TypeObject and TypeCode

TypeObject and TypeCode support in RTI Connext DDS During the matching process , RTI Connext DDS compares the structure of the topic types provided by the DataWriters and DataReaders to determine if they can communicate. To do so, the TypeObject or TypeCode is needed. If the TypeObject or TypeCode ...

Communicating DDS Entities with different type bounds

By default, a DataWriter of an unbounded type won’t be able to communicate with a DataReader of a bounded type. DDS includes the max size of a bounded type as part of the data type information (known as TypeCode or TypeObject). Since the data type information is used during the Discovery phase, if ...

What is the purpose of the different GUID and Sequence_Number fields in DDS_SampleInfo?

The DDS_SampleInfo associated with each sample contains the fields original_publication_virtual_guid and original_publication_virtual_sequence_number . This pair forms the SampleIdentity which uniquely identifies each individual sample. When a DataWriter uses write_w_params (), it can explicitly ...

Implications to set publish_with_original_info to true in Routing Service configuration

The default value for publish_with_original_info is false. When this property is set to false RTI Routing service will change the metadata fields Writer GUID and Sequence Number in every sample. As a consequence, the applications can not know the original source of the sample, that is the ID of the ...

Why can't more than 5 DomainParticipants communicate within in the same machine?

If you have more than 5 DomainParticipants in the same machine, you may notice that your applications are not able to communicate with Participant number 6 and following ones. This is because by default we discover up to 5 DomainParticipants in one location. This behavior is controlled by the Peer ...
