Detailed Description

class implementing a main loop with glib

Cares about callbacks and executes appropriate functions from PM_Interface

Constructor & Destructor Documentation

MainLoop::MainLoop (   )

constructor initializing the MainLoop object Constructor setting up the dbus connection and the gmain loop. For running the main loop, you have to call run().

Member Function Documentation

int MainLoop::addCallback (  int  interval, gboolean(*)(gpointer data)  function )

adds a callback to the main loop adds a callback function with the given interval to the gmain loop Parameters: interval  interval on which the function should be called function  the function pointer serving as callback

gboolean MainLoop::adjustSpeeds_callback (  gpointer  data  )  [static, private]

callback for adjust cpu speed in case of cpufreq userspace calls CPUFreq::adjustSpeeds If cpu, function returns false is not called again Parameters: data  user data Returns: true on success, false otherwise. If false, the callback is never called again.

gboolean MainLoop::checkEventTimeouts_callback (  gpointer  data  )  [static, private]

callback for checking pending powersave events calls pm->checkEventTimeouts(); Parameters: data  user data Returns: true on success, false otherwise. If false, the callback is never called again.

gboolean MainLoop::checkThrottling_callback (  gpointer  data  )  [static, private]

callback for updating the cpu state inside PM_interface calls pm->updateCPUState(); Returns: true on success, false otherwise. If false, the callback is never called again.

gboolean MainLoop::hwEvent_callback (  GIOChannel *  io_channel, GIOCondition  io_condition, gpointer  data )  [static, private]

callback for events on acpi/apm event file Function is called whenever there is an event on the hw event filedescriptor. Defined static to be used as gmain loop callback Parameters: io_channel  the io channel used by glib io_condition  conditions on what we listen data  user data Returns: true on success, false otherwise. If false, the callback is not called again until readded

gboolean MainLoop::hwEvent_connect (   )  [static, private]

connects to the hw event file (apm/acpi) Function is called successively when hw event channel broke away. Defined static to be used inside static callback functions. Returns: true on success, false otherwise.

gboolean MainLoop::hwEvent_reconnect (  gpointer  data  )  [static, private]

callback for reconnection to the hwEvent channel Function is called successively when hw event channel broke away until it is back again.. Defined static to be used as gmain loop callback Parameters: data  user data Returns: true on success, false otherwise. If false, the callback is never called again

void MainLoop::quit (   )

quits the main loop

void MainLoop::run (   )

runs the main loop Runs the main loop and blocks until quit() is called.

void MainLoop::setupCallbacks (   )  [private]

adds callbacks to the main loop Adds the default callbacks to the main loop.

void MainLoop::updateCallbacks (   )

updates all callbacks within the main loop Updates all callbacks within the main loop. If a callback already exists, do nothing. This function should be called whenever there is a config/scheme/hardware change. It needs less ressources, so it is no problem to call it as often as needed.
