Constructor Detail
SoftReferenceObjectPool
public SoftReferenceObjectPool()(Code)



SoftReferenceObjectPool
public SoftReferenceObjectPool(PoolableObjectFactory factory)(Code)



SoftReferenceObjectPool
public SoftReferenceObjectPool(PoolableObjectFactory factory, int initSize) throws Exception(Code)




Method Detail
addObject
public synchronized void addObject() throws Exception(Code)
Create an object, and place it into the pool. addObject() is useful for "pre-loading" a pool with idle objects.



borrowObject
public synchronized Object borrowObject() throws Exception(Code)



clear
public synchronized void clear()(Code)



close
public synchronized void close() throws Exception(Code)



getNumActive
public synchronized int getNumActive()(Code)



getNumIdle
public synchronized int getNumIdle()(Code)
Returns an approximation not less than the of the number of idle instances in the pool.



invalidateObject
public synchronized void invalidateObject(Object obj) throws Exception(Code)



returnObject
public synchronized void returnObject(Object obj) throws Exception(Code)



setFactory
public synchronized void setFactory(PoolableObjectFactory factory) throws IllegalStateException(Code)
