Interface ConstructorCallback<T>

Type Parameters:

T - The class that will be sampled with this ConstructorCallback

public interface ConstructorCallback<T>

This interface describes a function that is used to sample a constructor. It is intended to be invoked every time a constructor for class T is invoked. This will not be invoked when subclasses of T are instantiated. This mechanism works independently of whether the class is part of the JDK core library.
