Houdini 19.0 Executing tasks with PDG/TOPs pdg

pdg.attribFlag module

The enumeration of work item attribute flags

This enum contains the possible types for a flag metadata stored on a pdg.WorkItem attribute.

Values

pdg.attribFlag.NoFlags

The attribute has no flags set.

pdg.attribFlag.All

The attribute has all flags set.

pdg.attribFlag.NoCopy

The attribute is marked as not being copied onto downstream work items.

pdg.attribFlag.EnvExport

The attribute value will be exported to the environment when the work item is executed out of process.

pdg.attribFlag.ReadOnly

The attribute value can only be read, not modified.

pdg.attribFlag.Internal

The attribute is a built in created by PDG.

pdg.attribFlag.Operator

The attribute refers to an operator path.

pdg.attribFlag.Transfer

The attribute refers to a file path that should be transferred to the remote scheduler directory when the work item cooks.

pdg.attribFlag.Dependent

The attribute is copied onto internal dependents within the same node, if they don’t already have a value for the same attribute.

pdg.attribFlag.NoDirty

The attribute does not cause work items to be dirtied when its value changes during item regeneration. Attribute adds/deletes, or changes to other attributes or work item intrinsics, will still cause the work item to be dirtied.

pdg.attribFlag.InputFile

The attribute refers to a file that should be treated as an extra input to the work item. If the file changes on disk between cooks, then any cached outputs for the work item are also invalidated.
