Inject a class from a passed in string of fully qualified classname.

[hambone]

I am writing an API and I want the client to be able to pass in a fully qualified class as a param.

UseApi api = new UseApi("com.company.classes.thisClass");

api.process();

Can I use Guice to take a fully qualified class string and inject the class in the code that implements process() as an example. In my code I want to be able to say

public class UseApi {

   public final String clazz;

  public UseApi ( String clazz ) {

    this.clazz = clazz;

  }

  public void process()

  {

     // inject an instance of com.company.classes.thisClass

    Object theirClass = inject this.clazz

    theirClass.someMethod();

  {

}

This assumes I also have access to the compiled passed in class.

Thank you so much in advance

Can't you use Class.forName("classname") to get injectable class?

You should be able to do this, so long as you're not playing crazy games with classloaders. Class.forName() is not advisable, as you don't always get the right classloader. But in principle this can work.
