public abstract class BaseKeyedPoolableObjectFactory<K, V> implements KeyedPoolableObjectFactory<K, V> {
    
Create an instance that can be served by the pool.

Parameters:
key the key used when constructing the object
Returns:
an instance that can be served by the pool
    public abstract V makeObject(K key)
        throws Exception;

    
Destroy an instance no longer needed by the pool.

The default implementation is a no-op.

Parameters:
key the key used when selecting the instance
obj the instance to be destroyed
    public void destroyObject(K key, V obj)
        throws Exception {
    }

    
Ensures that the instance is safe to be returned by the pool.

The default implementation always returns true.

Parameters:
key the key used when selecting the object
obj the instance to be validated
Returns:
always true in the default implementation
 
    public boolean validateObject(K key, V obj) {
        return true;
    }

    
Reinitialize an instance to be returned by the pool.

The default implementation is a no-op.

Parameters:
key the key used when selecting the object
obj the instance to be activated
    public void activateObject(K key, V obj)
        throws Exception {
    }

    
Uninitialize an instance to be returned to the idle object pool.

The default implementation is a no-op.

Parameters:
key the key used when selecting the object
obj the instance to be passivated
    public void passivateObject(K key, V obj)
        throws Exception {
    }
