Atoms, Tasks and Retries

An atom is the smallest unit in taskflow which acts as the base for other classes. Atoms have a name and a version (if applicable). Atom is expected to name desired input values (requirements) and name outputs (provided values), see arguments_and_results page for complete reference about it.

Task

A task (derived from an atom) is the smallest possible unit of work that can have an execute & rollback sequence associated with it.

Retry

A retry (derived from an atom) is a special unit that handles flow errors, controlls flow execution and can retry it with another parameters if needed.
