Houdini 19.0 Executing tasks with PDG/TOPs pdg

pdg.ConstWorkItemList class

A list of read-only work items

This class wraps a list of work items and provides the same interface as a standard Python list. Work items in the list are only converted to pdg.WorkItem objects when they're accessed. The work items in the list cannot be modified, e.g. attempting to write to their attributes will be result in an exception.
