Hi,


I'd like to build memory limited cache. For example configure it, that objects hold by this cache cannot occupy more than 2 MB. The problem is, how to "measure" object. There is no standard method in Java, as I know.


Is there any way how to do this? If not, I will probably use Runtime.getFreeMemory(), which is far from perfect. Any other idea? Thanks

Have you looked towards piping the ObjectOutputStream with, say, ByteArrayOutputStream? ByteArrayOutputStream has method size(), which seems to be what you need.
