Detailed Description

<<interface>> Conditions specifically dedicated to read operations and attached to one com.rti.dds.subscription.DataReader.

com.rti.dds.subscription.ReadCondition objects allow an application to specify the data samples it is interested in (by specifying the desired sample_states, view_states as well as instance_states in com.rti.ndds.example.FooDataReader.read and com.rti.ndds.example.FooDataReader.take variants.

This allows RTI Connext to enable the condition only when suitable information is available. They are to be used in conjunction with a WaitSet as normal conditions.

More than one com.rti.dds.subscription.ReadCondition may be attached to the same com.rti.dds.subscription.DataReader.
