Class CodSlice

java.lang.Object
  orca.shirako.kernel.Slice
      orca.cod.CodSlice

All Implemented Interfaces:

java.lang.Cloneable, ISerialize, ISlice

Direct Known Subclasses:

AuthorityCodSlice

public class CodSlice
extends Slice

Attributes and global state for a COD slice. One CodSlice object is attached to each COD instance of slices.Slice.

On a Service Manager, the CodSlice is created explicitly and primed with with desired parameters for the Slice. CodSlice installs these parameters in the Slice properties, and they are passed to the Authority in the Slice property list.

On an Authority, the CodSlice is created on first allocation of resources for the slice. Its attributes are determined from the Slice properties and their interaction with Site parameters and policies.
