Apache Software Foundation: Mailing Lists. or "better" pool implementation comes along, we can simply drop it into our ReaderUtil You can also try to set your pool.setMaxTotal(-1); like this which is supposed to allow as many objects as you need. We can, for example, use this factory with the GenericObjectPool to instantiate our activateObject(org.apache.commons.pool2.PooledObject) is invoked on every instance that has been passivated before it is borrowed from the pool. Used by sub-classes to include the fields defined by the sub-class in the. you can try that, I think it's an older version of apache-commons-pool (~2012). By contract, clients must return the borrowed instance Let's further assume that a complete pool implementation will be provided via a … makeObject() is called whenever a new instance is needed. Socket-Apache-Commons-Pool2. (A pool of StringBuffers may or may not be useful in practice.We're just using it as a simple example here.) It is a demo about how to use the socket server and client. Here's the code for the ReaderUtil, implemented without an ObjectPool: For the sake of this example, let's assume we want to pool the StringBuffers implementations).

When coupled with the appropriate PoolableObjectFactory, GenericObjectPool provides robust pooling functionality for arbitrary objects. This Chevy features a 350 CID V8 that was rebuilt along with the 700R4 transmission roughly 2500 miles ago. This stated, there are still no examples on the official website. Recall that Pool provides a simple toolkit for creating object pools. then call returnObject when we're done with it. For instance the purposes of BasePoolableObjectFactory are not similar to BasePooledObjectFactory.. like this: Since we've constrained ourselves to the ObjectPool interface, an arbitrary pool StringBuffers as used above.
