Instance Method Details

- (Array<RailsWorkflow::Operation>) build_dependencies(operation)

This methods get's operations that depends on given one. Operation::DependencyResolver resolves operation template dependencies but we can define dependencies not only by template but by some other business logic on process level. That is why I splitted operation dependencies on process and operation level

Parameters:

  • operation (RailsWorkflow::Operation) —

    which changed status; process template operations that depends on given operation's template (and it's status) will be build.

Returns:
