在编程语言中使用任何类型和实现通用列表 [英] Any type and implementing generic list in go programming language
问题描述
我正在尝试一些去编程语言。
我对Go的简单性感到兴奋,但在玩完它之后,我遇到了一些麻烦。
1。我知道 Go 不支持泛型和继承。 有没有什么办法可以实现泛型列表?
我在考虑使用:
类型任何接口{}
但是如何检查if该值为NULL。
我正在寻找一些等价的实现C
struct List {
List * tail;
void * head;或者使用代数数据类型:
$ b b
数据List a = Nil |缺点(列表a)
2。更高级的要求是为为某个特定类型的字段的对象创建一个容器
例如,在 Scala编程语言中,我可以键入:
val列表[Animal {type SuitableFood = Grass}]
获得 List 动物
,它的成员类型为 SuitableFood
,它是 Grass
听起来就像你试图做的是一个链表。
这是一个包含在golang中的例子:
http://golang.org/pkg/container/list/
以下是源代码:
http://golang.org/src/pkg/container/list/list.go
I'm trying a little of go programming language.
I'm a excited about the simplicity of the Go, but after playing with it I met some troubles.
1 . I know that Go doesn't support generics and inheritance. Is there any way to implement generic list?
I thinking about using:
type Any interface { }
but how can I check if the value is NULL.
I'm looking for some equivalent implementation to C
struct List {
List* tail;
void* head;
}
Or using algebraic datatype:
data List a = Nil | Cons a (List a)
2 . More advanced requirement would be to make some container for objects with a field of a particular type?
For example in Scala programming language I can type:
val List[Animal { type SuitableFood = Grass} ]
to get a List
of Animals
, which have a member type SuitableFood
which is Grass
It sound's like what you're trying to make is a linked list.
Here's an example of one included with golang:
http://golang.org/pkg/container/list/
And here's the source code:
http://golang.org/src/pkg/container/list/list.go
