JApplicationDaemon::__construct	(	JInputCli	$input = `null`,
		JRegistry	$config = `null`,
		JDispatcher	$dispatcher = `null`
	)

Class constructor.

Paramètres:

mixed	$input	An optional argument to provide dependency injection for the application's input object. If the argument is a JInputCli object that object will become the application's input object, otherwise a default input object is created.
mixed	$config	An optional argument to provide dependency injection for the application's config object. If the argument is a JRegistry object that object will become the application's config object, otherwise a default config object is created.
mixed	$dispatcher	An optional argument to provide dependency injection for the application's event dispatcher. If the argument is a JDispatcher object that object will become the application's event dispatcher, if it is null then the default event dispatcher will be created based on the application's loadDispatcher() method.

Depuis:: 11.1

Exceptions:

RuntimeException

JApplicationDaemon::changeIdentity ( )

protected

Method to change the identity of the daemon process and resources.

Renvoie:: boolean True if identity successfully changed

Depuis:: 11.1

Voir également:: posix_setuid()

Références $file, $user, JLog\add(), JLog\ERROR, et JLog\INFO.

Voici le graphe d'appel pour cette fonction :

JApplicationDaemon::daemonize ( )

protected

Method to put the application into the background.

Renvoie:: boolean

Depuis:: 11.1

Exceptions:

RuntimeException

Références JLog\add(), JLog\CRITICAL, JLog\EMERGENCY, et JLog\WARNING.

Voici le graphe d'appel pour cette fonction :

JApplicationDaemon::detach ( )

protected

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.

Renvoie:: void

Depuis:: 12.1

Exceptions:

RuntimeException

Références JLog\add(), et JLog\DEBUG.

Voici le graphe d'appel pour cette fonction :

JApplicationDaemon::fork ( )

protected

Method to fork the process.

Renvoie:: integer The child process id to the parent process, zero to the child process.

Depuis:: 11.1

Exceptions:

RuntimeException

Références JLog\add(), JLog\DEBUG, et elseif.

Voici le graphe d'appel pour cette fonction :

JApplicationDaemon::gc ( )

protected

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.

Renvoie:: void

Depuis:: 11.1

JApplicationDaemon::isActive ( )

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.

Renvoie:: boolean True if daemon is active.

Depuis:: 11.1

Références JLog\add(), et JLog\WARNING.

Voici le graphe d'appel pour cette fonction :

JApplicationDaemon::loadConfiguration ( $data )

Load an object or array into the application configuration object.

Paramètres:

mixed $data Either an array or object to be loaded into the configuration object.

Renvoie:: JCli Instance of $this to allow chaining.

Depuis:: 11.1

Réimplémentée à partir de JApplicationCli.

Références $data, $name, $options, et null.

JApplicationDaemon::pcntlChildExitStatus ( $status )

protected

Method to return the exit code of a terminated child process.

Paramètres:

integer $status The status parameter is the status parameter supplied to a successful call to pcntl_waitpid().

Renvoie:: integer The child process exit code.

Voir également:: pcntl_wexitstatus()

Depuis:: 11.3

JApplicationDaemon::pcntlFork ( )

protected

Method to return the exit code of a terminated child process.

Renvoie:: integer On success, the PID of the child process is returned in the parent's thread of execution, and a 0 is returned in the child's thread of execution. On failure, a -1 will be returned in the parent's context, no child process will be created, and a PHP error is raised.

Depuis:: 11.3

JApplicationDaemon::pcntlSignal	(	$signal,
		$handler,
		$restart = `true`
	)

protected

Method to install a signal handler.

Paramètres:

integer	$signal	The signal number.
callback	$handler	The signal handler which may be the name of a user created function, or method, or either of the two global constants SIG_IGN or SIG_DFL.
boolean	$restart	Specifies whether system call restarting should be used when this signal arrives.

Renvoie:: boolean True on success.

Voir également:: pcntl_signal()

Depuis:: 11.3

JApplicationDaemon::pcntlWait	(	&	$status,
			$options = `0`
	)

protected

Method to wait on or return the status of a forked child.

Paramètres:

integer	&$status	Status information.
integer	$options	If wait3 is available on your system (mostly BSD-style systems), you can provide the optional options parameter.

Renvoie:: integer The process ID of the child which exited, -1 on error or zero if WNOHANG was provided as an option (on wait3-available systems) and no child was available.

Depuis:: 11.3

Références $options.

JApplicationDaemon::postFork ( )

protected

Method to handle post-fork triggering of the onFork event.

Renvoie:: void

Depuis:: 12.1

JApplicationDaemon::restart ( )

Restart daemon process.

Renvoie:: void

Depuis:: 11.1

JApplicationDaemon::setupSignalHandlers ( )

protected

Method to attach the JApplicationDaemon signal handler to the known signals. Applications can override these handlers by using the pcntl_signal() function and attaching a different callback method.
