Member Enumeration Documentation

enum PDG_WorkItemSerialization::CheckpointType

Enumeration of checkpoint save types, which are used to determine which set of fields to write to the JSON object for a serialized work item

Enumerator
eCheckpointNone	Serialize all fields – no checkpointing is in progress.
eCheckpointInitial	Serialize the initial baseline fields for the work item.
eCheckpointUpdate	Serialize only fields that can be updated dynamically, when the work item cooks

Definition at line 62 of file PDG_WorkItemSerialization.h.
