BasicRegister¶
Base class which implements the parts shared by all registers, such as
initialization and the handling of the final XOR value. It leaves the actual
per byte update to its subclasses, Register and
TableBasedRegister.
Bases: AbstractRegister
Implements the common crc algorithm, assuming a user of this base class will provide an overwrite for the _process_byte method.
