Public Member Functions

virtual ~vrpn_Connection (void)
 
virtual vrpn_bool doing_okay (void) const
 Returns vrpn_true if the connection is okay, vrpn_false if not.
 
virtual vrpn_bool connected (void) const
 Returns vrpn_true if the connection has been established, vrpn_false if not (For a networkless connection, this is equivalent to doing_okay()).
 
void get_log_names (char **local_in_logname, char **local_out_logname, char **remote_in_logname, char **remote_out_logname)
 This function returns the logfile names of this connection in the parameters. It will allocate memory for the name of each log file in use. If no logging of a particular type is happening, then *(X_Y_logname) will be set to NULL. IMPORTANT: code calling this function is responsible for freeing the memory allocated for these strings.
 
virtual int mainloop (const struct timeval *timeout=NULL)=0
 Call each time through program main loop to handle receiving any incoming messages and sending any packed messages. Returns -1 when connection dropped due to error, 0 otherwise. (only returns -1 once per connection drop). Optional argument is TOTAL time to block on select() calls; there may be multiple calls to select() per call to mainloop(), and this timeout will be divided evenly between them.
 
virtual vrpn_int32 register_sender (const char *name)
 Get a token to use for the string name of the sender or type. Remember to check for -1 meaning failure.
 
virtual vrpn_int32 register_message_type (const char *name)
 
virtual int register_handler (vrpn_int32 type, vrpn_MESSAGEHANDLER handler, void *userdata, vrpn_int32 sender=vrpn_ANY_SENDER)
 Set up (or remove) a handler for a message of a given type. Optionally, specify which sender to handle messages from. Handlers will be called during mainloop(). Your handler should return 0 or a communication error is assumed and the connection will be shut down.
 
virtual int unregister_handler (vrpn_int32 type, vrpn_MESSAGEHANDLER handler, void *userdata, vrpn_int32 sender=vrpn_ANY_SENDER)
 
virtual int pack_message (vrpn_uint32 len, struct timeval time, vrpn_int32 type, vrpn_int32 sender, const char *buffer, vrpn_uint32 class_of_service)
 Pack a message that will be sent the next time mainloop() is called. Turn off the RELIABLE flag if you want low-latency (UDP) send.
 
virtual int send_pending_reports (void)=0
 send pending report, clear the buffer. This function was protected, now is public, so we can use it to send out intermediate results without calling mainloop
 
virtual int time_since_connection_open (struct timeval *elapsed_time)
 Returns the time since the connection opened. Some subclasses may redefine time.
 
virtual timeval get_time ()
 returns the current time in the connection (since the epoch – UTC time).
 
virtual const char * sender_name (vrpn_int32 sender)
 Returns the name of the specified sender/type, or NULL if the parameter is invalid. Only works for user messages (type >= 0).
 
virtual const char * message_type_name (vrpn_int32 type)
 
virtual int register_log_filter (vrpn_LOGFILTER filter, void *userdata)
 Sets up a filter function for logging. Any user message to be logged is first passed to this function, and will only be logged if the function returns zero (XXX). NOTE: this only affects local logging - remote logging is unfiltered! Only user messages are filtered; all system messages are logged. Returns nonzero on failure.
 
virtual int save_log_so_far ()
 Save any messages on any endpoints which have been logged so far.
 
virtual vrpn_File_Connectionget_File_Connection (void)
 vrpn_File_Connection implements this as "return this" so it can be used to detect a File_Connection and get the pointer for it
 
void Jane_stop_this_crazy_thing (vrpn_uint32 stop_looking_after)
 This function should be seldom used. It is here for the case of the vrpn_Imager, whose servers do not follow "The VRPN Way" because they try to jam more data into the network than there is bandwidth to support it. As a result, a client may call mainloop() on the connection and have it never return – there is always more data in the network to read, so we never hand control back to the main program. The reason for the name comes from an old U.S. cartoon called "The Jetsons". In it, George Jetson is running on a treadmill when it goes out of control and starts spinning so fast that he can't even run fast enough to reach the controls and turn it off. He cries out to his wife, "Jane! Stop this crazy thing!" The parameter specifies a trigger: if more than the specified number of messages come in on a given input channel during one mainloop() call, the connection should stop looking for more messages. NOTE: this does not guarantee that only this many messages will be received, only that the connection will stop looking for new ones on a given channel once that many have been received (for example, UDP channels will parse all the rest of the messages in a packet before stopping). A value of 0 turns off the limit, and will cause all incoming messages to be handled before returning.
 
