Member Function Documentation

◆ once()

void KatanaGripperThread::once ( )
virtual

Execute an action exactly once.

This code is executed once and only once right after the thread is started before loop() is called. This is useful if you want to implement an one-shot background job. Just implement once() and leave loop() untouched. Start the thread and detach it and it will just do its job and then die automatically. If you use set_delete_on_exit(true) even the Thread instance will be automatically deleted.

Reimplemented from fawkes::Thread.
