Public Member Functions

 vrpn_Analog_Output_Server (const char *name, vrpn_Connection *c, vrpn_int32 numChannels=vrpn_CHANNEL_MAX)
 
virtual ~vrpn_Analog_Output_Server (void)
 
virtual void mainloop ()
 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().
 
vrpn_int32 setNumChannels (vrpn_int32 sizeRequested)
 Sets the size of the array; returns the size actually set. (May be clamped to vrpn_CHANNEL_MAX) This should be used before mainloop is ever called.
 
const vrpn_float64 * o_channels (void) const
 Exposes an array of values for the user to read from.
 
- Public Member Functions inherited from vrpn_Analog_Output
 vrpn_Analog_Output (const char *name, vrpn_Connection *c=NULL)
 
void o_print (void)
 
vrpn_int32 getNumChannels () const
 
- Public Member Functions inherited from vrpn_BaseClass
 vrpn_BaseClass (const char *name, vrpn_Connection *c=NULL)
 Names the device and assigns or opens connection, calls registration methods.
 
virtual ~vrpn_BaseClass ()
 
- Public Member Functions inherited from vrpn_BaseClassUnique
 vrpn_BaseClassUnique ()
 
virtual ~vrpn_BaseClassUnique ()
 Unregister all of the message handlers that were to be autodeleted.
 
vrpn_ConnectionconnectionPtr ()
 Returns a pointer to the connection this object is using.
 

Protected Member Functions

virtual vrpn_int32 encode_num_channels_to (char *buf, vrpn_int32 num)
 
- Protected Member Functions inherited from vrpn_Analog_Output
virtual int register_types (void)
 Register the types of messages this device sends/receives. Return 0 on success, -1 on fail.
 
- Protected Member Functions inherited from vrpn_BaseClass
virtual int init (void)
 Initialize things that the constructor can't. Returns 0 on success, -1 on failure.
 
virtual int register_senders (void)
 Register the sender for this device (by default, the name of the device). Return 0 on success, -1 on fail.
 
- Protected Member Functions inherited from vrpn_BaseClassUnique
int register_autodeleted_handler (vrpn_int32 type, vrpn_MESSAGEHANDLER handler, void *userdata, vrpn_int32 sender=vrpn_ANY_SENDER)
 Registers a handler with the connection, and remembers to delete at destruction.
 
int send_text_message (const char *msg, struct timeval timestamp, vrpn_TEXT_SEVERITY type=vrpn_TEXT_NORMAL, vrpn_uint32 level=0)
 Sends a NULL-terminated text message from the device d_sender_id.
 
SendTextMessageBoundCall send_text_message (vrpn_TEXT_SEVERITY type=vrpn_TEXT_NORMAL)
 Returns an object you can stream into to send a text message from the device like send_text_message(vrpn_TEXT_WARNING) << "Value of i is: " << i; This use requires including vrpn_SendTextMessageStreamProxy.h.
 
void server_mainloop (void)
 Handles functions that all servers should provide in their mainloop() (ping/pong, for example) Should be called by all servers in their mainloop()
 
void client_mainloop (void)
 Handles functions that all clients should provide in their mainloop() (warning of no server, for example) Should be called by all clients in their mainloop()
 

Static Protected Member Functions

static int VRPN_CALLBACK handle_request_message (void *userdata, vrpn_HANDLERPARAM p)
 Responds to a request to change one of the values by setting the channel to that value. Derived class must either install handlers for this routine or else make its own routines to handle the request message.
 
static int VRPN_CALLBACK handle_request_channels_message (void *userdata, vrpn_HANDLERPARAM p)
 Responds to a request to change a number of channels Derived class must either install handlers for this routine or else make its own routines to handle the multi-channel request message.
 
static int VRPN_CALLBACK handle_got_connection (void *userdata, vrpn_HANDLERPARAM p)
 Used to notify us when a new connection is requested, so that we can let the client know how many channels are active.
 
- Static Protected Member Functions inherited from vrpn_BaseClassUnique
static int encode_text_message_to_buffer (char *buf, vrpn_TEXT_SEVERITY severity, vrpn_uint32 level, const char *msg)
 Encodes the body of the text message into a buffer, preparing for sending.
 
static int decode_text_message_from_buffer (char *msg, vrpn_TEXT_SEVERITY *severity, vrpn_uint32 *level, const char *buf)
 Decodes the body of the text message from a buffer from the connection.
