Member Function Documentation

void DeviceManagement::addLanDevice (  const std::string &  udi  )

add a lan device Parameters: udi  the device udi to add

void DeviceManagement::addSoundDevice (  const std::string &  udi  )

add a sound device Parameters: udi  the device udi to add

void DeviceManagement::addUsbDevice (  const std::string &  udi  )

add a usb device Parameters: udi  the device udi to add

void DeviceManagement::addWlanDevice (  const std::string &  udi  )

add a wlan device Parameters: udi  the device udi to add

bool DeviceManagement::checkDeviceAdded (  char *  udi  )

check if an added device can be added to out device list Parameters: udi  the device udi Returns: true if the the device was added

bool DeviceManagement::checkDeviceRemoved (  char *  udi  )

check if a removed device was one of our stored devices Parameters: udi  the device udi Returns: true if the device got remoced

int DeviceManagement::getDevices (  DPM_DEVICE_CLASS  device_class, std::list< std::string > &  udis, std::list< DPM_POWER_STATE > &  power_states )

get list of stored devices Parameters: device_class  get devices from this DPM_DEVICE_CLASS udis  stl list which get filled with udis power_states  stl list which get filled with power states Returns: number of devices

void DeviceManagement::init (   )

init all devices

bool DeviceManagement::resume (  DPM_DEVICE_CLASS  device_class, int  device_num = -1 )

resume devices Parameters: device_class  resume only devices from this class device_num  only resume device device_num (default is -1, means resume all of this class) Returns: false if no devices where resumed

bool DeviceManagement::suspend (  DPM_DEVICE_CLASS  device_class, int  device_num = -1, bool  force = false )

suspend devices Parameters: device_class  suspend only devices from this class device_num  only suspend device device_num (default is -1, means suspend all of this class) force  set to true if devices should be suspended although they are in use Returns: false if no devices where suspended

bool DeviceManagement::update (  std::list< DPM_DEVICE_CLASS >  rpm_classes, bool  force = false )

updates the powerstate of all devices function suspends those devices whos DPM_DEVICE_CLASS can be found in the given list rpm_classes. Devices not found are resumed Parameters: rpm_classes  list of DPM_DEVICE_CLASS which should get suspended force  set to true if devices should be suspended although they are in use Returns: false if no devices where suspended
