|A sequence of unicast communication settings. |
During discovery, each DDSEntity announces to remote applications a list of (up to 4) unicast addresses to which the remote application should send data (either user data packets or reliable protocol meta-data such as ACK/NACKs and heartbeats).
By default, the list of addresses is populated automatically with values obtained from the enabled transport plug-ins allowed to be used by the Entity (see DDS_TransportBuiltinQosPolicy and DDS_TransportSelectionQosPolicy). Also, the associated ports are automatically determined (see DDS_RtpsWellKnownPorts_t).
Use this QoS policy to manually set the receive address list for an Entity. You may optionally set a port to use a non-default receive port as well. Only the first 4 addresses will be used.
RTI Data Distribution Service will create a receive thread for every unique port number that it encounters (on a per transport basis).
A sequence of unicast communication settings.
An empty sequence means that applicable defaults specified by elsewhere (e.g. DDS_DomainParticipantQos::default_unicast) should be used.
The RTPS wire protocol currently limits the maximum number of unicast locators to four.
[default] Empty sequence.
