TaskTree

TaskTree - generic solution for automatic management of asynchronous tasks (C++)

TaskTree automatically manages a chain (or a tree) of asynchronous tasks of mixed types.

The recipe on how to run and manage the conglomerate of tasks is described in a declarative way in C++.

The recipes are enclosed in copyable value-type objects and may be run many times, or be part of more general recipes.

The TaskTree is broadly used in QtCreator, for executing Build / Deploy configurations, Locator filter, Clang tool, Autotests, driving Axivion plugin's communication and much more...

The TaskTree's implementation is separated from the QtCreator specific code and may already serve as a general purpose solution outside of QtCreator.
