I suppose that in this case you do not need an interface at all. They represent
an abstract service that other components depend upon.
In the POLL case, you define a concrete service that doesn't realize an abstract
interface in contrast to a serial driver, for instance, which provides abstract
read/write/... operations to clients but requires a concrete, hardware specific
implementation that realizes the serial interface by defining these operations.
