Member Function Documentation

virtual void NLMISC::IInputDevice::begin (  CEventServer *  server  )  [inline, virtual]

For device server usage : Called at the beginning of each events retrieval. If a device doesn't support buffered datas, the state changes can be directly send to the event server. The default does nothing. Definition at line 64 of file input_device.h. {}

virtual uint NLMISC::IInputDevice::getBufferSize (   )  const [pure virtual]

Get the buffer size for this device.

virtual void NLMISC::IInputDevice::poll (  CInputDeviceServer *  dev  )  [pure virtual]

For device server usage : Poll all events from that device, and notify them to the given device server, so that they can be sorted between devices. This retrieves messages, but do not process them.

virtual bool NLMISC::IInputDevice::setBufferSize (  uint  size  )  [pure virtual]

Set the buffer size for this device (the number of samples it can retains). This return true if the size could be set

virtual void NLMISC::IInputDevice::submit (  IInputDeviceEvent *  deviceEvent, CEventServer *  server )  [pure virtual]

For device server usage : Process an event (eventually update this device state), and translate the message to a IEventServerMessage

virtual void NLMISC::IInputDevice::transitionOccured (  CEventServer *  server, const IInputDeviceEvent *  nextMessage )  [inline, virtual]

For device server usage : Says that the next message is for another device, or that it is the last message that will be received. This allow to pack several messages in one (for example, to sum up mouse moves until a click occurs) The default does nothing. The next message can be used to get a time stamp for example. It may be NULL is no next message is available Definition at line 81 of file input_device.h. Referenced by NLMISC::CInputDeviceServer::poll(). {}
