Why doesnt ReferenceMap support Phantom references? #107

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I really need to use PhantomReferences as keys in ReferenceMap, but it 
doesn not seem to support them.

Is there a technical reason why that is so?

PhantomReference.get() always returns null, so there would be no way to compare 
the
keys. What are you trying to do?

I am instrumenting classes and collecting data about their objects till they 
are 
GC'd. Using a WeakReference means I cant collect any data on the finalize() 
method.

Sounds like you want to use FinalizablePhantomReference directly.
