Lab 00: "As generated" code

• This lab contains unmodified type-support code and an example application that was generated with the following command:

Linux and MacOS

$NDDSHOME/bin/rtiddsgen -language c# -example net6 ./example.idl

Windows

%NDDSHOME%\bin\rtiddsgen.bat -language c# -example net6 -ppDisable example.idl

• Note that in the *.csproj file, the line:

<PackageReference Include="System.CommandLine" Version="2.0.0-*" /> 

was changed to:

<PackageReference Include="System.CommandLine" Version="2.0.0-beta1.21308.1" />

• see https://community.rti.com/kb/how-fix-error-cs0234-type-or-namespace-name-commandhandler-does-not-exist-connext-dds-c-examples for more detail regarding why this is needed.

Lab 01. Add some "dummy data"

• Let's make the following changes to the publisher. In examplePublisher.cs make the following changes in the writing loop:
  • Set sample.id to a constant number
  • Give dynamic values to sample.point.[x|y|z]

Lab 02. Deadline QoS

• In USER_QOS_PROFILES.xml, add a deadline section to the DataReader Qos.
  • Observe that no data flows; this is because we also need to have the DataWriter offer a deadline
    • fix the issue in XML
• Use Admin Console to observe that a QoS mismatch exists
• Use handlers in exampleSubscriber.cs to programmatically learn about
  • any QoS mismatch
  • any deadline missed events
  • NOTE The waitset must be configured before the handers-- this is due to known issue CORE-11125

Lab 03. Add constants to IDL, use them in the source

• We can declare const strings in the IDL so that string literals do not have to be manually entered in source. Let's do that for:
  • The Topic name
  • The QoS library and profile
• The type support code now needs to be regenerated, but be careful not to overwrite the example files

%NDDSHOME%\bin\rtiddsgen.bat -language c# -update typefiles -ppDisable example.idl

• Update examplePublisher.cs and exampleSubscriber.cs to use these constants.
