C++ (Cpp) Future::has_slave_id примеры использования

Пример #1

Файл: scheduler_driver_tests.cpp Проект: ChrisPaprocki/mesos

// in an acknowledgement message by dropping it. The driver will
// log an error in this case (but we don't test for that). We
// generate a status with no slave id by performing reconciliation.
