Kinds of presentation "access scope".
Access scope determines the largest scope spanning the entities for which the order and coherency of changes can be preserved.
INSTANCE_PRESENTATION_QOS |
[default] Scope spans only a single instance.
Indicates that changes to one instance need not be coherent nor ordered with respect to changes to any other instance. In other words, order and coherent changes apply to each instance separately. |
TOPIC_PRESENTATION_QOS | Scope spans to all instances within the same DDS::DataWriter (or DDS::DataReader), but not across instances in different DDS::DataWriter (or DDS::DataReader). |
GROUP_PRESENTATION_QOS | Scope spans to all instances belonging to DDS::DataWriter (or DDS::DataReader) entities within the same DDS::Publisher (or DDS::Subscriber). |
HIGHEST_OFFERED_PRESENTATION_QOS | This value only applies to a DDS::Subscriber. The DDS::Subscriber will use the access scope specified by each remote DDS::Publisher. |
static System::String ^ DDS::PresentationQosPolicy::get_presentation_qos_policy_name | ( | ) | [inline, static, inherited] |
