OFF-TOPIC: weak references
This is actually about java in general I just to assure I understood the concept of WeakHashMap. What is weak referenced in this map is the keys, right? So, let's say I have a WeakHashMap and a HashMap, both with the same key/value pairs. When I remove an object from the HashMap the garbage collector will remove its REFERENCE in the WeakHashMap object, but not necessarily the object, correct? -- Felipe Schnack Analista de Sistemas [EMAIL PROTECTED] Cel.: (51)91287530 Linux Counter #281893 Faculdade Ritter dos Reis www.ritterdosreis.br [EMAIL PROTECTED] Fone/Fax.: (51)32303328 -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: OFF-TOPIC: weak references
If you still have a reference to the object in the HashMap the object won't be gced. The weak hash map is just a weak hash map, not a weak application in the appropriate sense.

Re: OFF-TOPIC: weak references
Yes, so the reference to my object is gc'd, not the object itself (as long its key is not strongly referenced anywhere else) when I remove an object from the HashMap right?

The object is not gced. That is right.
