方法详细资料

makeObject

public java.lang.Object makeObject()
                            throws java.lang.Exception

用于在必要时产生新的对象

指定者:

makeObject 在接口中 PoolableObjectFactory

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.

activateObject

public void activateObject(java.lang.Object obj)
                    throws java.lang.Exception

用于将对象“激活”――设置为适合开始使用的状态

指定者:

activateObject 在接口中 PoolableObjectFactory

参数:

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.

PoolableObjectFactory.destroyObject(T)

passivateObject

public void passivateObject(java.lang.Object obj)
                     throws java.lang.Exception

用于将对象“挂起”――设置为适合开始休眠的状态

指定者:

passivateObject 在接口中 PoolableObjectFactory

参数:

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.

另请参阅:

PoolableObjectFactory.destroyObject(T)

validateObject

public boolean validateObject(java.lang.Object obj)

用于校验一个具体的对象是否仍然有效，已失效的对象会被自动交给destroyObject方法销毁

指定者:

validateObject 在接口中 PoolableObjectFactory

参数:

obj - the instance to be validated

返回:

false if obj is not valid and should be dropped from the pool, true otherwise.

destroyObject

public void destroyObject(java.lang.Object obj)
                   throws java.lang.Exception

用于销毁被validateObject判定为已失效的对象

指定者:

destroyObject 在接口中 PoolableObjectFactory

参数:

obj - the instance to be destroyed

抛出:

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