Member Function Documentation

[signal] void TaskInterface::done(bool success)

Emit this signal from the TaskAdapter<Task>'s subclass, when the Task is finished. Pass true as a success argument when the task finishes with success; otherwise, when an error occurs, pass false.

[pure virtual protected] void TaskInterface::start()

This method is called by the running TaskTree for starting the Task instance. Reimplement this method in TaskAdapter<Task>'s subclass in order to start the associated task.

Use TaskAdapter::task() to access the associated Task instance.
