Public Member Functions

 vrpn_Vality_vGlass (const char *name, vrpn_Connection *c=0)
 
virtual ~vrpn_Vality_vGlass (void)
 
virtual void mainloop (void)
 Called once through each main loop iteration to handle updates. Remote object mainloop() should call client_mainloop() and then call d_connection->mainloop(). Server object mainloop() should service the device and then call server_mainloop(), but should not normally call d_connection->mainloop().

 Constructor If we already have a HID device from some other source, it can be passed and we'll take ownership: still need the acceptor for reconnect, we just won't do it right away.
 
 vrpn_HidInterface (vrpn_HidAcceptor *acceptor, hid_device *device)
 Simplified constructor that just takes an acceptor and an underlying HID device (both non-optional).
 
 vrpn_HidInterface (const char *device_path, vrpn_HidAcceptor *acceptor, vrpn_uint16 vendor=0, vrpn_uint16 product=0)
 Constructor If we already know the path to the device we want, we can pass it in and open it directly: still need the acceptor for reconnect enumeration, we just won't do it right away.
 
virtual ~vrpn_HidInterface ()
 
virtual bool connected () const
 Returns true iff the last device I/O succeeded.
 
virtual void update ()
 Polls the device buffers and causes on_data_received callbacks if appropriate You NEED to call this frequently to ensure the OS doesn't drop data.
 
virtual bool reconnect ()
 Tries to reconnect to an acceptable device. Call this if you suspect a hotplug event has occurred.
 
vrpn_uint16 vendor () const
 Returns USB vendor ID of connected device May not contain valid if an already-open device was provided to the constructor.
