◆ instance_id
| GUID_t DDS::ServiceRequest::instance_id |
Each ServiceRequest is keyed on the instance_id.
The instance_id provides a way for users to differentiate between different requests coming from the same service.
◆ request_body
| ByteSeq ^ DDS::ServiceRequest::request_body |
Service-specific information.
Each service uses the request_body field to send information specific to that service in the form of an opaque sequence of bytes. Each service provides a helper function that will deserialize the information from the request body.
