cutcutcodec.core.compilation.graph_to_tree.update_trees

cutcutcodec.core.compilation.graph_to_tree.update_trees(graph: MultiDiGraph) → None[source]

Update on each node the tree attribute.

From the assembly graph, this function reconstructs the dynamic instances and is able to perform the calculations. By adding to each node the attribute tree, it allows not only to keep the graph structure but also to recalculate only the parts that need to be changed.

The operation are applies in-place.

Parameters

graphnetworkx.MultiDiGraph: The assembly graph who is going to have the updated tree attributes.
