public void activateObject(java.lang.Object key,
java.lang.Object obj)
throws java.lang.Exception
The default implementation is a no-op.
activateObject in interface KeyedPoolableObjectFactorykey - the key used when selecting the objectobj - the instance to be activated
java.lang.Exception - if there is a problem activating obj,
this exception may be swallowed by the pool.KeyedPoolableObjectFactory.destroyObject(java.lang.Object, java.lang.Object)
public void destroyObject(java.lang.Object key,
java.lang.Object obj)
throws java.lang.Exception
The default implementation is a no-op.
destroyObject in interface KeyedPoolableObjectFactorykey - the key used when selecting the instanceobj - the instance to be destroyed
java.lang.Exception - should be avoided as it may be swallowed by
the pool implementation.KeyedPoolableObjectFactory.validateObject(java.lang.Object, java.lang.Object),
KeyedObjectPool.invalidateObject(java.lang.Object, java.lang.Object)
public abstract java.lang.Object makeObject(java.lang.Object key)
throws java.lang.Exception
makeObject in interface KeyedPoolableObjectFactorykey - the key used when constructing the object
java.lang.Exception - if there is a problem creating a new instance,
this will be propagated to the code requesting an object.
public void passivateObject(java.lang.Object key,
java.lang.Object obj)
throws java.lang.Exception
The default implementation is a no-op.
passivateObject in interface KeyedPoolableObjectFactorykey - the key used when selecting the objectobj - the instance to be passivated
java.lang.Exception - if there is a problem passivating obj,
this exception may be swallowed by the pool.KeyedPoolableObjectFactory.destroyObject(java.lang.Object, java.lang.Object)
public boolean validateObject(java.lang.Object key,
java.lang.Object obj)
The default implementation always returns true.
validateObject in interface KeyedPoolableObjectFactorykey - the key used when selecting the objectobj - the instance to be validated
true in the default implementation
