  +--ostore.archive.GuidResult

All Implemented Interfaces:

QuickSerializable

public class GuidResult

extends Object

implements QuickSerializable

The GuidResult class is an object that encapsulates the the GUID generated by the GenerateFragsStage or recoalesed by the RecoalesceBlkStage, the total Erasure code time, the code method time, the Erasure encode or decode time, and the VHashTree time.
