为什么需要一些运营商。 例如,比较操作者。
< <= > >= = <>
你们还必须执行补充措施?
< >=
限制你只执行目标
<
如果对它有具体意义,
>=
does
<>说明: 环绕一号工作是把奥索尔迪特归属于不想要的经营者。
操作员在Net(至少为C#和VB)上超负荷工作,故意比C++上载的操作员低灵活性。
One reason that Java went so far as to remove overloading entirely is that too many developers abused overloading to do clever-looking things that confused other developers and broke core assumptions of generic algorithms that expect to be able to, say, reasonably compare two instances of a user type.
虽然“网络”使一些灵活性有所回升,但设计者谨慎行事,只允许某些操作者超负荷工作,其意图是只将其用于其习惯含义。
要求进行对称操作者的比较,是这一意图的明证。
如果你想做更积极的操作者超负荷工作,我鼓励你考虑使用F#,在那里,你可以接触到一个范围更广的象征物,以吸引 operator操作者符号。
或许是因为如果你超负荷经营人一方,你正在执行某些习惯规则,而违约经营人不符合你的规则,从而产生奇怪的行为。
例如,如果你对内乱的定义;是返回(x > 5); (出于某种原因......)和你对内障的相反规则表示过重视;然后是经营者;
4 > 1(根据你的规则),但4 < 1 也为假(根据缺省规则)。
属不合逻辑的Jim。
