GWT: Native method using JSNI: how to call methods dynamically

Question

I am using GWT and I have created a native method that calls the method cmd_addspace in the class EverlinkedActions and it works fine for now:

private static native String execute(String functionName,  Object[] vParams)/*-{
  try{          
      @es.gwt.client.dash.actions.impl.EverlinkedActions::cmd_addspace([Ljava/lanG/Object;)(vParams);          
  }catch(e){
      alert(e.message);
  }

}-*/;

How can i make the method name dynamic? it means instead of "cmd_addspace" i want to call the method "functionName" which its name is passed as argument in the native method.

And is their a way to make the class name also dynamic? i want to have something like that:

private static native String execute(String className, String functionName,  Object[] vParams)/*-{
  try{          
      @es.gwt.client.dash.actions.impl.className::functionName([Ljava/lanG/Object;)(vParams);          
  }catch(e){
      alert(e.message);
  }

}-*/;

Thanks for any help

不确定你想在这里实际实现什么，但恐怕 JSNI 不会那样工作。

诸如此类的代码@es.gwt.client.dash.actions.impl.EverlinkedActions::cmd_addspace([Ljava/lanG/Object;)(vParams);需要在编译时成为完全可解析的符号，因为类和方法名称会被替换为其最小化版本。
