Bitmasking involves both the bitwise logical operators and the bitwise shift operators that you’ve read about. You can find bitmasks in a lot of different contexts. For example, the subnet mask in IP addressing is actually a bitmask that helps you extract the network address. Pixel channels,...

2) A small, somewhat quibbling thought, for C++ users this would seem like an appropriate place to use an iostreams style bit shift operator overload... perhaps less confusing to leave the code as is, but unlike the addition operator, the bitshift operator makes it visually clearer (for c...

Bitshift Composition 位移组合结构 传统上,使用set_upstream()和set_downstream()方法设置operators之间的依赖关系。 在Airflow 1.8中,这可以通过Python bitshift操作符'>>'和'<<'来完成。 例如,以下四个语句在功能上都是等效的: op1 >> op2op1.set_downstream(op2)op2 << op1op2.set_upstream(op1) ...
