Static Public Member Functions

static TypeHandle getClassType ()
 
- Static Public Member Functions inherited from Thread
static Thread bindThread (str name, str sync_name)
 Returns a new Panda Thread object associated with the current thread (which has been created externally). More...
 
static considerYield ()
 Possibly suspends the current thread for the rest of the current epoch, if it has run for enough this epoch. More...
 
static forceYield ()
 Suspends the current thread for the rest of the current epoch. More...
 
static TypeHandle getClassType ()
 
static int getCurrentPipelineStage ()
 Returns the integer pipeline stage associated with the current thread. More...
 
static Thread getCurrentThread ()
 Returns a pointer to the currently-executing Thread object. More...
 
static Thread getExternalThread ()
 Returns a pointer to the "external" Thread object–this is a special Thread object that corresponds to any thread spawned outside of Panda's threading interface. More...
 
static Thread getMainThread ()
 Returns a pointer to the "main" Thread object–this is the Thread that started the whole process. More...
 
static bool isSimpleThreads ()
 Returns true if Panda is currently compiled for "simple threads", which is to say, cooperative context switching only, reducing the need for quite so many critical section protections. More...
 
static bool isThreadingSupported ()
 Returns true if threading support has been compiled in and enabled, or false if no threading is available (and Thread::start() will always fail). More...
 
static bool isTrueThreads ()
 Returns true if a real threading library is available that supports actual OS-implemented threads, or false if the only threading we can provide is simulated user-space threading. More...
 
static prepareForExit ()
 Should be called by the main thread just before exiting the program, this blocks until any remaining thread cleanup has finished. More...
 
static sleep (double seconds)
 Suspends the current thread for at least the indicated amount of time. More...
 
static writeStatus (Ostream out)
 
- Static Public Member Functions inherited from TypedReferenceCount
static TypeHandle getClassType ()
 
- Static Public Member Functions inherited from TypedObject
static TypeHandle getClassType ()
