Process chain consistency checkers
A process chain consistency checker plugin is a function that checks if an execute action can be added to a process chain or if adding it would lead to inconsistencies that render the process chain inexecutable.
The function is called before the execute action is converted to an executable and before it is added to the process chain. It takes a list of executables that have been collected so far during process chain generation, the execute action that is about to be converted, the workflow from which the process chain is being created, and a Vert.x instance.
true if the execute action can safely be converted and added to
the list of executables to make up a new process chain, or
false if adding
it would lead to a process chain that could not be executed later.
Steep will not discard actions that a consistency checker plugin has rejected. Instead, it will try to add them to another process chain later. At this point, the plugin will be called again.
If required, the function can be a suspend function.
