Interface DelegatedExecutionOsgiBundleApplicationContext

All Superinterfaces:

ApplicationContext, ApplicationEventPublisher, BeanFactory, ConfigurableApplicationContext, ConfigurableOsgiBundleApplicationContext, HierarchicalBeanFactory, Lifecycle, ListableBeanFactory, MessageSource, ResourceLoader, ResourcePatternResolver

All Known Implementing Classes:

AbstractDelegatedExecutionApplicationContext, OsgiBundleXmlApplicationContext, OsgiBundleXmlWebApplicationContext

public interface DelegatedExecutionOsgiBundleApplicationContext
extends ConfigurableOsgiBundleApplicationContext

Interface that redirect the application context crucial methods to a third party executor to allow the initialization to be executed in stages. The interface splits the refresh method in two parts: startRefresh() and completeRefresh().

Note: This interface is intended for usage only inside Spring-DM framework. Relying on this interface is highly discouraged.

Method Detail

normalRefresh

void normalRefresh()

Non-delegated refresh operation (execute ConfigurableApplicationContext.refresh() in the traditional way).

See Also:

ConfigurableApplicationContext.refresh()

normalClose

void normalClose()

Non-delegated close operation (execute ConfigurableApplicationContext.close() in the traditional way).

See Also:

ConfigurableApplicationContext.close()

startRefresh

void startRefresh()

First phase of the refresh. Normally, this just prepares the beanFactory but does not instantiates any beans.

completeRefresh

void completeRefresh()

The second, last phase of the refresh. Executes after a certain condition, imposed by the executor, has been met. Finishes the rest of the refresh operation. Normally, this operations performs most of the refresh work, such as instantiating singletons.

setExecutor

void setExecutor(OsgiBundleApplicationContextExecutor executor)

Assigns the OsgiBundleApplicationContextExecutor for this delegated context.

Parameters:

executor - the executor of this application context, to which the refresh method is delegated to

setDelegatedEventMulticaster

void setDelegatedEventMulticaster(OsgiBundleApplicationContextEventMulticaster multicaster)

Allows a delegated OsgiBundleApplicationContextEventMulticaster, external to the application context, to be used for sending OSGi application context events regarding the application context life cycle. This method is mainly intended for monitoring the context lifecycle by third parties (such as the OSGi extender). It's up to the implementation to decide whether this setter method is required or not.

Parameters:

multicaster - the application multicaster used for sending events triggered by the delegated execution.

See Also:

OsgiBundleApplicationContextEvent

getDelegatedEventMulticaster

OsgiBundleApplicationContextEventMulticaster getDelegatedEventMulticaster()

Returns the OSGi event multicaster (if any) associated with this application context.

Returns:

the OSGi event multicaster associated with this context
