Detailed Description

Entity:
com.rti.dds.subscription.DataReader com.rti.dds.publication.DataWriter
Properties:
RxO = N/A;

Usage

The DATA_TAG QoS policy can be used to associate a set of tags in the form of (name, value) pairs with a com.rti.dds.subscription.DataReader or com.rti.dds.publication.DataWriter. This is similar to the com.rti.dds.infrastructure.PropertyQosPolicy, except for the following differences:

  • Data tags are always propagated. You cannot select whether or not a particular pair should be propagated.
  • Connext passes data tags to the Access Control Security Plugin, which may use them to decide whether to allow or deny the corresponding entities.

There are helper functions to facilitate working with data tags. See the DATA_TAG page.
