当在另一个标记的属性中调用方法时，大括号表示法(正式名称为表达式语言或el语法)更合适。
The curly-brace notation (formally known as Expression Language or EL syntax) is better suited for times when the method call is embedded in another tag's attributes.
只有在赋值和调用时，表达式才应被当作一条单独的语句。
The only expressions that should be used as statements are assignments and invocations.
OQL查询同样可以调用对象的方法，将正则表达式作为查询的一部分，并使用内置查询工具。
OQL queries can also invoke methods on the objects themselves, use regular expressions as part of the query, and use built-in query tools.
也可以建立布尔表达式以调用方法。
You can also set up the Boolean expression to call a method.
在组件框架中，UI事件或解析的值绑定表达式直接导致方法调用。
In a component framework, invocations are a direct result of either UI events or resolved value-binding expressions.
表达式由数据结构、绑定的变量（即具有值的变量）、数学操作符和函数调用组成。
The expression is composed of data structures, bound variables (that is, those with a value), mathematical operations and function calls.
例如，通过合并其两个操作数的枚举使在联合表达式上调用enumerate可行。
Calling enumerate on a union expression, for example, works by merging the enumerations of its two operands.
要创建Pattern，必须调用它的compile，同时传递一个正则表达式作为参数。
To create a Pattern, you must call its compile , passing a regular expression as an argument.
该表达式是对lazy - seq - fibo的一个递归调用，不过这次，它调用的是有两个参数的情况，并向其传递0和1。
That expression is a recursive call to lazy-seq-fibo, but this time, it is calling the two argument case, passing in 0 and 1 to it.
XQuerywhere子句可以包含任意复杂的嵌套表达式，甚至可以包含函数调用。
The XQuery where clause can consist of nested expressions of arbitrary complexity that can even include function calls.
然后，当调用process时，它在从CAS收到的文档文本中寻找与正则表达式匹配的地方。
Then, when process is called, it finds matches of the regular expression in the document text that it gets from the CAS.
如果表达式不是常量，就调用另一个宏函数把值向上取整到2的幂。
Otherwise, if the expression is not a constant, another macro function is called to round up the value to a power of two.
当框架调用initialize时，NameReferenceAnnotator从描述符以字符串形式读取正则表达式并编译它。
When initialize is called by the framework, the NameReferenceAnnotator reads the regular expression as a string from its descriptor and compiles it.
该查询的有趣部分在XMLQuery函数调用中包含的表达式中。
The interesting portion of this query is contained in the expression included in the XMLQuery function call.
lambda的其余参数是调用函数时的计算表达式。
The remaining arguments to lambda are the expressions to be evaluated when the function is called.
首先，为了对类型参数构造合法的new表达式（如 newT() ），必须确保我们调用的构造函数对于 T 的每个实例化都有效。
First off, in order to form a legal new expression on a type parameter, such as new T(), it's necessary to make sure that we're calling a constructor that is valid for every instantiation of T.
路径表达式的第一步调用db 2 - fn：xmlcolumn函数从clients表的contactinfo列获得一个xml文档的列表。
The first step of the path expression calls the db2-fn: xmlcolumn function to obtain a list of XML documents from the CONTACTINFO column of the CLIENTS table.
在这种情况下，这个表达式调用内置的strftime()函数，这个函数会返回一个标准时间戳字符串：“FriOct23 14:51:01 2009”。
In this case, that expression is a call to the built-in strftime() function, which returns a standard timestamp string of the form: "Fri Oct 23 14:51:01 2009".
在一个字符串上调用。r会把它变成一个正则表达式；我们是用了原始(三重引号)字符串来避免诸多双重转义的反斜杠。
Calling.r on a string turns it into a regular expression; we use raw (triple-quoted) strings here to avoid having to double-escape backslashes.
既然Duby可以方便地将不明类型或动态类型的表达式看做是需要动态调用的，那么没理由不把Surinx吸收为Duby的特性之一。
And since Duby could easily treat untyped or dynamic-typed expressions as requiring dynamic invocation, there's no reason Surinx shouldn't just be assimilated as a feature of Duby.
闭包是函数字面量(unction literal)——是包含了一个递延计算的表达式，该计算可被当成值对待，在晚些时候再调用。
Closures are function literals - expressions that embody a deferred computation that can be treated as a value and invoked later.
清单5中第二行调用对rope进行修饰，优化正则表达式匹配。
The call on the second line in Listing 5 decorates the rope to optimize regular-expression matching.
在diamond表达式出现在方法调用上下文时会有轻微的不同。
The story is slightly different when the diamond expression appears in a method-invocation context. Consider a Box that appears as an argument to the m() method
在这个宏执行时，它按照以下形式将my - if表达式与模板进行匹配(换句话说，将宏调用与宏定义模式进行匹配)。
When this macro executes, it will match the my-if expression up to the template like this (in other words, matching a macro invocation to a macro definition pattern).
可以调用这个shell，以交互模式（在这种模式中，可以输入要计算的表达式或要执行的代码）或批处理模式运行它。
The shell can be invoked to run in either interactive mode (in which case you can enter expressions to be evaluated or blocks of code to be executed) or batch mode.
