Issue 10729: Cache should have a getter to obtain its related DomainParticipant. (data-distribution-rtf)
Source: PrismTech (Mr. Erik Hendriks, erik.hendriks(at)prismtech.com)
Nature: Revision
Severity: 
Summary: Problem:

Currently it is not possible to navigate from a Cache to its underlying DomainParticipant. Such navigation may be convenient because the underlying DomainParticipant may be needed to manage statuses, control connectivity, change QoS settings and assert liveliness.

Solution:

Add an attribute to the Cache that refers to the underlying DomainParticipant.

Section 3.1.6.2, Figure 3-4: Add a DomainParticipant class and a reference from the Cache to that DomainParticipant class. Name the reference "the_participant".

Section 3.1.6.3.4: Add the following entry to the table:

Cache
attributes
the_participant	DDS::DomainParticipant

Section 3.1.6.3.4
Replace:

·	the state of the cache with respect to the underlying Pub/Sub infrastructure (pubsub_state), as well as the related Publisher (the_publisher) and Subscriber (the_subscriber).

With:

·	the state of the cache with respect to the underlying Pub/Sub infrastructure (pubsub_state), as well as the related DomainParticipant (the_participant), Publisher (the_publisher) and Subscriber (the_subscriber).

Section 3.2.1.2: Add to the IDL of the Cache interface the following line:

readonly attribute DDS::DomainParticipant     the_participant;
