The Bitwise Exclusive OR Operator and its Application to Strategy for Playing

按位异或及其在求解游戏策略问题中的应用

The bitwise AND operator (&) produces a one in the output bit if both input bits are one;

若两个输入位都是1，则按位AND运算符（&）在输出位里生成一个1；

Just a side note, there is also a bitwise operator you can use if you want to trace everything except a certain component.

另外提醒一点，如果想跟踪除了某个组件之外的所有组件，还可以使用另一个位操作符。

The bitwise operator for all except is (~).

这个位操作符就是（~）。

But if you need more detailed tracing in certain JDBC universal driver components, then the bitwise operator will enable you to do this.

但是如果需要更详细地规定跟踪某些JDBC通用驱动程序组件，那么可以通过位操作符来做到这一点。

If you want to trace more than one specific traceLevel property, then you can use bitwise operator (') to separate the different properties.

如果想跟踪不止一个特定的traceLevel属性，那么可以使用位操作符（）来分隔不同的属性。
