** Implementation level session API: resolve a Placement by hash-ID.

|
|
** This specialised service is intended to be used by PlacementRef,
|
||
|
|
** in order to (re)-access the Placement instance within the session,
|
||
|
|
** given the hash-ID of this placement. An implementation of this
|
||
|
|
** service is available through the SessionServices access mechanism.
|

|
|
**
|
||
|
|
** @see session-impl.hpp implementation of the service
|
||
|
|
** @see session-services.cpp implementation of access
