2.4.4. Define Participants and Entities

The Participant view allows you to add Participants, DataReaders, and DataWriters. You have to organize them into Participant Libraries.

2.4.4.1. Adding Participants

To add a new Participant Library to your model, click the button while Participant Libraries is selected or right-click Participant Libraries in the tree and select Add Library:

To add a Participant Library, enter the Library Name and the destination file:

You can then add a Participant to the newly created Library by using the button or by right-clicking on the Participant Library in the tree and selecting Add Participant:

A dialog will guide you to pick a name and select one of the existing domains as the Domain Reference. You can also view and edit the QoS and select a file where the new participant will be stored:

Now you can configure Publications and Subscriptions in the structured view:

Configuring publications and subscriptions

To add a new Publisher, select the button in the Publishers table. You can then select Name, Multiplicity, and QoS Policies in the presented dialog:

Once you click OK, the new Publisher will be available in the Structured view and in the tree on the left:

Now you can add DataWriters to the selected Publisher. Use the button and in the pop-up window, select the topic reference, the name of the DataWriter, Multiplicity, and QoS:

Follow the same logic to add Subscribers and DataReaders in the Subscriptions view.
