Method Detail

getWeakRef

public static MyWeakRef getWeakRef(java.lang.Object o)

equals

public boolean equals(java.lang.Object obj)

Only one PersistentWeakRef is ever constructed for a particular object. Thus, this PWR is equal to obj iff they are the same weak reference, or if obj is the referent of this.

Overrides:

equals in class MyWeakRef

get

public java.lang.Object get()

Return the referent while it's alive; after it is destroyed, return this. TODO: Is it sound to always return 'this' instead?

Overrides:

get in class java.lang.ref.Reference
