public BaseKeyedPoolableObjectFactory()

方法详细资料

makeObject

public abstract V makeObject(K key)
                      throws java.lang.Exception

Create an instance that can be served by the pool.

指定者:

makeObject 在接口中 KeyedPoolableObjectFactory<K,V>

参数:

key - the key used when constructing the object

返回:

an instance that can be served by the pool

抛出:

java.lang.Exception - if there is a problem creating a new instance, this will be propagated to the code requesting an object.

destroyObject

public void destroyObject(K key,
                          V obj)
                   throws java.lang.Exception

Destroy an instance no longer needed by the pool.

The default implementation is a no-op.

指定者:

destroyObject 在接口中 KeyedPoolableObjectFactory<K,V>

参数:

key - the key used when selecting the instance

obj - the instance to be destroyed

抛出:

java.lang.Exception - should be avoided as it may be swallowed by the pool implementation.

validateObject

public boolean validateObject(K key,
                              V obj)

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

The default implementation always returns true.

指定者:

validateObject 在接口中 KeyedPoolableObjectFactory<K,V>

参数:

key - the key used when selecting the object

obj - the instance to be validated

返回:

always true in the default implementation

activateObject

public void activateObject(K key,
                           V obj)
                    throws java.lang.Exception

Reinitialize an instance to be returned by the pool.

The default implementation is a no-op.

指定者:

activateObject 在接口中 KeyedPoolableObjectFactory<K,V>

参数:

key - the key used when selecting the object

obj - the instance to be activated

抛出:

java.lang.Exception - if there is a problem activating obj, this exception may be swallowed by the pool.

KeyedPoolableObjectFactory.destroyObject(K, V)

passivateObject

public void passivateObject(K key,
                            V obj)
                     throws java.lang.Exception

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

The default implementation is a no-op.

指定者:

passivateObject 在接口中 KeyedPoolableObjectFactory<K,V>

参数:

key - the key used when selecting the object

obj - the instance to be passivated

抛出:

java.lang.Exception - if there is a problem passivating obj, this exception may be swallowed by the pool.
