bool Thread::is_simple_threads ( ) [inline, static, inherited]

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.

This is not necessarily the opposite of "true threads", since one possible implementation of simple threads is via true threads with mutex protection to ensure only one runs at a time.

Definition at line 221 of file thread.I.

bool Thread::is_started ( ) const [inline, inherited]

Returns true if the thread has been started, false if it has not, or if join() has already been called.

Definition at line 275 of file thread.I.

bool Thread::is_threading_supported ( ) [inline, static, inherited]

bool Thread::is_true_threads ( ) [inline, static, inherited]

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.

Definition at line 201 of file thread.I.

Referenced by GraphicsEngine::render_frame(), and NodePath::verify_complete().

void Thread::join ( ) [inline, inherited]

Blocks the calling process until the thread terminates.

If the thread has already terminated, this returns immediately.

Definition at line 298 of file thread.I.

Referenced by AsyncTaskChain::do_stop_threads().

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void Thread::output ( ostream &  out) const [virtual, inherited]

Outputs the Namable.

This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

Reimplemented from Namable.

Definition at line 172 of file thread.cxx.

void Thread::output_blocker ( ostream &  out) const [inherited]

Writes a description of the mutex or condition variable that this thread is blocked on.

Writes nothing if there is no blocker, or if we are not in DEBUG_THREADS mode.

Definition at line 185 of file thread.cxx.

void Thread::preempt ( ) [inline, inherited]

Indicates that this thread should run as soon as possible, preemptying any other threads that may be scheduled to run.

This may not be implemented on every platform.

Definition at line 315 of file thread.I.

void Thread::prepare_for_exit ( ) [inline, static, inherited]

Should be called by the main thread just before exiting the program, this blocks until any remaining thread cleanup has finished.

Definition at line 341 of file thread.I.

Referenced by PandaFramework::close_framework(), and GraphicsEngine::remove_all_windows().

void ReferenceCount::ref ( ) const [inline, 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.

void Thread::set_min_pipeline_stage ( int  min_pipeline_stage) [inline, inherited]

Sets this thread's pipeline stage number to at least the indicated value, unless it is already larger.

See set_pipeline_stage().

Definition at line 96 of file thread.I.

References Thread::set_pipeline_stage().

void Thread::set_pipeline_stage ( int  pipeline_stage) [inherited]

Specifies the Pipeline stage number associated with this thread.

The default stage is 0 if no stage is specified otherwise.

This must be a value in the range [0 .. pipeline->get_num_stages() - 1]. It specifies the values that this thread observes for all pipelined data. Typically, an application thread will leave this at 0, but a render thread may set it to 1 or 2 (to operate on the previous frame's data, or the second previous frame's data).

void Thread::set_pstats_callback ( Thread::PStatsCallback pstats_callback) [inline, inherited]

Stores a PStats callback to be associated with this thread.

This is used internally by the PStatClient; you should not need to call this directly.

Definition at line 365 of file thread.I.

void Thread::set_pstats_index ( int  pstats_index) [inline, inherited]

Stores a PStats index to be associated with this thread.

This is used internally by the PStatClient; you should not need to call this directly.

Definition at line 353 of file thread.I.

void Thread::sleep ( double  seconds) [inline, static, inherited]

Suspends the current thread for at least the indicated amount of time.

It might be suspended for longer.

Referenced by ModelLoadRequest::do_task(), TextureReloadRequest::do_task(), PStatServer::main_loop(), and MayaApi::MayaApi().

bool Thread::start ( ThreadPriority  priority,
bool  joinable 
) [inherited]

Starts the thread executing.

It is only valid to call this once.

The thread will begin executing its thread_main() function, and will terminate when thread_main() returns.

priority is intended as a hint to the relative importance of this thread. This may be ignored by the thread implementation.

joinable should be set true if you intend to call join() to wait for the thread to terminate, or false if you don't care and you will never call join(). Note that the reference count on the Thread object is incremented while the thread itself is running, so if you just want to fire and forget a thread, you may pass joinable = false, and never store the Thread object. It will automatically destruct itself when it finishes.

The return value is true if the thread is successfully started, false otherwise.

Definition at line 237 of file thread.cxx.

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

Returns true if ok, false otherwise.

Definition at line 252 of file referenceCount.I.

References ReferenceCount::do_test_ref_count_nonzero().

Referenced by CopyOnWritePointer::test_ref_count_nonzero().

bool ReferenceCount::unref ( ) const [inline, virtual, 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.

void ReferenceCount::weak_ref ( WeakPointerToVoid ptv) [inline, inherited]
