Concurrent collaboration model "producer/consumer model"—>management method
-
Producer: The module responsible for producing data (may be methods, objects, threads, processes);
-
Consumer: the module responsible for processing data (may be methods, objects, threads, processes);
-
Buffer: Consumers cannot directly use the producer's data, there is a "buffer" between them
-
The producer puts the produced data into the buffer, and the consumer takes out the data from the buffer
