Constructor & Destructor Documentation

MNSelector::MNSelector (  bool  notifiable  )

Each selector may implement an internal pipe that allows it to be waken up for an arbitrary reason. Such reasons may be the insertion of a new socket, a clean deletion of a class that has a socket registered at this selector, or somesuch. The external notifier classes make sense in specialized cases, but if the selector is shared by many sockets, it is cheaper to integrated the pipe. Parameters: notifiable  Pass true if the selector should have a notifier pipe. The pipe can only be created at instantiation time.

Member Function Documentation

void MNSelector::cancel_all_timers (   )

bool MNSelector::cancel_timer (  TimerCallBase *  timerptr  )

void MNSelector::insert (  MNSocketBase *  socketptr, bool  threaded, const char *  caller, u_int32_t  set = MNSelector::READSET )

Use this function to insert a new file descriptor struct into the selector for observation. Some of the socket classes include this call in their constructor, for others it must be called manually. Look there. Parameters: socketptr  A pointer to the class that encapsulated the new file descriptor or socket to observe. threaded  Nothing if false. If true, the wakeup member function is called, which signals on the internal notification pipe and to end the select system call. This works only if the selector is notifiable, and results in an MN_FATAL if it is not. caller  A string that identifies the entity that inserts this socket into the selector. This is meant for debugging only.

bool MNSelector::insert_abs_timer (  void *  data, TimerCallBase *  timerptr, const struct timeval &  timeout, const char *  owner )

bool MNSelector::insert_periodic_timer (  void *  data, TimerCallBase *  timerptr, const struct timeval &  timeout, const char *  owner )

bool MNSelector::insert_rel_timer (  void *  data, TimerCallBase *  timerptr, const struct timeval &  timeout, const char *  owner )

bool MNSelector::notifiable (   )  const

void MNSelector::remove_fd (  MNSocketBase *  socketptr  )

void MNSelector::remove_fd (  int  fd, u_int32_t  set = MNSelector::BOTHSETS )

void MNSelector::select (   )

void MNSelector::wakeup (   )

Send a byte to the notification pipe and wake the selector up for some arbitrary processing. If the selector has been created with this capability, this results in an assertion.
