Method Detail

getNotifier

ListenerNotifier getNotifier()

setListeners

public void setListeners(OsgiServiceRegistrationListener[] listeners)

Sets the listeners interested in registration and unregistration events.

Parameters:

listeners - registration/unregistration listeners.

destroy

public void destroy()

Specified by:

destroy in interface org.springframework.beans.factory.DisposableBean

registerService

abstract void registerService()

Registers/Exports the OSGi service.

unregisterService

abstract void unregisterService()

Unregisters/de-exports the OSGi service.

setLazyListeners

public void setLazyListeners(boolean lazyListeners)

Sets the laziness of the exporter listeners. Eager listeners (default) will cause the listeners to be called when the service is being exported. In contract, if true is passed, the listeners will be called not when the service is registered but after the first bundle actually requests it or another component requests the service registration. "Lazy listeners" are the equivalent of lazy activated service managers in Blueprint Service (OSGi 4.2).

Parameters:

lazyListeners - false if the listeners should be called when the service is registered, true if the invocations should occur after the first service/factory bean request

getLazyListeners

public boolean getLazyListeners()
