enum dds::core::policy::PresentationAccessScopeKind_def::type

The underlying enum type.

Enumerator
INSTANCE	[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	Scope spans all instances within the same dds::pub::DataWriter, but not across instances in different dds::pub::DataWriter entities.
GROUP	Scope spans all instances belonging to dds::pub::DataWriter entities within the same dds::pub::Publisher.
HIGHEST_OFFERED	This value only applies to a dds::sub::Subscriber. The dds::sub::Subscriber will use the access scope specified by each remote dds::pub::Publisher.
