Class CollectableReference<T>

java.lang.Object

java.lang.ref.Reference<T>

java.lang.ref.PhantomReference<T>

org.mule.tck.util.CollectableReference<T>

Type Parameters:

T - The referent type.

public class CollectableReference<T>
extends PhantomReference<T>

Utility class created for leak testing. It extends a PhantomReference and implements a Hamcrest Matcher which checks that the reference is enqueued, because it means that there isn't any strong reference pointing to the referent object. Usage example:

 
     CollectableReference<String> collectableReference = new CollectableReference<>(new String("Hello world"));
     System.out.println(collectableReference.get());
     assertThat(collectableReference, is(eventually(collectedByGc())));
