Class CommonsPoolObjectPool

java.lang.Object

org.mule.util.pool.CommonsPoolObjectPool

All Implemented Interfaces:

Disposable, Initialisable, ObjectPool

Direct Known Subclasses:

DefaultLifecycleEnabledObjectPool

public class CommonsPoolObjectPool
extends Object
implements ObjectPool

CommonsPoolProxyPool is an implementation of ObjectPool that internally uses the commons-pool GenericObjectPool and uses a ObjectFactory for creating new pooled instances.

Constructor Detail

CommonsPoolObjectPool

public CommonsPoolObjectPool(ObjectFactory objectFactory,
                     PoolingProfile poolingProfile,
                     MuleContext muleContext)

Creates a new pool and an Object factory with the ServiceDescriptor

Method Detail

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

getPooledObjectFactory

protected org.apache.commons.pool.PoolableObjectFactory getPooledObjectFactory()

Template method to be overridden by implementations that do more than just invoke objectFactory

applyInitialisationPolicy

protected void applyInitialisationPolicy()
                                  throws Exception

Throws:

Exception

borrowObject

public Object borrowObject()
                    throws Exception

Specified by:

borrowObject in interface ObjectPool

Throws:

Exception

returnObject

public void returnObject(Object object)

Specified by:

returnObject in interface ObjectPool

getNumActive

public int getNumActive()

Specified by:

getNumActive in interface ObjectPool

getMaxActive

public int getMaxActive()

Specified by:

getMaxActive in interface ObjectPool

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

clear

public void clear()

Specified by:

clear in interface ObjectPool

close

public void close()

Specified by:

close in interface ObjectPool

setObjectFactory

public void setObjectFactory(ObjectFactory objectFactory)

Specified by:

setObjectFactory in interface ObjectPool

getObjectFactory

public ObjectFactory getObjectFactory()

Specified by:

getObjectFactory in interface ObjectPool
