Method Detail

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

Throws:

org.springframework.beans.BeansException

addParameter

public void addParameter(java.lang.String askFor,
                         java.lang.Object valueParam)
                  throws ContainerConfigurationException

Description copied from class: DefaultContainer

Add a parameter to the container as a possibility for injection

Overrides:

addParameter in class DefaultContainer

Parameters:

askFor - The key that will be looked up

valueParam - The value to be returned from the key lookup

Throws:

ContainerConfigurationException - If the specified beans could not be used

getBean

public java.lang.Object getBean(java.lang.String id)

Description copied from interface: Container

Get the contained instance of a bean/setting of a given name.

Specified by:

getBean in interface Container

Overrides:

getBean in class DefaultContainer

Parameters:

id - The type to get an instance of

Returns:

The object of the given type, or null if the object does not exist

getBeanNames

public java.util.Collection<java.lang.String> getBeanNames()

Description copied from interface: Container

Get a list of all the available beans. Implementation of this method is optional so it is valid for this method to return an empty collection, but to return Objects when queried directly using Container.getBean(String). This method should only be used for debugging purposes.

Specified by:

getBeanNames in interface Container

Overrides:

getBeanNames in class DefaultContainer

Returns:

A collection containing all the available bean names.

contextDestroyed

public void contextDestroyed()

Description copied from interface: Container

This should be called only by DwrListener. It requests all reverse ajax threads to stop.

GenericServlet.destroy() is called only when all connections are closed. If a DwrListener is configured then we can close down the connections in a timely way. All other tidy-up is done by Container.servletDestroyed() which will work even when a DwrListener has not been configured.

Specified by:

contextDestroyed in interface Container

Specified by:

contextDestroyed in interface UninitializingBean

Overrides:

contextDestroyed in class DefaultContainer

See Also:

Container.servletDestroyed()

servletDestroyed

public void servletDestroyed()

Description copied from interface: Container

Should be called only by DwrServlet (or other servlet implementations). It requests all other threads to stop, and any tidy-up that can be done after the context has been fully destroyed.

Specified by:

servletDestroyed in interface Container

Specified by:

servletDestroyed in interface UninitializingBean

Overrides:

servletDestroyed in class DefaultContainer

See Also:

Container.contextDestroyed()
