Method Summary

protected AbstractBeanFactoryBasedTargetSource createBeanFactoryBasedTargetSource(Class beanClass, String beanName)
          Subclasses must implement this method to return a new AbstractPrototypeBasedTargetSource if they wish to create a custom TargetSource for this bean, or null if they are not interested it in, in which case no special target source will be created.

protected abstract PoolingAttribute getPoolingAttribute(Class beanClass, String beanName)
          Create a PoolingAttribute for the given bean, if any.

protected AbstractPoolingTargetSource newPoolingTargetSource(PoolingAttribute poolingAttribute)
          Create a new AbstractPoolingTargetSource.

Method Detail

createBeanFactoryBasedTargetSource

protected final AbstractBeanFactoryBasedTargetSource createBeanFactoryBasedTargetSource(Class beanClass,
                                                                                        String beanName)

Description copied from class: AbstractBeanFactoryBasedTargetSourceCreator

Subclasses must implement this method to return a new AbstractPrototypeBasedTargetSource if they wish to create a custom TargetSource for this bean, or null if they are not interested it in, in which case no special target source will be created. Subclasses should not call setTargetBeanName or setBeanFactory on the AbstractPrototypeBasedTargetSource: This class' implementation of getTargetSource() will do that.

Specified by:: createBeanFactoryBasedTargetSource in class AbstractBeanFactoryBasedTargetSourceCreator

Parameters:: beanClass - the class of the bean to create a TargetSource for; beanName - the name of the bean
Returns:: the AbstractPrototypeBasedTargetSource, or null if we don't match this

newPoolingTargetSource

protected AbstractPoolingTargetSource newPoolingTargetSource(PoolingAttribute poolingAttribute)

Create a new AbstractPoolingTargetSource. This implementation creates a CommonsPoolTargetSource, but subclasses may wish to override that behavior (potentially even using different pools for specific PoolingAttribute subclasses).

The created AbstractPoolingTargetSource does not have to be configured, This will all be handled by this TargetSourceCreator and its base class.

See Also:: CommonsPoolTargetSource

getPoolingAttribute

protected abstract PoolingAttribute getPoolingAttribute(Class beanClass,
                                                        String beanName)

Create a PoolingAttribute for the given bean, if any.

Parameters:: beanClass - the class of the bean to create a TargetSource for; beanName - the name of the bean
Returns:: the PoolingAttribute, or null for no pooling
