DDS — clone + deref

ref-1041: clone + deref
Issue [THALES]
For performance, it seems good to offer a combined operation clone + deref that returns the instantiated cell instead the ObjectReference
Proposal [THALES]
Add such a method on ObjectRoot and also in the implied IDL
Concrete changes:
IDL
ObjectRoot {
...
ObjectRoot clone_object(
in CacheAccess access,
in ObjectScope scope,
in RelatedObjectDepth depth)
raises (
ReadOnlyMode,
AlreadyClonedInWriteMode);
Foo {
...
Foo clone_foo(
in CacheAccess access,
in ObjectScope scope,
in ReletedObjectDepth depth)
raises (
ReadOnlyMode,
AlreadyClonedInWriteMode);
in section 3.1.6.3.11 ObjectRoot
in the table, add the clone_object operation, by adding the following:
clone_object ObjectRoot
access CacheAccess
scope ObjectScope
depth integer
in the following text, in the list starting with "it offers methods to":
insert a second bullet, with the following contents:
"clone and instantiate the object in the same operation (clone_object), this operations takes the same parameters as the previous one, but returns an ObjectRoot instead of an ObjectReference; it corresponds exactly to the sequence of clone followed by CacheAccess::deref on the reference returned by the clone operation;"
in section 3.1.6.5.1 Read Mode
item #2, change "(ObjectRoot::clone)" to "(ObjectRoot::clone or clone_object)"
in section 3.1.6.5.2 Write Mode
item #2, change "(ObjectRoot::clone)" to "(ObjectRoot::clone or clone_object)"
