| __construct(Cli $input = null, Registry $config = null, DispatcherInterface $dispatcher = null) X-Ref |
| Class constructor. param: Cli $input An optional argument to provide dependency injection for the application's param: Registry $config An optional argument to provide dependency injection for the application's param: DispatcherInterface $dispatcher An optional argument to provide dependency injection for the application's |
| signal($signal) X-Ref |
| Method to handle POSIX signals. param: integer $signal The received POSIX signal. return: void |
| isActive() X-Ref |
| Check to see if the daemon is active. This does not assume that $this daemon is active, but only if an instance of the application is active as a daemon. return: boolean True if daemon is active. |
| loadConfiguration($data) X-Ref |
| Load an object or array into the application configuration object. param: mixed $data Either an array or object to be loaded into the configuration object. return: DaemonApplication Instance of $this to allow chaining. |
| execute() X-Ref |
| Execute the daemon. return: void |
| restart() X-Ref |
| Restart daemon process. return: void |
| stop() X-Ref |
| Stop daemon process. return: void |
| changeIdentity() X-Ref |
| Method to change the identity of the daemon process and resources. return: boolean True if identity successfully changed |
| daemonize() X-Ref |
| Method to put the application into the background. return: boolean |
| detach() X-Ref |
| This is truly where the magic happens. This is where we fork the process and kill the parent process, which is essentially what turns the application into a daemon. return: void |
| fork() X-Ref |
| Method to fork the process. return: integer The child process id to the parent process, zero to the child process. |
| gc() X-Ref |
| Method to perform basic garbage collection and memory management in the sense of clearing the stat cache. We will probably call this method pretty regularly in our main loop. return: void |
| setupSignalHandlers() X-Ref |
| Method to attach the DaemonApplication signal handler to the known signals. Applications can override these handlers by using the pcntl_signal() function and attaching a different callback method. return: boolean |
| shutdown($restart = false) X-Ref |
| Method to shut down the daemon and optionally restart it. param: boolean $restart True to restart the daemon on exit. return: void |
| writeProcessIdFile() X-Ref |
| Method to write the process id file out to disk. return: boolean |
| postFork() X-Ref |
| Method to handle post-fork triggering of the onFork event. return: void |
| pcntlChildExitStatus($status) X-Ref |
| Method to return the exit code of a terminated child process. param: integer $status The status parameter is the status parameter supplied to a successful call to pcntl_waitpid(). return: integer The child process exit code. |
| pcntlFork() X-Ref |
| Method to return the exit code of a terminated child process. return: integer On success, the PID of the child process is returned in the parent's thread |
| pcntlSignal($signal, $handler, $restart = true) X-Ref |
| Method to install a signal handler. param: integer $signal The signal number. param: callable $handler The signal handler which may be the name of a user created function, param: boolean $restart Specifies whether system call restarting should be used when this return: boolean True on success. |
| pcntlWait(&$status, $options = 0) X-Ref |
| Method to wait on or return the status of a forked child. param: integer &$status Status information. param: integer $options If wait3 is available on your system (mostly BSD-style systems), return: integer The process ID of the child which exited, -1 on error or zero if WNOHANG |
