virtual | ~vrpn_LUDL_USBMAC6000 () |
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_BaseClass (const char *name, vrpn_Connection *c=NULL) | |
Names the device and assigns or opens connection, calls registration methods. | |
virtual | ~vrpn_BaseClass () |
virtual void | mainloop ()=0 |
Called once through each main loop iteration to handle updates. Remote object mainloop() should call client_mainloop() and then call d_connection->mainloop().

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. | |

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() | |
virtual int | register_types (void) |
