Enumerator
AUTOMATIC_LIVELINESS_QOS	[default] The infrastructure will automatically signal liveliness for the DDS::DataWriter (s) at least as often as required by the DDS::DataWriter (S) lease_duration. A DDS::DataWriter with this setting does not need to take any specific action in order to be considered 'alive.' The DDS::DataWriter is only 'not alive' when the participant to which it belongs terminates (gracefully or not), or when there is a network problem that prevents the current participant from contacting that remote participant.
MANUAL_BY_PARTICIPANT_LIVELINESS_QOS	RTI Connext will assume that as long as at least one DDS::DataWriter belonging to the DDS::DomainParticipant (or the DDS::DomainParticipant itself) has asserted its liveliness, then the other DataWriters belonging to that same DDS::DomainParticipant are also alive. The user application takes responsibility to signal liveliness to RTI Connext either by calling DDS::DomainParticipant::assert_liveliness, or by calling DDS::DataWriter::assert_liveliness, or DDS::TypedDataWriter::write on any DDS::DataWriter belonging to the DDS::DomainParticipant.
MANUAL_BY_TOPIC_LIVELINESS_QOS	RTI Connext will only assume liveliness of the DDS::DataWriter if the application has asserted liveliness of that DDS::DataWriter itself. The user application takes responsibility to signal liveliness to RTI Connext using the DDS::DataWriter::assert_liveliness method, or by writing some data.
