Protected Member Functions | |
| void | handleSignal (const FDWriteSignalContext &signal_ctx) |
| Handle an individual signal. | |
Protected Member Functions inherited from Thread | |
| void | mainRun () |
| Does the preRun, run, postRun sequence. | |
| void | closeThread () |
| Sends exit signal to the thread, calls join. This method blocks until thread has exited. Set Thread::has_thread to false. | |
Protected Attributes | |
| FDFrameFifo | infifo |
| Incoming frames (also signal frames) are read from here. | |
| FifoFrameFilter | infilter |
| Write incoming frames here // TODO: add a chain of correcting FrameFilter(s) | |
| BlockingFifoFrameFilter | infilter_block |
| Incoming frames can also be written here. If stack runs out of frames, writing will block. | |
| std::vector< FDWrite * > | slots_ |
| For fast, pointer-arithmetic-based indexing of the slots. | |
| std::list< FDWrite * > | fd_writes |
| For iterating over the FDWrite entries. | |
| fd_set | write_fds |
| fd_set | read_fds |
| File descriptor sets used by select. | |
| int | nfds |
| Max file descriptor number. | |
| struct timeval | timeout |
Protected Attributes inherited from Thread | |

| Name of the thread. | |
| bool | has_thread |
| true if thread has been started | |
| bool | stop_requested |
| bool | thread_joined |
| std::mutex | start_mutex |
| Mutex protecting start_condition. | |
| std::condition_variable | start_condition |
| Notified when the thread has been started. | |
| std::mutex | mutex |
| Mutex protecting the condition variable and signal queue. | |
| std::condition_variable | condition |
| Condition variable for the signal queue (triggered when all signals processed). Not necessarily used by all subclasses. | |
| std::mutex | loop_mutex |
| Protects thread's main execution loop (if necessary) | |
| std::deque< SignalContext > | signal_fifo |
| Signal queue (fifo). Redefine in child classes. | |
| bool | loop |
| Use this boolean to control if the main loop in Thread:run should exit. | |
| int | core_id |
| pthread_attr_t | thread_attr |
| Thread attributes, pthread_* way. | |

API method: stops the thread.
Like Thread::stopCall() but does not block. Waiting for the thread to join is done in Thread::waitStoppedCall()
Reimplemented from Thread.
