Detailed Description

A radio frequency channel hopper.

This class provides a channel hopper for radio frequencies. A channel hopper frequently changes the radio frequency channel of its associated OWirelessNetworkInterface. This is necessary when in monitoring mode and scanning for other devices, because the radio frequency hardware can only detect packets sent on the same frequency.

Member Function Documentation

int Opie::Net::OChannelHopper::channel (   )  const

Returns: the last hopped channel Definition at line 415 of file onetwork.cpp. References _channel. Referenced by Opie::Net::OWirelessNetworkInterface::channel().

void Opie::Net::OChannelHopper::hopped (  int   )  [signal]

This signal is emitted right after the channel hopper performed a hop Referenced by timerEvent().

int Opie::Net::OChannelHopper::interval (   )  const

Returns: the channel hopping interval Definition at line 448 of file onetwork.cpp. References _interval. Referenced by Opie::Net::OWirelessNetworkInterface::channelHopping().

bool Opie::Net::OChannelHopper::isActive (   )  const

Returns: true, if the channel hopper is hopping channels Definition at line 409 of file onetwork.cpp. References _tid. Referenced by Opie::Net::OWirelessNetworkInterface::channel().

void Opie::Net::OChannelHopper::setInterval (  int  interval  )

Set the channel hopping interval. An interval of 0 deactivates the channel hopper. Definition at line 430 of file onetwork.cpp. References _interval, and _tid. Referenced by Opie::Net::OWirelessNetworkInterface::setChannelHopping().

void Opie::Net::OChannelHopper::timerEvent (  QTimerEvent *   )  [protected, virtual]

Definition at line 421 of file onetwork.cpp. References _channel, _channels, _iface, QValueList< T >::begin(), QValueList< T >::end(), hopped(), odebug, oendl, and Opie::Net::OWirelessNetworkInterface::setChannel().
