| tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::ThreadPool | ( | LockFreeMultiThreadedNodePlayer & | p | ) |
Constructs a ThreadPool for a given LockFreeMultiThreadedNodePlayer.
Definition at line 86 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
|
pure virtual |
Subclasses should implement this to clear all the threads.
Implemented in tracktion::graph::ThreadPoolCV, tracktion::graph::ThreadPoolRT, tracktion::graph::ThreadPoolHybrid, tracktion::graph::ThreadPoolSem< SemaphoreType >, and tracktion::graph::ThreadPoolSemHybrid< SemaphoreType >.

| bool tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::isFinalNodeReady | ( | ) |
Returns true if all the Nodes have been processed.
Definition at line 153 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
| bool tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::process | ( | ) |
Process the next chain of Nodes.
Returns true if at least one Node was processed, false if no Nodes were processed. You can use this to determine how long to pause/wait for before processing again.
Definition at line 167 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
| void tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::resetExitSignal | ( | ) |
Signals the pool that all the threads should continue to run and not exit.
Definition at line 130 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
| void tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::setCurrentNode | ( | LockFreeMultiThreadedNodePlayer::PreparedNode * | nodeInUse | ) |
Sets the current PreparedNode in use.
This should live as long as the threads are running once set.
Definition at line 176 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
| bool tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::shouldExit | ( | ) | const |
Returns true if all the threads should exit.
Definition at line 136 of file tracktion_LockFreeMultiThreadedNodePlayer.h.
| bool tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPool::shouldWait | ( | ) |
Returns true if there are no free Nodes to be processed and the calling thread should wait until there are Nodes ready.

Called by the player when more than one Node becomes available to process.
Subclasses should use this to try and get a thread to call process as soon as possible.
Implemented in tracktion::graph::ThreadPoolCV, tracktion::graph::ThreadPoolHybrid, tracktion::graph::ThreadPoolSem< SemaphoreType >, tracktion::graph::ThreadPoolSemHybrid< SemaphoreType >, and tracktion::graph::ThreadPoolRT.

Called by the player when the audio thread has no free Nodes to process.
Subclasses should can use this to either spin, pause or wait until a Node does become free or isFinalNodeReady returns true.
Implemented in tracktion::graph::ThreadPoolCV, tracktion::graph::ThreadPoolRT, tracktion::graph::ThreadPoolHybrid, tracktion::graph::ThreadPoolSem< SemaphoreType >, and tracktion::graph::ThreadPoolSemHybrid< SemaphoreType >.
