Detailed Description

<<interface>> Conditions specifically dedicated to read operations and attached to one DDS::DataReader.

DDS::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 DDS::TypedDataReader::read and DDS::TypedDataReader::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 DDS::ReadCondition may be attached to the same DDS::DataReader.
