Public Member Functions | |
VrpnClient (string server_name) | |
bool | forkAsynchronousThread (double poll_time) |
Forks a separate thread to do all the polling of connected devices. | |
CoordinateSystem | getCoordinateSystem () |
Returns the coordinate system that all devices associated with this client will operate in. | |
double | getLastPollTime () |
Returns the time (according to the global ClockObject's get_real_time() method) of the last device poll. | |
int | getRefCount () |
Returns the current reference count. | |
string | getServerName () |
Returns the name of the server as passed to the VrpnClient constructor. | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. | |
bool | isConnected () |
Returns true if the connection is established succesfully, false otherwise. | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. | |
bool | isForked () |
Returns true if the ClientBase has been forked (and, therefore, poll() does not need to be called), false otherwise. | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. | |
bool | isValid () |
Returns true if everything seems to be kosher with the server (even if there is no connection), or false otherwise. | |
bool | poll () |
Initiates a poll of the client devices, if we are not forked and if we have not already polled this frame. | |
ref () | |
Explicitly increments the reference count. | |
setCoordinateSystem (CoordinateSystem cs) | |
Specifies the coordinate system that all devices associated with this client will operate in. | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. | |
bool | unref () |
Explicitly decrements the reference count. | |
write (ostream out, int indent_level) | |
Writes a list of the active devices that the VrpnClient is currently polling each frame. | |
write (ostream out) | |
Writes a list of the active devices that the VrpnClient is currently polling each frame. | |
Static Public Member Functions | |
static TypeHandle | getClassType () |
A specific ClientBase that connects to a VRPN server and records information on the connected VRPN devices.
VrpnClient | ( | string | server_name | ) |
bool forkAsynchronousThread | ( | double | poll_time | ) | [inherited] |
Forks a separate thread to do all the polling of connected devices.
The forked thread will poll after every poll_time seconds has elapsed. Returns true if the fork was successful, or false otherwise (for instance, because we were already forked, or because asynchronous threads are disabled).
static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from ClientBase.
CoordinateSystem getCoordinateSystem | ( | ) | [inherited] |
Returns the coordinate system that all devices associated with this client will operate in.
Normally, this is CS_default.
double getLastPollTime | ( | ) | [inherited] |
Returns the time (according to the global ClockObject's get_real_time() method) of the last device poll.
int getRefCount | ( | ) | [inherited] |
Returns the current reference count.
string getServerName | ( | ) |
Returns the name of the server as passed to the VrpnClient constructor.
TypeHandle getType | ( | ) | [inherited] |
Reimplemented in AnimChannelBase.
int getTypeIndex | ( | ) | [inherited] |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
This is equivalent to get_type().get_index().
bool isConnected | ( | ) |
Returns true if the connection is established succesfully, false otherwise.
bool isExactType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is the indicated type exactly.
bool isForked | ( | ) | [inherited] |
Returns true if the ClientBase has been forked (and, therefore, poll() does not need to be called), false otherwise.
bool isOfType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is or derives from the indicated type.
bool isValid | ( | ) |
Returns true if everything seems to be kosher with the server (even if there is no connection), or false otherwise.
bool poll | ( | ) | [inherited] |
Initiates a poll of the client devices, if we are not forked and if we have not already polled this frame.
Returns true if the poll occurred, or false if it did not.
ref | ( | ) | [inherited] |
Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
setCoordinateSystem | ( | CoordinateSystem | cs | ) | [inherited] |
Specifies the coordinate system that all devices associated with this client will operate in.
Normally, this is CS_default.
bool testRefCountIntegrity | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.
Returns true if ok, false otherwise.
Reimplemented in NodeReferenceCount, CachedTypedWritableReferenceCount, and NodeCachedReferenceCount.
bool testRefCountNonzero | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus.
Returns true if ok, false otherwise.
bool unref | ( | ) | [inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
Reimplemented in GeomVertexArrayFormat, and GeomVertexFormat.
Writes a list of the active devices that the VrpnClient is currently polling each frame.
write | ( | ostream | out | ) |
Writes a list of the active devices that the VrpnClient is currently polling each frame.
