例句

根据特定上下文的要求，可以用不同的父类实例化mixin。

Mixins are allowed to have parameters, just like components.

混合允许有参数，就像组件一样。

By incorporating mixins using generic types, we are able to work around many of the key limitations of other formulations of mixins.

通过使用泛型类型合并mixin，我们能解决其它mixin公式的许多关键限制。

The reason: both mixins and generic classes can be thought of as functions mapping existing classes to new classes.

原因是：mixin和泛型类都能被认为是将现有类映射到新类的函数。

Nevertheless, it's a very unfortunate restriction because it limits the set of classes eligible to be turned into mixins.

然而它仍是一个非常遗憾的约束，因为它限制了适合于转换成mixin的类集合。

But it is appealing, almost seductive, to incorporate mixins as part of a generic type system.

但是合并mixin以作为泛型类型系统的一部分很吸引人，几乎可以说魅力无穷。

Mixins can be viewed as functions mapping existing classes to new subclasses.

mixin可被视为将现有类映射成新子类的函数。

The Mixins annotation allows a list of mixing names to be specified.

Mixins标注允许指定一个混合名字的列表。

Mixins: allow to extract common groups of properties, name them and then include them in selectors.

混合类型：允许开发者抽象出性质的共同点，然后命名并且加入到选择器中。

When mixins are formulated as generic classes, the problem of accidental overrides is particularly nasty.

当mixin被明确表述为泛型类时，意外覆盖的问题特别讨厌。

With mixins formulated as generic classes, we always have a handle on the parent class, the type parameter that the class extends.

将mixin明确表述为泛型类，我们就始终有父类的句柄，它是该类继承的类型参数。

However, there are other significant difficulties with formulating mixins as generic types.

但是，将mixin明确表述为泛型类型时有其它一些明显的困难。

This can mean generating new objects from a runtime definition or based on mixins of existing types or objects.

这可能意味着产生新的物体从一个运行的基础上定义或mixins现有类型或对象。

Mixins are classes that are parameterized by their parent class.

mixin是那些由它们的父类参数化的类。

Although mixins are simply a design pattern in these languages, there's no reason why they can't be supported at the language level.

尽管mixin只是这些语言中的一种设计模式，但在语言级别上支持它们应该是毫无问题的。

Static members are associated with instantiations of mixins; there are no "shared" static members of mixins.

静态成员与mixin的实例化相关联；没有“可共享”的mixin静态成员。

In the case of mixins as generic types, we can apply the same solution.

在mixin作为泛型类型的情况中，我们可以应用同样的解决方案。
