traverse_downstream_graph
- omni.graph.core.traverse_downstream_graph(prims: List[Prim], attribute_predicate: Optional[Callable[[Attribute], bool]] = None, node_callback: Optional[Callable[[Node], None]] = None) Set[Node]
Traverses the nodes downstream from the input nodes and apply the predicate on visited nodes.
- Parameters
prims – The list of starting point nodes for the traversal.
attribute_predicate – Function taking an Attribute as parameter and returning bool. If True, connections to this attribute are evaluated, otherwise they are skipped.
node_callback – Function taking a Node as parameter. Allows for custom logic to be applied to visited nodes.
- Returns
Returns the set of visited nodes.
- Raises
og.OmniGraphError if the list of prims contains an invalid prim, or the prims do not all belong to the same graph. –
