Public Member Functions

void SetCustomMode (char mode, bool mode_on)
 Sets or unsets a custom mode in the channels info.

void SetCustomModeParam (char mode, char *parameter, bool mode_on)
 Sets or unsets the parameters for a custom mode in a channels info.

bool IsCustomModeSet (char mode)
 Returns true if a custom mode is set on a channel.

std::string GetModeParameter (char mode)
 Returns the parameter for a custom mode on a channel.

long GetUserCounter ()
 Obtain the channel "user counter" This returns the channel reference counter, which is initialized to 0 when the channel is created and incremented/decremented upon joins, parts quits and kicks.

void AddUser (char *castuser)
 Add a user pointer to the internal reference list The data inserted into the reference list is a table as it is an arbitary pointer compared to other users by its memory address, as this is a very fast 32 or 64 bit integer comparison.

void DelUser (char *castuser)
 Delete a user pointer to the internal reference list The data removed from the reference list is a table as it is an arbitary pointer compared to other users by its memory address, as this is a very fast 32 or 64 bit integer comparison.

std::vector< char * > * GetUsers ()
 Obrain the internal reference list The internal reference list contains a list of userrec* cast to char*.

 chanrec ()
 Creates a channel record and initialises it with default values.

virtual ~chanrec ()

 Creation time.

time_t topicset
 Time topic was set.

char setby [NICKMAX]
 The last user to set the topic.

Add a user pointer to the internal reference list The data inserted into the reference list is a table as it is an arbitary pointer compared to other users by its memory address, as this is a very fast 32 or 64 bit integer comparison.

void chanrec::DelUser char *  castuser  ) 
 

Delete a user pointer to the internal reference list The data removed from the reference list is a table as it is an arbitary pointer compared to other users by its memory address, as this is a very fast 32 or 64 bit integer comparison.

00225 }

std::string chanrec::GetModeParameter char  mode  ) 
 

Returns the parameter for a custom mode on a channel.

For example if "+L #foo" is set, and you pass this method 'L', it will return '#foo'. If the mode is not set on the channel, or the mode has no parameters associated with it, it will return an empty string.

std::vector< char * > * chanrec::GetUsers  ) 
 

Obrain the internal reference list The internal reference list contains a list of userrec* cast to char*.

These are used for rapid comparison to determine channel membership for PRIVMSG, NOTICE, QUIT, PART etc. The resulting pointer to the vector should be considered readonly and only modified via AddUser and DelUser.
