| Method Summary | |
void |
addObject()
Create an object, and place it into the pool. |
Object |
borrowObject()
Obtain an instance from my pool. |
void |
clear()
Clears any objects sitting idle in the pool, releasing any associated resources (optional operation). |
void |
close()
Close this pool, and free any resources associated with it. |
int |
getNumActive()
Return the number of instances currently borrowed from my pool (optional operation). |
int |
getNumIdle()
Returns an approximation not less than the of the number of idle instances in the pool. |
void |
invalidateObject(Object obj)
Invalidates an object from the pool By contract, obj MUST have been obtained using borrowObject
or a related method as defined in an implementation
or sub-interface. |

returnObject(Object obj)
Return an instance to my pool. |
void |
setFactory(PoolableObjectFactory factory)

public void invalidateObject(Object obj)
throws Exception
ObjectPoolborrowObject
or a related method as defined in an implementation
or sub-interface.
This method should be used when an object that has been borrowed
is determined (due to an exception or other problem) to be invalid.
If the connection should be validated before or after borrowing,
then the PoolableObjectFactory.validateObject(java.lang.Object) method should be
used instead.
