For each instance, the middleware internally maintains an instance state. The instance state can be:
The precise behavior events that cause the instance state to change depends on the setting of the OWNERSHIP QoS:
The instance state available in the com.rti.dds.subscription.SampleInfo is a snapshot of the instance state of the instance at the time the collection was obtained (i.e. at the time read or take was called). The instance state is therefore the same for all samples in the returned collection that refer to the same instance.
