[英]How to do an observable function in Mobx?
I have store with a collection which I want to be read only. 我有一个集合,我想要只读。 I wish to do something like but I don't know if Mobx provides a way to create a reactive function. 我希望做一些类似但我不知道Mobx是否提供了一种创建反应函数的方法。
class Store{
private _col:Mobx.Map;
...
@observable public has(id){
return _col.has(id);
}
}
I am on a game architecture with no-trust-the-client in mind. 我在游戏架构上考虑到了不信任客户端。 So I don't want my view to get direct access to _col
. 所以我不希望我的视图直接访问_col
。
@observe
class MyView extends Component {
...
componentWillMount(){
this.id = this.props.params.id;
autorun(()=>{
this.props.store.has(this.id)
//do something smart
}
}
...
}
What could be the alternatives? 可能有哪些替代方案?
You can just use 你可以使用
public has(id) { return _col.has(id); public has(id){return _col.has(id); } }
For observables it doesn't matter whether they are accessed directly or through several layers of indirection, MobX will track it anyways. 对于可观察对象而言,无论是直接访问还是通过多层间接访问它们都无关紧要,MobX无论如何都会跟踪它。
