Shared Objects - Root Object
Each area instance version contains an instance of the area root class that is identified as the root object.
The figure below shows how shared objects are accessed using the root object. The shared objects of an area instance version are accessed initially from an internal session, always by using the reference variable ROOT of the area handle that points to the root object.


The root object has to be defined with the
SET_ROOT instance method of the area handle before the lock is released with the DETACH_COMMIT method of the area handle after change accesses.
Once an area handle has been bound to an existing area instance version, you can obtain a reference to the root object by accessing the ROOT attribute (or even using the GET_ROOT instance method) of the area handle. The root object can then contain and/or return object and data references to additional shared objects of the area instance version.
