说明:比较操作符&1操作数不兼容。
还应注意,xsl:if中的“小于”和“大于或等于”比较操作符也需要转义,以遵从xml规则。
Note also that the comparison operators for "less than" and "greater or equal to" inside the XSL: if statement are also escaped to comply with XML rules.
到目前为止,要想使用定制的比较函数,标准的做法是定义自己的函数对象,然后适当地定义操作符。
So far, to use custom comparison functions, the standard practice has been to define your own function object and then define the operator appropriately.
上面规则的使用都比较可疑,因为他们都可以通过不使用任何替换操作符来重写.
The use of the above rules is questionable, as they all could be rewritten without using any substitution operators.
比较图4和图5中的访问计划,会发现对于EISCAN操作符,查询使用了一个扩展索引。
Comparing the access plans in Figure 4 and Figure 5 shows again with the EISCAN operator that an extended index is used by the query.
在1.5.2的黄金时代,无论比较什么对象,不等操作符总会返回一个结果。
Back in that golden age of 1.5.2, you knew the inequality operators would return a result regardless of which objects were compared.
在清单1的第一个示例中,- gt操作符对两个字符值之间执行算术比较。
In the first example in Listing 1, the -gt operator performs an arithmetic comparison between two literal values.
Shell并没有提供大量的算术操作符,但是已经足以完成大多数编程任务,包括移位、求余和比较。
The shell doesn't have a large collection of arithmetic operators, but it's sufficient for most programming tasks, including bitwise shifts, remainders, and comparisons.
eq操作符只能用于比较原子值。
这个大于的操作符的时候,是到类的定义里去识别,大于是一个比较的方法,那么让我在这里说仔细一点吧。
When I try and evaluate that expression of greater than, is going to go into the class to say greater than is a comp method.
与前一组测试操作符一样,比较测试操作符是执行错误检查或根据另一个值测试值的简便方法。
Like the previous set of test operators, comparison test operators are a handy way to perform error checking or to test values against another value.
另一组测试操作符称为比较测试操作符。
Another set of test operators is called comparison test operators.
可以按照与其他操作符相同的格式使用比较测试操作符。
You use the same format on comparison test operators as other operators.
除了上面的一元测试以外,你也可以通过一对操作符来对两个文件进行比较,如表2。
In addition to the unary tests above, you can compare two files with the binary operators shown in Table 2.
这将会是个默认的或者说是,通用的来比较对象是否相同的方法,好,在每个例子中,这些事情正在做的,就是,一些与操作符重载有关的东西。
OK, in each case, what these things are doing, is they're doing, what sometimes gets referred to as operator overloading.
所以你唯一改变的是添加另一个操作符和(可能)循环减慢一点(拖欠的比较是慢于操作符)。
So the only thing you changed is adding another operator and (possibly) slowing down loop a little (AFAIR comparison is slower than bit operators).
