从IType实例化对象

Question

I would like to know if Eclipse JDT is offering any API functions to instantiate an object from an IType .

We are using the Eclipse JDT search engine to retrieve classes with a particular interface, say Application that looks like this:

public interface Application {
    void launch();
}

Using the JDT search engine, we are able to get an IType object that represents a class that implements the Application interface. Assume that the implementing class has a no-argument constructor.

What we try to achieve is to get a concrete Object from the IType . So, I would like to know if the JDT offers any API functions to do so.

If it does, we will use it to instantiate the IType . If it doesn't, we will locate the containing projects, build a ClassLoader from it and then use reflection to instantiate the class directly.

Thansk in advance, Matt

Answer 1

Nope. Reflection is the way to go.
