Public Member Functions | |
VrpnClient (const string &server_name) | |
virtual TypeHandle | force_init_type () |
const string & | get_server_name () const |
Returns the name of the server as passed to the VrpnClient constructor. | |
virtual TypeHandle | get_type () const |
bool | is_connected () const |
Returns true if the connection is established successfully, false otherwise. | |
bool | is_valid () const |
Returns true if everything seems to be kosher with the server (even if there is no connection), or false otherwise. | |
void | write (ostream &out, int indent_level=0) const |
Writes a list of the active devices that the VrpnClient is currently polling each frame. | |
Static Public Member Functions | |
static double | convert_to_secs (struct timeval msg_time) |
Little inline function to convert a struct timeval to only seconds. | |
static TypeHandle | get_class_type () |
static void | init_type () |
This function is declared non-inline to work around a compiler bug in g++ 2.96. | |
Protected Member Functions | |
virtual bool | disconnect_device (TypeHandle device_type, const string &device_name, ClientDevice *device) |
Removes the device, which is presumably about to destruct, from the list of connected devices, and frees any data required to support it. | |
virtual void | do_poll () |
Implements the polling and updating of connected devices, if the ClientBase requires this. | |
virtual | PT (ClientDevice) make_device(TypeHandle device_type |

double VrpnClient::convert_to_secs | ( | struct timeval | msg_time | ) | [inline, static] |
Little inline function to convert a struct timeval to only seconds.

bool VrpnClient::disconnect_device | ( | TypeHandle | device_type, |
const string & | device_name, | ||
ClientDevice * | device | ||
) | [protected, virtual] |
Removes the device, which is presumably about to destruct, from the list of connected devices, and frees any data required to support it.
This device will no longer receive automatic updates with each poll.
The return value is true if the device was disconnected, or false if it was unknown (e.g. it was disconnected previously).
Reimplemented from ClientBase.

void VrpnClient::do_poll | ( | ) | [protected, virtual] |
Implements the polling and updating of connected devices, if the ClientBase requires this.
This may be called in a sub-thread if fork_asynchronous_thread() was called; otherwise, it will be called once per frame.

const string & VrpnClient::get_server_name | ( | ) | const [inline] |
Returns the name of the server as passed to the VrpnClient constructor.
Definition at line 24 of file vrpnClient.I.
static void VrpnClient::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
