清单3中的示例显示可以如何将此操作符与 ! $ 运算符组合使用。
The example in Listing 3 shows how you can use this operator in combination with the !$ operator.
操作可以是一个关系运算符,或者系统或用户定义的函数,也可以是一个sql操作符,例如GROUPBY、ORDER BY等。
An operation can be a relational operator, a system - or user-defined function, or an SQL operator, such as GROUP BY, ORDER BY, and so on.
尽管和[]在运算期间使用相同的测试操作符,但是它们使用不同的逻辑操作符。
Although and [] use the same test operators during evaluation, they use different logical operators.
单目操作符(unaryoperator)是通过在关键字operator后跟单目运算符符号来命名的。
A unary operator is named by using the key word operator followed by the unary operator symbol.
在OmniFind 中,与该概念关系最密切的映射是-符号,其在大多数情况下是可用于搜索的 “异”运算操作符,但是不会生成它自己的结果。
In OmniFind, the closest mapping to this concept is the - symbol, which is more of an exclusion operator that can be applied to the search, but will not generate results of its own.
在我们的四则运算表达式里面我们可以利用继承实行从一元到二元操作符的表示,但它实质上会干扰测试。
In our arithmetic expressions we could have used inheritance to get from a unary to a binary operator node, but that would substantially violate the test.
因此减号操作符的运算结果类型依赖于操作数被提升之后的类型。
The result of the unary - operator is the negative of its (promoted) operand. The integer promotions are performed on the operand, and the result has the promoted type.
