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();
