mode. '@' for op, '+' for voice, etc. If 0, this mode does not have a visible prefix character.

◆ prefixrank

unsigned int PrefixMode::prefixrank

protected

The prefix rank of this mode, used to compare prefix modes

◆ selfremove

bool PrefixMode::selfremove

protected

Whether a client with this prefix can remove it from themself.
