Does Java have anything akin to a smart pointer for referenced objects?
Posted on 2003-10-30
I am using hashtables to hold shared values (resources). When the values stored in the hashtable are no longer referenced externally, I wish to have the value reference in the hashtable removed so the value object can be garbage collected. Thus I have two related questions:
1) How in Java can one tell how many references there are to a given object?
2) Is there some Java equivalent to a C++ smart pointer class but for references?
