Issue 10737: How are deleted objects treated in a CacheBase and a Selection (data-distribution-rtf)
Source: PrismTech (Mr. Erik Hendriks, erik.hendriks(at)prismtech.com)
Nature: Revision
Severity: 
Summary: Problem:

It needs to be clarified how deleted objects are treated in a CacheBase and a Selection. In the update round in which they are reported as being deleted, are they still part of the members of that CacheBase/Selection or not? (See also section 3.1.6.4.1 last bullet.)

Solution:

Since deleted objects are no longer alive, we propose not to mention them in the members attribute of CacheBases/Selections. In the update round in which they become deleted they will be reported as being deleted in those CacheBases/Selections, but this deletion is executed immediately.

Section 3.1.6.3.2
Replace:

·	"A list of (untyped) objects that are contained in this CacheBase. To obtain objects by type, see the get_objects method in the typed ObjectHome.

With:

·	A list of (untyped) objects (excluding the ones that are marked as deleted) that are contained in this CacheBase. To obtain objects by type, see the get_objects method in the typed ObjectHome.

Section 3.1.6.3.7
Replace:

·	obtain from a CacheBase a (typed) list of all objects that match the type of the selected ObjectHome (get_objects). For example the type ObjectRoot[ ] will be substituted by a type Foo[] in a FooHome.

With:

·	obtain from a CacheBase a (typed) list of all objects (excluding the ones that are marked as deleted) that match the type of the selected ObjectHome (get_objects). For example the type ObjectRoot[ ] will be substituted by a type Foo[ ] in a FooHome.

Section 3.1.6.3.9:
Replace:

·	the list of the objects that are part of the selection (members).

With:

·	the list of the objects (excluding the ones that are marked as deleted and the ones that no longer pass the filter) that are part of the selection (members).

How are deleted objects treated in a CacheBase and a Selection
It needs to be clarified how deleted objects are treated in a CacheBase and a Selection.

Problem:

It needs to be clarified how deleted objects are treated in a CacheBase and a Selection. In the update round in which they are reported as being deleted, are they still part of the members of that CacheBase/Selection or not? (See also section 3.1.6.4.1 last bullet.)

Solution:

Since deleted objects are no longer alive, we propose not to mention them in the members attribute of CacheBases/Selections. In the update round in which they become deleted they will be reported as being deleted in those CacheBases/Selections, but this deletion is executed immediately.
