Class ObjectPool.ObjectFactory

java.lang.Object
  org.sadun.util.pool.ObjectPool.BaseFactory
      org.sadun.util.pool.ObjectPool.ObjectFactory

All Implemented Interfaces:

ObjectPool.Factory, java.io.Serializable

Enclosing class:

ObjectPool

public static class ObjectPool.ObjectFactory

extends ObjectPool.BaseFactory

An ExtendedObjectPool.Factory implementation which uses reflection to create instances of a certain class.

After creation, objects can be optionally setup by an user-provided class implementing the Setup interface.

Constructor Detail

ObjectPool.ObjectFactory

public ObjectPool.ObjectFactory(java.lang.Class cls,
                                java.lang.Object[] params,
                                Setup ps)

Create a factory which will construct object of the given class, with the given parameters, using the given Setup object.

The construction parameter types are deduced from the types of the passed parameter objects, and a compatible constructor is searched for.

Parameters:

cls - the class of the object to build

params - the construction parameters to use, or null

ps - the Setup object to be used for post-construction setup, or null

ObjectPool.ObjectFactory

public ObjectPool.ObjectFactory(java.lang.String clsName,
                                java.lang.Object[] params,
                                Setup ps)

Create a factory which will construct object of the given class, with the given parameters, using the given Setup object.

The construction parameter types are deduced from the types of the passed parameter objects, and a compatible constructor is searched for.

Parameters:

clsName - the name of class of the object to build

params - the construction parameters to use, or null

ps - the Setup object to be used for post-construction setup, or null

Method Detail

create

public java.lang.Object create()

Create an instance of the class defined at construction, using the (optional) parameters and the (optional) Setup object defined at construction for construction and post-construction initialization.

Specified by:

Specified by:

create in class ObjectPool.BaseFactory

Returns:

the newly created object

Throws:

ObjectPoolException - if there is a problem creating the object

destroy

public void destroy(java.lang.Object obj)

This implementation does not do anything.

Specified by:

destroy in interface ObjectPool.Factory

Overrides:

destroy in class ObjectPool.BaseFactory
