I have a class that is expensive to construct, in terms of time and memory. I'd like to maintain a pool of these things and dispense them out on demand to multiple threads in the same process. Is...

What is object pooling and what is a weak object reference ? How can we implement them using Java?

What is the proper way to use ArrayPool with reference types? I was assuming that it would be full of objects that were just 'newed up' with the default constructor. For example, in the code bel...

I am building a UDP-based application that receives and sends multiple packets. I could build a new DatagramPacket for each send, or I recycle one instance for the life of my application. Are ...

Is it possible to create a generic object pool that creates new objects inside it? Plus it would be nice if this object creation could receive parameters. public interface IPoolable { void Disp...

I'm currently trying to build some code execution optimization for a contest, and was looking at the ObjectPool pattern to favor object reuse instead of new object instantiation. I've put together...

I need to create a pool of socket connections which will be served to multiple worker threads. Is there a thread safe object pool implementation with functionality similar to Apache Commons' ...

How would I write a generic InternPool<T> in Java? Does it need a Internable interface? String in Java has interning capabilities; I want to intern classes like BigDecimal and Account.

EDIT: One more piece of possibly relevant info: The use case in which I see the problem is tab switching. That is, I create view X on tab A, remove it when leaving tab A, then recycle it into tab B...

Does the following basic object pool work? I have a more sophisticated one based on the same idea (i.e. maintaining both a Semaphore and a BlockingQueue). My question is - do I need both Semaphore ...

I'm on a webservice server and I have objects with an internal connection. Initializing this connection takes really long so my idea was to use an object pool to reuse the connections among differe...

I am trying to develop an ObjectPool, which can be used with any Object without changing the source of neither the Pool nor the Object - but I can´t find any way to write the get()-function ("Mainc...

I'm looking for a modern implementation of an object pool in Java. I can see the apache commons one, but to be honest, I'd rather one that uses generics, and the concurrency stuff from more r...

My requirement is very simple to understand. I want to call a web service from my Java web application with restriction of maximum 10 webservice calls per minute. Just after 1 minute, I can establ...

We use a number of large objects. Ideally, we'd like to make all of them permanently available to client code, but they don't fit in physical memory all at once. So when we approach memory limits, ...

I don't necessarily mean implemented using the singleton pattern, but rather, only having and using one instance of a pool. I don't like the idea of having just one pool (or one per pooled type). H...

When should one prefer object pool over dynamically allocated objects? I need to create and destroy thousands of objects per second. Is it by itself enough to decide in favor of object pool? Than...

It's my understanding that in Spring, all objects are treated by default as singletons. If singleton is set to false, then a new object will be served at each request. But what if I wanted to poo...
