## org.mule.util.pool
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.

Field Summary
`protected static Log` | `logger` logger used by this class
`protected MuleContext` | `muleContext`
`protected ObjectFactory` | `objectFactory` The ObjectFactory used to create new pool instances
`protected GenericObjectPool` | `pool` The pool
`protected PoolingProfile` | `poolingProfile` The pooling profile used to configure and initialise pool

Fields inherited from interface org.mule.api.lifecycle.Disposable
`PHASE_NAME`

Constructor Summary
`CommonsPoolObjectPool(ObjectFactory objectFactory, PoolingProfile poolingProfile, MuleContext muleContext)` Creates a new pool and an Object factory with the ServiceDescriptor

Method Summary
`protected void` | `applyInitialisationPolicy()`
`Object` | `borrowObject()`
`void` | `clear()`
`void` | `close()`
`void` | `dispose()` A lifecycle method where implementor should free up any resources.
`int` | `getMaxActive()`
`int` | `getNumActive()`
`ObjectFactory` | `getObjectFactory()`
`protected PoolableObjectFactory` | `getPooledObjectFactory()` Template method to be overridden by implementations that do more than just invoke objectFactory
`void` | `initialise()` Method used to perform any initialisation work.
`void` | `returnObject(Object object)`
`void` | `setObjectFactory(ObjectFactory objectFactory)`

Field Detail

### logger

    protected static final Log logger

  logger used by this class

### pool

    protected GenericObjectPool pool

  The pool

### objectFactory

    protected ObjectFactory objectFactory

  The ObjectFactory used to create new pool instances

### poolingProfile

    protected PoolingProfile poolingProfile

  The pooling profile used to configure and initialise pool

### muleContext

    protected MuleContext muleContext

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 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`
