Also, plugins can switch the cKbdRemote class into "raw mode", where all keyboard input will be made available through the new 'kKbd' key code and none of it will be processed as normal remote control functions (thanks to Jan Rieger for suggestions and testing). - Fixed deleting characters in string entry fields in 'insert' mode. - Now using "Doxygen" to generate source documentation (thanks to Walter Stroebel for providing an initial 'Doxyfile' configuration and adjusting some comments). See INSTALL for information how to do this. Some function descriptions have already been adapted to Doxygen, more will follow. --- device.h | 366 +++++++++++++++++++++++++++++++++------------------------------ 1 file changed, 191 insertions(+), 175 deletions(-) (limited to 'device.h') diff --git a/device.h b/device.h index cc2be79..f18699c 100644 --- a/device.h +++ b/device.h @@ -4,7 +4,7 @@ * See the main source file 'vdr.c' for copyright information and * how to reach the author. * - * $Id: device.h 1.27 2002/11/03 11:16:11 kls Exp $ + * $Id: device.h 1.28 2002/12/15 14:40:11 kls Exp $ */ #ifndef __DEVICE_H @@ -50,6 +50,8 @@ class cPlayer; class cReceiver; class cSpuDecoder; +/// The cDevice class is the base from which actual devices can be derived. + class cDevice : public cThread { private: static int numDevices; @@ -58,32 +60,35 @@ private: static cDevice *primaryDevice; public: static int NumDevices(void) { return numDevices; } - // Returns the total number of devices. + ///< Returns the total number of devices. static void SetUseDevice(int n); - // Sets the 'useDevice' flag of the given device. - // If this function is not called before initializing, all devices - // will be used. + ///< Sets the 'useDevice' flag of the given device. + ///< If this function is not called before initializing, all devices + ///< will be used. static bool UseDevice(int n) { return useDevice == 0 || (useDevice & (1 << n)) != 0; } - // Tells whether the device with the given card index shall be used in - // this instance of VDR. + ///< Tells whether the device with the given card index shall be used in + ///< this instance of VDR. static bool SetPrimaryDevice(int n); - // Sets the primary device to 'n' (which must be in the range - // 1...numDevices) and returns true if this was possible. + ///< Sets the primary device to 'n'. + ///< \param n must be in the range 1...numDevices. + ///< \return true if this was possible. static cDevice *PrimaryDevice(void) { return primaryDevice; } - // Returns the primary device. + ///< Returns the primary device. static cDevice *GetDevice(int Index); - // Returns the device with the Index (if Index is in the range - // 0..numDevices-1, NULL otherwise). + ///< Gets the device with the given Index. + ///< \param Index must be in the range 0..numDevices-1. + ///< \return A pointer to the device, or NULL if the Index was invalid. static cDevice *GetDevice(const cChannel *Channel, int Priority = -1, bool *NeedsDetachReceivers = NULL); - // Returns a device that is able to receive the given Channel at the - // given Priority (see ProvidesChannel() for more information on how - // priorities are handled, and the meaning of NeedsDetachReceivers). + ///< Returns a device that is able to receive the given Channel at the + ///< given Priority. + ///< See ProvidesChannel() for more information on how + ///< priorities are handled, and the meaning of NeedsDetachReceivers. static void SetCaCaps(int Index = -1); - // Sets the CaCaps of the given device according to the Setup data. - // By default the CaCaps of all devices are set. + ///< Sets the CaCaps of the given device according to the Setup data. + ///< By default the CaCaps of all devices are set. static void Shutdown(void); - // Closes down all devices. - // Must be called at the end of the program. + ///< Closes down all devices. + ///< Must be called at the end of the program. private: static int nextCardIndex; int cardIndex; @@ -92,49 +97,50 @@ protected: cDevice(void); virtual ~cDevice(); static int NextCardIndex(int n = 0); - // Each device in a given machine must have a unique card index, which - // will be used to identify the device for assigning Ca parameters and - // deciding whether to actually use that device in this particular - // instance of VDR.
