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();
|
