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. More... | |
virtual TypeHandle | get_type () const |
bool | is_connected () const |
Returns true if the connection is established successfully, false otherwise. More... | |
bool | is_valid () const |
Returns true if everything seems to be kosher with the server (even if there is no connection), or false otherwise. More... | |
void | write (ostream &out, int indent_level=0) const |
Writes a list of the active devices that the VrpnClient is currently polling each frame. More... | |
![]() | |
bool | fork_asynchronous_thread (double poll_time) |
Forks a separate thread to do all the polling of connected devices. More... | |
CoordinateSystem | get_coordinate_system () const |
Returns the coordinate system that all devices associated with this client will operate in. More... | |
double | get_last_poll_time () const |
Returns the time (according to the global ClockObject's get_real_time() method) of the last device poll. More... | |
bool | is_forked () const |
Returns true if the ClientBase has been forked (and, therefore, poll() does not need to be called), false otherwise. More... | |
bool | poll () |
Initiates a poll of the client devices, if we are not forked and if we have not already polled this frame. More... | |
PT (ClientDevice) get_device(TypeHandle device_type | |
void | set_coordinate_system (CoordinateSystem cs) |
Specifies the coordinate system that all devices associated with this client will operate in. More... | |

int | get_best_parent_from_Set (const std::set< int > &) const |
int | get_type_index () const |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. More... | |
bool | is_exact_type (TypeHandle handle) const |
Returns true if the current object is the indicated type exactly. More... | |

bool | has_weak_list () const |
Returns true if this particular ReferenceCount object has a WeakReferenceList created, false otherwise. More... | |
void | local_object () |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack. More... | |
void | ref () const |
Explicitly increments the reference count. More... | |
bool | test_ref_count_integrity () const |
Does some easy checks to make sure that the reference count isn't completely bogus. More... | |
bool | test_ref_count_nonzero () const |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. More... | |
virtual bool | unref () const |
Explicitly decrements the reference count. More... | |
void | weak_ref (WeakPointerToVoid *ptv) |
Adds the indicated PointerToVoid as a weak reference to this object. More... | |
void | weak_unref (WeakPointerToVoid *ptv) |
Removes the indicated PointerToVoid as a weak reference to this object. More... | |
