An abstract base class for a family of client device interfaces–including trackers, buttons, dials, and other analog inputs.

bool | forkAsynchronousThread (double poll_time) |
| 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). More...
|
|
CoordinateSystem | getCoordinateSystem () |
| Returns the coordinate system that all devices associated with this client will operate in. Normally, this is CS_default. More...
|
|
double | getLastPollTime () |
| Returns the time (according to the global ClockObject's get_real_time() method) of the last device poll. More...
|
|
bool | isForked () |
| 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. Returns true if the poll occurred, or false if it did not. More...
|
|
| setCoordinateSystem (CoordinateSystem cs) |
| Specifies the coordinate system that all devices associated with this client will operate in. Normally, this is CS_default. More...

Public Member Functions inherited from TypedObject |
TypeHandle | getType () |
| Derived classes should override this function to return get_class_type(). More...
|
|
int | getTypeIndex () |
| 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(). More...
|
|
bool | isExactType (TypeHandle handle) |
| Returns true if the current object is the indicated type exactly. More...
|
|
bool | isOfType (TypeHandle handle) |
| Returns true if the current object is or derives from the indicated type. More...
|
|
Public Member Functions inherited from ReferenceCount |
int | getRefCount () |
| Returns the current reference count. More...
|
|
| ref () |
| 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. More...
|
|
bool | testRefCountIntegrity () |
| Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | testRefCountNonzero () |
| Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
|
|
bool | unref () |
| 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(). More...

An abstract base class for a family of client device interfaces–including trackers, buttons, dials, and other analog inputs.
This provides a common interface to connect to such devices and extract their data; it is used by TrackerNode etc. to put these devices in the data graph.
