NSAutoreleasePool

Overview

An autorelease pool is used to manage Foundation’s autorelease mechanism for Objective-C objects. NSAutoreleasePool provides Java applications access to autorelease pools. Typically it is not necessary for Java applications to use NSAutoreleasePools since Java manages garbage collection. However, some situations require an autorelease pool; for instance, if you start off a thread that calls Cocoa, there won’t be a top-level pool.

You know you need an autorelease pool when you see “no pool in place - just leaking” warnings coming from your Cocoa Java application. Just wrap pools around the places where you have top-level Java threads calling into Cocoa. Use code like the following to accomplish this task:

int myPool = NSAutoreleasePool.push();

// Your code here

NSAutoreleasePool.pop(myPool);
