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 6+

Usage:

    ObjectPool<T> pool = ObjectPool.NonBlocking(new PoolableObject<T>() {
            /**
             * Called when an object is returned to the pool, useful for resetting an objects state, for example.
             */
            public
            void onReturn(T object) {
                object.foo = 0;
                object.bar = null;
            }
    
            /**
             * Called when an object is taken from the pool, useful for setting an objects state, for example.
             */
            public
            void onTake(T object) {
            }
    
            /**
             * Called when a new instance is created
             */
            @Override
            public
            T create() {
                return new Object();
            }
        });
        
        

    /**
     * Takes an object from the pool. If the pool is a {@link BlockingPool}, this will wait until an item is available in
     * the pool.
     * <p/>
     * This method catches {@link InterruptedException} and discards it silently.
     */
    T take();

    /**
     * Takes an object from the pool. If the pool is a {@link BlockingPool}, this will wait until an item is available in the pool.
     */
    T takeInterruptibly() throws InterruptedException;

    /**
     * Return object to the pool. If the pool is a {@link BlockingPool}, this will wake the threads that have blocked during take/takeInterruptibly()
     */
    void put(T object);

    /**
     * @return a new object instance created by the pool.
     */
    T newInstance();
