Examples of PoolableObjectFactory

org.apache.commons.pool.PoolableObjectFactory
An interface defining life-cycle methods for instances to be used in an {@link ObjectPool ObjectPool}.
By contract, when an {@link ObjectPool ObjectPool}delegates to a PoolableObjectFactory,
1. {@link #makeObject makeObject} is called whenever a new instance is needed.
2. {@link #activateObject activateObject} is invoked on every instance before it is returned from the pool.
3. {@link #passivateObject passivateObject} is invoked on every instance when it is returned to the pool.
4. {@link #destroyObject destroyObject} is invoked on every instance when it is being "dropped" from the pool (whether due to the response from {@link #validateObject validateObject}, or for reasons specific to the pool implementation.)
5. {@link #validateObject validateObject} is invoked in an implementation-specific fashion to determine if an instance is still valid to be returned by the pool. It will only be invoked on an {@link #activateObject "activated"}instance.

org.datanucleus.store.rdbms.datasource.dbcp.pool.PoolableObjectFactory
An interface defining life-cycle methods for instances to be served by an {@link ObjectPool}.
By contract, when an {@link ObjectPool}delegates to a {@link PoolableObjectFactory},
1. {@link #makeObject makeObject}is called whenever a new instance is needed.
2. {@link #activateObject activateObject}is invoked on every instance that has been {@link #passivateObject passivated} before it is{@link ObjectPool#borrowObject borrowed} from the pool.
3. {@link #validateObject validateObject}is invoked on {@link #activateObject activated} instances to make surethey can be {@link ObjectPool#borrowObject borrowed} from the pool.validateObject may also be used to test an instance being {@link ObjectPool#returnObject returned} to the poolbefore it is {@link #passivateObject passivated}. It will only be invoked on an activated instance.
4. {@link #passivateObject passivateObject}is invoked on every instance when it is returned to the pool.
5. {@link #destroyObject destroyObject}is invoked on every instance when it is being "dropped" from the pool (whether due to the response from validateObject, or for reasons specific to the pool implementation.) There is no guarantee that the instance being destroyed will be considered active, passive or in a generally consistent state.
{@link PoolableObjectFactory} must be thread-safe. The only promisean {@link ObjectPool} makes is that the same instance of an object will notbe passed to more than one method of a PoolableObjectFactory at a time.
