C generics and c templates are both language features that provide support for parameterized types C #泛型和c + +模板都是用于提供参数化类型支持的语言功能。
Instantiates a new parameterized type object of the specified class without attempting to call a constructor method 分配新对象,但不尝试调用构造函数方法。
Java 5 extended the java language type system to support parameterized types for classes , methods , and values Java 5扩展了java语言类型系统以支持类、方法和值的参数化类型。
At the syntax level , c generics are a simpler approach to parameterized types without the complexity of c templates 在语法层面上, c #泛型是实现参数化类型的更简单方法,不具有c + +模板的复杂性。
Parameterized types provide important compile - time advantages by enforcing proper type usage and eliminating casts from source code 参数化的类型通过确保使用正确的类型及消除从源代码进行类型转换提供了重要的编译时好处。
In generic classes and methods , one issue that arises is how to assign a default value to a parameterized type t when you do not know the following in advance 在泛型类和泛型方法中产生的一个问题是,在预先未知以下情况时,如何将默认值分配给参数化类型t :
Given a variable t of a parameterized type t , the statement t null is only valid if t is a reference type and t 0 will only work for numeric value types but not for structs 给定参数化类型t的一个变量t ,只有当t为引用类型时,语句t = null才有效;只有当t为数值类型而不是结构时,语句t = 0才能正常使用。
In this article , jibx lead developer dennis sosnoski looks at how to use reflection to dig beneath the surface of parameterized types and reveal the full glory of java 5 application data structures 在本文中, jibx首席开发员dennis sosnoski分析了如何用反射深入参数化类型的内部,并充分展示了java 5应用程序数据结构的优势。
The listing 6 code gets the generic type of that field , checks that the result is of the expected type , and then lists out the raw type and the actual type arguments for the parameterized type 字段的类型信息。清单6中的代码得到这个字段的泛型类型,检查结果是否为所预期的类型,然后列出原始类型和参数化类型的实际类型参数。
