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.
