Member Function Documentation

void chanrec::AddUser (  char *  castuser  ) 
 

Add a user pointer to the internal reference list.

Parameters:
castuser This should be a pointer to a userrec, casted to char*
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.

Definition at line 166 of file channels.cpp.

References DEBUG, and internal_userlist.

00167 {
00168         internal_userlist.push_back(castuser);
00169         log(DEBUG,"Added casted user to channel's internal list");
00170 }

void chanrec::DelUser (  char *  castuser  ) 
 

Delete a user pointer to the internal reference list.

Parameters:
castuser This should be a pointer to a userrec, casted to char*
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.

00183         log(DEBUG,"BUG BUG BUG! Attempt to remove an uncasted user from the internal list of %s!",name);
00184 }

std::string chanrec::GetModeParameter (  char  mode  ) 
 

Returns the parameter for a custom mode on a channel.

Parameters:
mode The mode character you wish to query
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.

Returns:
The parameter for this mode is returned, or an empty string

long chanrec::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.

Returns:
The number of users on this channel

00163         return (this->internal_userlist.size());
00164 }

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.

Returns:
This function returns a vector of userrec pointers, each of which has been casted to char* to prevent circular references

bool chanrec::IsCustomModeSet (  char  mode  ) 
 

Returns true if a custom mode is set on a channel.

Parameters:
mode The mode character you wish to query
Returns:
True if the custom mode is set, false if otherwise

void chanrec::SetCustomMode (  char  mode,
bool  mode_on
) 
 

Sets or unsets a custom mode in the channels info.

Parameters:
