减少样式表中变量引用的数量。
Reduce the number of variable references in your stylesheets.
同时,也可以用多个变量引用同一个对象。
And you can have multiple variables referencing the same object.

但是lambdas的真正优势是,在您忙着创建函数时,不需要变量引用。
But the real advantage to lambdas is when you create functions on the fly and no variable reference is required. For example.
比方说,表达式中的变量引用将导致错误,即使元素确实位于变量有效的模板中。
For example, a variable reference in the expression results in an error even though the element is positioned in a template where the variable is in scope. Some key differences are.
只需将对闭包的变量引用传递到reflectionmethod类的构造函数中。
We simply pass the variable reference to the closure into the constructor of the ReflectionMethod class.
如果任意一个函数参数或者局部变量引用了客户端对象,你就导致了内容泄漏。
If any of those function arguments or local variables refer to a client-side object, you may be creating a memory leak.
因此,流开发人员不应该使用变量引用表达式映射到名称列可能为 NULL 的路由决策。
Therefore flow developers should not use routing decisions in which variable reference expressions map onto name columns whose values may be NULL.
对象变量引用本质上就是一种动态存储方法,在此基础上便能实现链式动态存储。
In substance, citing of object variable is a method of dynamic storage, which dynamic storage based on link can be implemented.
注意我是如何通过application变量引用ServletContext的实例的。
See how I was able to reference the instance of ServletContext via the application variable?
如果检索到的列值为SQLNULL,那么不会给此类值分配任何XPath变量引用表达式。
In the case where a retrieved column has a value of SQL NULL, then no XPath variable reference expression is assigned to such a value.
同样,可能读到一个引用变量的最新值,但读取到这个引用变量引用的对象的字段的过期值。
Similarly, it is possible to read a fresh, updated value of a reference variable, but a stale value of one of the fields of the object now being referenced.
若要简化维护,可以更新数据库项目中的对象,以使这些对象使用变量引用其他数据库中的对象。
To simplify maintenance, you can update the objects in your database project so that they use the variables to refer to objects in other databases.
如果没有在模板中声明通道参数,而模板正好又没使用它的话,就不用担心和模板中的变量引用发生名称冲突。
If you don't declare a tunnel parameter because it is not used in that template, then you don't have to worry about its name clashing with any variable reference in that template.
要注意,使用 $treeFarm上下文属性引用的方法和前面分析的 $treeList变量引用一致。
Note that the syntax of using the $treeFarm context attribute reference is identical to the $treeList variable reference examined earlier.
如果变量引用的对象在另一个应用程序中,此测试无法确定该应用程序是已经终止对象还是只是使对象无效。
If the object your variable refers to is in another application, this test cannot determine whether that application has terminated or just invalidated the object.
采用引用的方式赋值到模板中,而不是在模板中创建一个数值的副本。引用的概念可以查看PHP手册的变量引用部分。
This is used to assign values to the templates by reference instead of making a copy. See the PHP manual on variable referencing for an explanation.
它只保存一段数据:一个字符串、一个数字、未定义的值以及对另一个变量的引用。
They hold only one piece of data: a string, a number, the undefined value, a reference to another variable.
请注意,这里有一个将被选中表达式所有出现的地方都替换成新变量的引用的选项。
Notice that there is an option to replace all occurrences of the selected expression with references to the new variable.
在这一模型中,您创建的所有变量都将引用在总的类层次结构中创建的对象。
In this model, any variable you create references an object that has been created from the overall class hierarchy.
谨慎引用变量。
注意,稍后您也可以使用闭包和引用变量。
Note that you can use closures and reference variables later too.
消息能够包含对备忘单变量的引用以便显示它们的内容。
The message can contain references to cheat sheet variables in order to display their content.
目前不支持访问数组、实例变量和对象引用。
Accessing arrays, instance variables, and object references are not supported as of now.
相反的,动态类型的语言则是根据变量所引用的值来绑定类型,这意味着变量的类型可以随着它引用的值改变而改变。
In contrast dynamically typed languages bind the type to the actual value referenced by a variable, meaning that the type of a variable can change along with the value it references.
这些变量可以在包主体中引用。
通过在CLASSPATH环境变量中引用该位置,就可以使用那个文件。
You can take advantage of that by simply referencing it in the CLASSPATH environment variable.
然后仅从原始位置复制这些单元,并带上其引用的变量。
Only those units are then copied from the original source with the variables they refer to.
然后表达式中对变量的引用可以静态绑定到本地堆栈框架或一列全局变量的特定槽上。
References to variables within an expression can then be statically bound to a particular slot in either the local stack frame or the list of global variables.
参数名(引用变量)应该使用唯一的名称。
Parameter names (reference variables) should have unique names.
