Detailed Description

To implement a custom task adapter, derive your adapter from the TaskAdapter<Task> class template. TaskAdapter automatically creates and destroys the custom task instance and associates the adapter with a given Task type.

Member Function Documentation

[signal] void TaskInterface::done(Tasking::DoneResult result)

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

[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.
