Question

来自现有的代码库。 A类的实例变量A.toBeCalled为“ToBeCalled”类型。如何找到它的所有用法/参考A.toBeCall来自代码库的整个调用图？ e.g。

B类调用A.getToBeCalled（）并存储在其本地var中，然后通过调用其方法来使用它。
B类调用A.getToBeCalled（）并存储在C类的实例var中，然后D类使用C类的实例var。

要求：

调用A.toBeCalled对象的方法在B类，C类，D类中完成... e.t.c
上面的被调用者图

代码示例

Class A {
   ToBeCalled toBeCalled = new ToBeCalled();
   getToBecalled() { return toBeCalled;}
}

Class B {      
  main() {
    A a = new A();
    ToBeCalled toBeCalledInB = a.getToBecalled();
    toBeCalledInB.doXXX();
    C c = new C();
    c.setToBeCalled(toBeCalledInB);
    D d = new D();
    d.start(c);
  }
}

Class C {
  ToBeCalled toBeCalledInC;
  setToBeCalled(ToBeCalled theToBeCalled){
    toBeCalledInC = theToBeCalled;
  }
  getToBeCalled() {
    return toBeCalledInC;
  }
}

Class D {
  start(C c) {
    ToBeCalled toBeCalledInD = c.getToBeCalled();
    toBeCalledInD.doYYY();
  }
}

调用A.toBeCalled的列表方法

ToBeCalled.doXXX（）
ToBeCalled.doYYY（）

我调查了几个工具作为起点，然而，它们有点粗糙

非常感谢您的帮助。

如果我理解你的问题，那你就是在谈论interfaces。假设你有几个方法接口MyItf：

public interface MyItf {
public ToBeCalled getToBeCalled();
public void doXXX();
public void doYYY();
}

使用interface ToBeCalled类必须覆盖所有方法。

public class ToBeCalled implements MyItf{

@Override
public ToBeCalled getToBeCalled() {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void doXXX() {
    // TODO Auto-generated method stub
}

@Override
public void doYYY() {
    // TODO Auto-generated method stub
    }
}

其他课程：

public class ToBeCalled2 implements MyItf{

@Override
public ToBeCalled getToBeCalled() {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void doXXX() {
    // TODO Auto-generated method stub
}

@Override
public void doYYY() {
    // TODO Auto-generated method stub
    }
}

最后：

public class Launcher {


public static void main(String[] args) {
    MyItf my = new ToBeCalled();        
    my.getToBeCalled();     
    my.doXXX();     
    my.doYYY();

            my = new ToBeCalled2();     
    my.getToBeCalled();     
    my.doXXX();     
    my.doYYY();
}
}

如何在调用图中找到实例变量对象的所有用法？
