如何从构造函数中调用方法F＃ [英] How to invoke methods from constructor in F#

问题描述

我知道这个问题，但asker似乎内容与另一个答案的答案问题（如何重载构造函数）

I'm aware of this question, but the asker seems to have been content with an answer to another question (how to overload the constructor)

我有一个类作为一个可变类的高级memoizer，所以我可以把它看作是不可变的：

I have a class which kind of acts as an advanced memoizer around a mutable class, so that I can treat it as immutable from outside:

type Wrapper(args) =
    let tool = new MutableTool()
    tool.Init(args)  //<--"Unexpected identifier in definition"

    let lookupTable = //create lookup using tool here
    member this.Lookup(s) = //callers use lookupTable here

我无法弄清楚如何在工具上调用Init方法。我缺少什么？

I can't work out how to invoke the Init method on "tool". What am I missing?

推荐答案

IIRC， do 这里：

type Wrapper(args) =
    let tool = new MutableTool()
    do tool.Init(args)

    let lookupTable = //create lookup using tool here
    member this.Lookup(s) = //callers use lookupTable here

我不知道你最后一行代码是什么意思，所以我把它留在你写的...

I'm not sure what you meant with the last line of code, so I left it as you wrote it...
