<<interface>> Conditions specifically dedicated to read operations and attached to one DDSDataReader.
DDSReadCondition 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 FooDataReader::read and 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 DDSReadCondition may be attached to the same DDSDataReader.

Returns the DDSDataReader associated with the DDSReadCondition.
There is exactly one DDSDataReader assicated with each DDSReadCondition.
