Member Function Documentation

void PStatServer::add_reader (  Connection *  connection, PStatReader *  reader )  [inherited]

Adds the newly-created PStatReader to the list of currently active readers. Definition at line 202 of file pStatServer.cxx. References PStatServer::_available_udp_ports. Referenced by PStatListener::PStatListener().

int PStatServer::get_udp_port (   )  [inherited]

Returns a new port number that will probably be free to use as a UDP port. The caller should be prepared to accept the possibility that it will be already in use by another process, however. Definition at line 241 of file pStatServer.cxx. References PStatServer::_lost_readers, PStatServer::_readers, and reader(). Referenced by PStatReader::close().

bool PStatServer::is_thread_safe (   )  [virtual, inherited]

This should be redefined to return true in derived classes that want to deal with multithreaded readers and such. If this returns true, the manager will create the listener in its own thread, and thus the PStatReader constructors at least will run in a different thread. This is not related to the question of whether the reader can handle multiple different PStatThreadDatas; it's strictly a question of whether the readers themselves can run in a separate thread. Definition at line 294 of file pStatServer.cxx.

bool PStatServer::listen (  int  port = -1  )  [inherited]

Establishes a port number that the manager will listen on for TCP connections. This may be called more than once to listen simulataneously on multiple connections, as if that were at all useful. The default parameter, -1, indicates the use of whatever port number has been indicated in the Config file. This function returns true if the port was successfully opened, or false if it could not open the port. Definition at line 84 of file pStatServer.cxx. References PStatServer::_listener, PStatServer::_lost_readers, PStatServer::_readers, PStatServer::_removed_readers, ConnectionListener::poll(), and reader(). Referenced by TextStats::make_monitor().

void PStatServer::main_loop (  bool *  interrupt_flag = NULL  )  [inherited]

An alternative to repeatedly calling poll(), this function yields control of the program to the PStatServer. It does not return until the program is done. If interrupt_flag is non-NULL, it is the address of a bool variable that is initially false, and may be asynchronously set true to indicate the loop should terminate. Definition at line 181 of file pStatServer.cxx. References PStatServer::_available_udp_ports, and PStatServer::_next_udp_port.

PStatMonitor * GtkStatsServer::make_monitor (   )  [virtual]

Implements PStatServer. Definition at line 34 of file gtkStatsServer.cxx.

void PStatServer::poll (   )  [inherited]

Checks for any network activity and handles it, if appropriate, and then returns. This must be called periodically unless is_thread_safe() is redefined to return true on this class and also on all PStatMonitors in use. Alternatively, a program may call main_loop() and yield control of the program entirely to the PStatServer. Definition at line 132 of file pStatServer.cxx. References NULL.

void PStatServer::release_udp_port (  int  port  )  [inherited]

Indicates that the given UDP port is once again free for use. Definition at line 261 of file pStatServer.cxx.

void PStatServer::remove_reader (  Connection *  connection, PStatReader *  reader )  [inherited]

Removes the indicated reader. Definition at line 215 of file pStatServer.cxx. Referenced by PStatReader::~PStatReader().
