使用反射来传递和修改图元而不使用数组 [英] Using reflection to pass and modify a primitive without using array
问题描述
在imgui 端口上工作时，我一直被用作原始数组来模拟c ++指针/地址通过.
Working on a imgui port, I've been always used primitive arrays to simulate c++ pointers/addresses pass.
例如:
checkbox("Anti-aliased lines", bool.apply { set(0, style.antiAliasedLines) })
style.antiAliasedLines = bool[0]
其中bool: BooleanArray
我只是探讨了直接传递字段的可能性，例如c ++:
I just explored the possibility to directly pass the field instead, sort of c++:
ImGui::Checkbox("Anti-aliased lines", &style.AntiAliasedLines);
kotlin:
checkbox("Anti-aliased lines", style::antiAliasedLines })
我只需要在checkbox()上容纳一个相应的KMutableProperty0<Boolean>，我还仔细检查了是否可以在同一函数中设置该字段:有一个get(): Boolean和set(Boolean)
I just needed to accomodate a corresponding KMutableProperty0<Boolean> on checkbox(), and I also double checked to have the possibility to set that field within the same function: there is a get(): Boolean and a set(Boolean)
我担心的是:
-
与Java配合使用会很好吗?
does this play nice with java?
如果我沿着这条路线走，我应该注意哪些禁忌症?诸如表演之类的?
are there any contraindications I should be aware of, if I go down this route? Such as performances or whatever?
因为我有一种感觉，因为这种方法有点笨拙和肮脏
Because I got the feeling that since this approach is somehow hacky and dirty
推荐答案

一件行不通的事是引用Kotlin用来表示Java getter和setter的合成属性，例如getFoo + setFoo→foo(并且不能使用绑定的可调用引用bar::foo).目前尚不支持.
One thing that won't work is referencing synthetic properties that Kotlin uses to represent Java getters and setters, e.g. getFoo + setFoo → foo (and you cannot use a bound callable reference bar::foo). This is not supported for now.
您可以尝试通过自定义KMutableProperty0实现来解决该问题，该实现接受对Bar::getFoo，Bar::setFoo和bar的未绑定可调用引用，并在获取和设置其值的意义上充当属性引用. /p>
You can try to workaround that by a custom KMutableProperty0 implementation that accepts unbound callable references to Bar::getFoo, Bar::setFoo and bar and acts as a property reference in the sense of getting and setting its value.

绑定的可调用引用拥有对接收方的引用，因此style::antiAliasedLines将使style与GC隔离，并且您必须注意存储哪些可调用引用.
A bound callable reference holds a reference to the receiver, so style::antiAliasedLines will keep style from GC, and you have to be careful about which callable references you store.
