Java - how to analyze a function code

We are working with mvc design pattern, where all the data is stored under map.

I want to iterate over all the classes in the system and for each to check what the method is putting on the map and what does the method get from the map.

For example for the next code:

private void myFunc()
{
Object obj = model.get("mykey");
Object obj2 = model.get("mykey2");
.....
model.put("mykey3", "aaa");
}


I want to know that in this function we have 2 gets: mykey and mykey2 and 1 put: mykey3

How can I do it with the code.

Thanks.

You tagged this with "reflection", but that will not work.

Reflection only allows you to inspect "signatures". You can use it to identify the methods of a class, and the arguments of the methods.

It absolutely doesn't help you to identify what each method is doing.

In order to find out about that, you would need to either parse the java source code side, or byte code classes. As in: write code that reads that content, and understands "enough" of it to find such places. Which is a very challenging effort.
