public interface CDOPackageUnit extends Comparable<CDOPackageUnit>
packages
that are registered with a package registry
and that can only be serialized as a whole.
A package unit is the granule of committing or lazy loading packages. It contains some overall information like
type
, state
, commit time
and nested package
info
objects that describe all the nested packages.
