- Extend the multipart API to allow sending vectors of messages or helper
thin wrapper FairMQParts. See example in examples/MQ/8-multipart.
- NewMessage() can be used in devices instead of
fTransportFactory->CreateMessage().
Possible arguments remain unchanged (no args, size or data+size).
- Send()/Receive() methods can be used in devices instead of
fChannels.at("chan").at(i).Send()/Receive():
Send(msg, "chan", i = 0), Receive(msg, "chan", i = 0).
- Use the new methods in MQ examples and tests.
- No breaking changes, but FAIRMQ_INTERFACE_VERSION is incremented to 3
to allow to check for new methods.
Example 1: Sampler -> Sink
A simple topology of two devices - Sampler and Sink. Sampler sends data to Sink via the PUSH-PULL pattern.
runExample1Sampler.cxx and runExample1Sink.cxx configure and run the devices in their main function.
The executables take two required command line parameters: --id and --config-json-file. The value of --id should be a unique identifier and the value for --config-json-file a path to a config file. The config file for this example is ex1-sampler-sink.json and it contains configuration for the communication channels of the devices. The mapping between a specific device and the configuration (which can contain multiple devices) is done based on the id.
