SFilter(sgraph[, item_filter, reverse, ...])

Filtered iterator over a SGraph
class SFilter(sgraph, item_filter=None, reverse=False, exclude_ignored=False, include_external=False)

Bases: object

Filtered iterator over a SGraph

This class allows to change the iteration behaviour over the dependency graph stored in SGraph.

Example use:

items = scheduler.items
reversed_items = as_tuple(SFilter(scheduler.sgraph, reverse=True))
procedure_bindings = as_tuple(SFilter(scheduler.sgraph, item_filter=ProcedureBindingItem))
Parameters:

  • sgraph (SGraph) – The graph over which to iterate

  • item_filter (list of Item subclasses, optional) – Only include items that match the provided list of types

  • reverse (bool, optional) – Iterate over the dependency graph in reverse direction

  • exclude_ignored (bool, optional) – Exclude Item objects that have the is_ignored property

  • include_external (bool, optional) – Do not skip ExternalItem in the iterator
