| * An object that creates new threads on demand. Using thread factories removes |
| * hardwiring of calls to new Thread, enabling applications to use special thread |
| * subclasses, priorities, etc. |
| * |
| * The simplest implementation of this interface is just: |
| * |
| * class SimpleThreadFactory : public ThreadFactory { |
| * public: |
| * Thread* newThread( Runnable* r ) { |
| * return new Thread(r); |
| * } |
| * } |
| * |
| * The Executors.defaultThreadFactory() method provides a more useful simple |
| * implementation, that sets the created thread context to known values before |
| * returning it. |
| * |
| * @since 1.0 |
