## Detailed Description

Data source with own thread.

A data source with a thread of its own

## Constructor & Destructor Documentation

ThreadedSource | ( | const char * | format = `"slin"` | ) |
| inline explicit protected

Threaded Source constructor

Parameters

  format | Name of the data format, default "slin" (Signed Linear)

## Member Function Documentation

virtual void cleanup | ( |  | ) |
| protected virtual

The cleanup after thread method, deletes the source if already dereferenced and set for asynchronous deletion

virtual void destroyed | ( |  | ) |
| virtual

The destruction notification, checks that the thread is gone

Reimplemented from DataSource.

bool looping | ( | bool | runConsumers = `false` | ) | const
| protected

Check if the calling thread should keep looping the worker method

Parameters

  runConsumers | True to keep running as long consumers are attached

Returns
  True if the calling thread should remain in the run() method

virtual void run | ( |  | ) |
| protected pure virtual

The worker method. You have to reimplement it as you need

bool running | ( |  | ) | const

Check if the data thread is running

Returns
  True if the data thread was started and is running

bool start | ( | const char * | name = `"ThreadedSource"`,
|  | Thread::Priority | prio = `Thread::Normal`
| ) |  |

Starts the worker thread

Parameters

  name | Static name of this thread
  prio | Thread's priority

Returns
  True if started, false if an error occured

void stop | ( |  | ) |

Stops and destroys the worker thread if running

Thread* thread | ( |  | ) | const

Return a pointer to the worker thread

Returns
  Pointer to running worker thread or NULL
