When a microservice instance is removed, this message notifies the microservice registry. The registry will then delete the reference to this instance as well.

Usage

Example of use (after generating of the class CRecordRemoveMicroServiceInstance): 

private void sendRemoveMicroService(@NotNull final CTargetAddress aAddressOfMicroserviceRegistry,
                                    @NotNull final IId aMicroserviceId,
                                    @NotNull final IId aMicroserviceInstanceId) throws CException
{
    final CEnvelope env = CEnvelope.forSingleTarget(aAddressOfMicroserviceRegistry);
    final CRecord rec = CRecordRemoveMicroServiceInstance.create();
    CRecordRemoveMicroServiceInstance.setMicroServiceId(rec,
                                                        aMicroserviceId);
    CRecordRemoveMicroServiceInstance.setMicroServiceInstanceId(rec,
                                                                aMicroserviceInstanceId);
    sendRequest(env,
                rec);
}

Record Usage

In nyssr.net, we typically don't exchange interfaces between projects. Instead, we use platform-independent Records to describe message formats.

One or more descriptions of these Records are stored in the JSON or XML format as record.json or record.xml within a directory. The Record Generator, an included Swing tool, generates helper classes from these files. These classes can then be used to type-safely write or read messages.
