it9good/dorkbox_objectpool

Fast, lightweight, and compatible blocking/non-blocking/soft-reference object pool for Java 6+

ObjectPool

This provides an ObjectPool, for providing for a safe, and fixed sized pool of objects. This is only recommended in systems were garbage collection is to be kept to a minimum, and the created objects are large.

• This is for cross-platform use, specifically - linux 32/64, mac 32/64, and windows 32/64. Java 11+

Usage:

    val <T> pool = ObjectPool.nonBlocking(PoolObject<T>() {
        /**
         * Called when an object is returned to the pool, useful for resetting an objects state, for example.
         */
         fun onReturn(`object`: Foo) {
            object.foo = 0;
            object.bar = null;
         }
    
         /**
          * Takes an object from the pool, if there is no object available, will create a new object.
          */
          fun onTake(`object`: Foo) {
          }
    
          /**
           * @return a new object instance created by the pool.
           */
          override fun newInstance(): Foo {
             return Foo();
          }
        });


    val foo = pool.take()
    pool.put(foo)
