Public Member Functions | |
vrpn_ImagerPose_Remote (const char *name, vrpn_Connection *c=NULL) | |
virtual int | register_description_handler (void *userdata, vrpn_IMAGERDESCRIPTIONHANDLER handler) |
Register a handler for when the object's description changes (if desired) | |
virtual int | unregister_description_handler (void *userdata, vrpn_IMAGERDESCRIPTIONHANDLER handler) |
virtual void | mainloop (void) |
Call this each time through the program's main loop. | |
![]() | |
vrpn_ImagerPose (const char *name, vrpn_Connection *c=NULL) | |
void | get_origin (vrpn_float64 *origin) const |
Returns the origin of the coordinate system,. | |
void | get_dCol (vrpn_float64 *dCol) const |
This is the total span of the image in columns;. | |
void | get_dRow (vrpn_float64 *dRow) const |
This is the total span of the image in rows;. | |
void | get_dDepth (vrpn_float64 *dDepth) const |
This is the total span of the image in depth;. | |
bool | compute_pixel_center (vrpn_float64 *center, const vrpn_Imager &image, vrpn_uint16 col, vrpn_uint16 row, vrpn_uint16 depth=0) |
This will return the location of the center of the specified. | |
![]() | |
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(). Server object mainloop() should service the device and then call server_mainloop(), but should not normally call d_connection->mainloop(). | |
![]() | |
vrpn_BaseClassUnique () | |
virtual | ~vrpn_BaseClassUnique () |
Unregister all of the message handlers that were to be autodeleted. | |
vrpn_Connection * | connectionPtr () |
Returns a pointer to the connection this object is using. | |
Static Protected Member Functions | |
static int VRPN_CALLBACK | handle_description_message (void *userdata, vrpn_HANDLERPARAM p) |
Handler for resolution and channel list message from the server. | |
![]() | |
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. | |

Connection that this object talks to. | |
char * | d_servicename |
Name of this device, not including the connection part. | |
vrpn_int32 | d_sender_id |
Sender ID registered with the connection. | |
vrpn_int32 | d_text_message_id |
ID for text messages. | |
vrpn_int32 | d_ping_message_id |
Ask the server if they are there. | |
vrpn_int32 | d_pong_message_id |
Server telling that it is there. | |
Additional Inherited Members | |
![]() | |
bool | shutup |
![]() | |
virtual int | register_types (void) |
Register the types of messages this device sends/receives. Return 0 on success, -1 on fail. | |
![]() | |
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. | |
virtual int | register_types (void)=0 |
Register the types of messages this device sends/receives. Return 0 on success, -1 on fail. | |
![]() | |
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() | |
