A container object for construct new PDG work items, by passing a pdg.WorkItemOptions
object or a key/value arguments to the addWorkItem method
Methods
addWorkItem(options=None, **kwargs)
→ pdg.WorkItem
Constructs a new work item and adds it to the holder. This function can either take a pdg.WorkItemOptions object, or a keyword arguments matching the supported values in the work item options object.
For example:
# Using keyword arguments item_holder.addWorkItem(name="example", index=5) # Using an options object options = pdg.WorkItemOptions() options.name = "otherexample" options.cloneResultData = True item_holder.addWorkItem(options) # Combination item_holder.addWorkItem(options, name='overridename')
addDependency(child, parent)
Used when this object is passed to a mapping callback on a node.
Makes the child pdg.WorkItem object depend on the parent work item object.
Tip
The order of the arguments only matters when you're creating a dependency between two work items in the same node. Otherwise, the code will notice if you try to make an upstream item dependent on a downstream item, and flip the order for you.
isEmpty
: bool
Property
True if the holder is empty, else False.
