Request-Reply Examples

DDS Types

RTI Connext uses DDS data types for sending and receiving requests and replies. Valid types are those generated by the rtiddsgen code generator, the DDS built-in types, and DynamicData. Refer to the User's Manual and the following links for more information:

Set up

Requester: sending requests and receiving replies

Replier: receiving requests and sending replies

Error handling

Requester Creation

Creating a Requester with optional parameters

Basic Requester example

Taking loaned samples

Taking samples by copy

Correlating requests and replies

Basic Requester example using SampleRef

This example is similar to Basic Requester example except it uses a SampleRef instance instead of a Sample instance.

Creating a Replier

Basic Replier example

SimpleReplier example

Error handling example

Configuring Request-Reply QoS profiles

If you do not specify your own QoS parameters (in connext::RequesterParams and connext::ReplierParams), a connext::Requester and connext::Replier are created using a default configuration. That configuration is equivalent to the one in the following QoS profile called "default":

You can use the profile called "RequesterExampleProfile", which modifies some parameters from the default. The example Creating a Requester with optional parameters shows how to create a connext::Requester using this profile.
