可以被覆盖/实现的Ruby操作符列表 [英] list of ruby operators that can be overridden/implemented

问题描述

在所有可以替换的红宝石运算符的任何地方都有列表吗? (不是那些不能的！)

Is there a list anywhere of all ruby operators that can be overridden? (Not the ones that can't!)

推荐答案

以下是表格Ruby运算符.

属于方法且可重载的是:

The ones that are methods and overloadable are:

[ ] [ ]=    Element reference, element set
**  Exponentiation
! ~ + -     Not, complement, unary plus and minus (method names for the last two are +@ and -@)
* / %   Multiply, divide, and modulo
+ -     Plus and minus
>> <<   Right and left shift
&   Bitwise `and'
^ |     Bitwise exclusive `or' and regular `or'
<= < > >=   Comparison operators
<=> == === != =~ !~     Equality and pattern match operators (!= and !~ may not be defined as methods)

该表来自2001年的Pickaxe书籍，但这与Ruby 1.9 Pickaxe的书籍相同.没有理由相信这组中缀运算符会发生变化.

The table was from the 2001 Pickaxe book, but that's the same table as in the Ruby 1.9 Pickaxe book -- no reason to believe that this set of infix operators will ever change.
