Interface RawContainerHandle
- All Superinterfaces:
ContainerHandle
- All Known Implementing Classes:
BaseContainerHandle
RawContainerHandle is the form of ContainerHandle that is used within
the raw store. This allows the raw store to have a handle on dropped
container without exposing this to the external interface, which is not
allowed to get back a handle on a dropped container

NORMAL
static final int NORMALA container can be in 4 states: non_existent - this is represented by a null ContainerHandle NORMAL - this is the normal case, container has been created and is not dropped. DROPPED - container has been dropped, but is not known whether the drop has been committed or not COMMITTED_DROP - container has been dropped and has committed. To everyone else except recovery, this state is equivalent to NON_EXISTENT- See Also:

DROPPED
