polaris.run.graph.StepGraph

class polaris.run.graph.StepGraph(nodes: Dict[str, StepNode])

Which steps have to run before which.

Variables:

nodes (dict of polaris.run.graph.StepNode) – The steps, keyed by path, in the order setup listed them. The order is the tie-break for choosing among steps that could all run, and it is stable, so two runs of the same work make the same choices.

__init__(nodes: Dict[str, StepNode])

Methods

__init__(nodes)
dependents(path)	The steps that name this one, directly, among their requirements.
descendants(path)	Every step that this one is required by, directly or through others.
