Member Data Documentation
◆ NO_RECOVER_INSTANCE_STATE_CONSISTENCY
|
static |
Instance state is not restored on a DataReader after reconnecting with a DataWriter until the DataWriter sends a new sample.
When DataReaders rediscover DataWriters, they will not request updated instance state data. DataWriters always provide instance state data alongside each sample update regardless of this setting.
◆ RECOVER_INSTANCE_STATE_CONSISTENCY
|
static |
Instance state is restored on the DataReader after it reconnects with a DataWriter that has regained liveliness, even before the DataWriter sends a new sample.
When DataReaders rediscover DataWriters, they will request updated instance state data. DataWriters will respond to requests for updated instance state data and publish updates on a builtin channel. DataWriters still provide instance state data alongside each sample update regardless of this setting.
The following limitation applies to using RECOVER_INSTANCE_STATE_CONSISTENCY: If the com.rti.dds.infrastructure.DestinationOrderQosPolicyKind is set to com.rti.dds.infrastructure.DestinationOrderQosPolicyKind.DestinationOrderQosPolicyKind.BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS, RECOVER_INSTANCE_STATE_CONSISTENCY can only be used if scope is set to com.rti.dds.infrastructure.DestinationOrderQosPolicyScopeKind.DestinationOrderQosPolicyScopeKind.INSTANCE_SCOPE_DESTINATIONORDER_QOS (the default).
