Interface SampleSelectCallback

public interface SampleSelectCallback

Allows callers to hook into the sample selection and processing calls without exposing implementation details. This was originally written to give the caller to limit the number of concurrent calls to ResultProcessor#process, while allowing for a greater number of threads to retrieve the samples.