vrpn_uint32 get_Jane_value (void)
 
void addReference ()
 Counting references to this connection.
 
void removeReference ()
 
void setAutoDeleteStatus (bool setvalue)
 Specify whether this connection should be deleted automatically when it is no longer need (reference count reaches zero). For connections created by the VRPN code (as is done in get_connection_by_name) these should be auto-deleted. Connections created by user code should not be auto-deleted; that is up to the user to decide when finished. By default, the constructor sets this to FALSE. VRPN code (or user code) can set this to TRUE if it wants the connection to be deleted automatically when the last service on it is deleted.
 

Public Attributes

vrpn_TypeDispatcherd_dispatcher
 Derived classes need access to d_dispatcher in their allocateEndpoint() routine. Several compilers won't give it to them, even if they do inherit publicly. Until we figure that out, d_dispatcher needs to be public.
 

Protected Member Functions

 vrpn_Connection (const char *local_in_logfile_name, const char *local_out_logfile_name, vrpn_EndpointAllocator epa=allocateEndpoint)
 Constructor for server connection. This cannot be called directly any more because vrpn_Connection is an abstract base class. Call vrpn_create_server_connection() to make a server of arbitrary type based on a name.
 
 vrpn_Connection (const char *local_in_logfile_name, const char *local_out_logfile_name, const char *remote_in_logfile_name, const char *remote_out_logfile_name, vrpn_EndpointAllocator epa=allocateEndpoint)
 Constructor for client connection. This cannot be called directly because vrpn_Connection is an abstract base class. Call vrpn_get_connection_by_name() to create a client connection.
 
int delete_endpoint (vrpn_Endpoint *endpoint)
 Deletes the endpoint and NULLs the entry in the list of open endpoints.
 
int compact_endpoints (void)
 Makes sure the endpoint array is set up cleanly for the next pass through.
 
virtual int pack_sender_description (vrpn_int32 which)
 Send the sender description to ALL endpoints.

 Returns message type ID, or -1 if unregistered.
 
int doSystemCallbacksFor (vrpn_HANDLERPARAM, void *)
 
virtual void updateEndpoints (void)
 This function will be called on the mainloop() iteration after *d_endpointAllocator is called, which lets subclasses do initialization. (They can't do so during allocateEndpoint because it's called during the Connection constructor when their constructors haven't executed yet.)
 

Static Protected Member Functions

static vrpn_Endpoint_IPallocateEndpoint (vrpn_Connection *, vrpn_int32 *connectedEC)
 Redefining this and passing it to constructors allows a subclass to use a different subclass of Endpoint. It should do NOTHING but return an endpoint of the appropriate class; it may not access subclass data, since it'll be called from a constructor.
 
static int VRPN_CALLBACK handle_log_message (void *userdata, vrpn_HANDLERPARAM p)
 Routines that handle system messages.
 
static int VRPN_CALLBACK handle_disconnect_message (void *userdata, vrpn_HANDLERPARAM p)

vrpn_int32 d_numConnectedEndpoints
 We need to track the number of connected endpoints separately to properly send out got-first-connection/dropped-last-connection messages. This value is managed by the Endpoints, but we need exactly one copy per Connection, so it's on the Connection.

 Server logging w. multiconnection - TCH July 00 Use one "hidden" endpoint for outgoing logs (?), standard per-endpoint logs with augmented names for incoming. To make a hidden endpoint we create d_endpoints[0] and increment the d_numEndpoints, but DON'T pass it d_numConnectedEndpoints (although it should be safe to do so, since it should never truly become connected, but we might have to "fake" it to get it to log correctly).
