您要查找的是不是:
- Adds a new field to the dynamic type. 向动态类型中添加新字段。
- It also enforces dynamic type safety by doing runtime checks. 运行环境检查时,同样也是安全地执行动态类型。
- The dynamic type of an rvalue expression is its static type. 一个右值表达式的动态类型,就是它的静态类型。
- Examples of languages that use dynamic typing include PHP, Lisp, Perl, Python, Ruby, and Smalltalk. 使用动态类型的程序语言在运行时检查数据类型(又称“懒加载”),这与编译时相对。
- Returns a value that indicates whether the current dynamic type has been created. 返回一个值,该值指示是否已创建当前动态类型。
- While this solution works, it requires a dynamic type check at run-time, which adds overhead. 当以上解决方案运行时,加在上面的代码要求进行一个运行时的动态类型检查。
- Some programs need to directly interrogate the dynamic type of an object at run time. 一些程序需要在运行时直接询问对象的动态类型。
- The dynamic type of an object (as opposed to a reference or pointer) is always the same as the static type of the object. 对象的动态类型总是与静态类型相同,这一点与引用或指针相反。
- Constructors are run before the object is fully constructed.While the constructor is running, the object's dynamic type is not complete. 构造函数是在对象完全构造之前运行的,在构造函数运行的时候,对象的动态类型还不完整。
- Smalltalk support a dynamic type system (only) and that view translated into C++ leads to extensive unsafe and ugly casting. Smalltalk(只)支援动态型别系统,而这些观点转移至C++将会导致广泛的安全性问题与丑陋的型态转换。
- Describes the ways types can be created, the attributes that can be used, and limitations of dynamic type creation. 介绍可创建类型的方式、可使用的属性以及对动态类型创建的限制。
- Erlang is a general-purpose concurrent programming language and runtime system.The sequential subset of Erlang is a functional language with strict evaluation single assignment and dynamic typing. Erlang拥有许多近似Pure Functional Language的特性,对于习惯于物件导向、指令式编程的Programmer来说,应该算是相当奇怪的语言。
- The following code sample demonstrates the use of DefineConstructor to set a constructor's particular signature and attributes on a dynamic type and return a corresponding ConstructorBuilder for IL population. 下面的代码示例演示了如何使用DefineConstructor设置构造函数的特殊签名和动态类型的属性并为IL填充返回相应的ConstructorBuilder。
- The IsConstructor property returns false for a ConstructorBuilder object in a dynamic type, unless the MethodAttributes.RTSpecialName flag was included in the attributes parameter when the constructor was defined. 对于动态类型的ConstructorBuilder对象;IsConstructor属性返回false;除非定义构造函数时;attributes参数中包括MethodAttributes.;RTSpecialName标志。
- The fact that the static and dynamic types of references and pointers can differ is the cornerstone of how C++ supports polymorphism. 引用和指针的静态类型与动态类型可以不同,这是C++用以支持多态性的基石。
- If a call omits an argument that has a default value, then the value that is used is the one defined by the type through which the function is called, irrespective of the object's dynamic type. 如果一个调用省略了具有默认值的实参,则所用的值由调用该函数的类型定义,与对象的动态类型无关。
- We are looking for dynamic persons to be salesmen. 我们正在寻找充满活力的销售人员。
- gas dynamic type of chemical laser 气动式化学激光器
- VBScript and Python are dynamically typed, because they figure out what type a variable is when you first assign it a value. 静态语言和动态语言实际上应该翻译成静态类型语言和动态类型语言,分别是指“变量”类型在编译时指定的语言和执行时指定的语言。
- Dynamic languages are defined as high-level, dynamically typed, and open source, developed by a grassroots community rather than a corporation or consortium. 有一句话定义了动态开源语言的定义:高级语言与开放源代码,由一个民间的社区而非一家公司或国际财团开发的。
