Examples of ungetService()

com.dotcms.repackage.org.osgi.framework.BundleContext.ungetService()
org.apache.felix.ipojo.ServiceContext.ungetService()
Ungets the service reference. The service reference must comes from this service context. @param reference the reference to unget @return true if you are the last user of the reference. @see org.osgi.framework.BundleContext#ungetService(org.osgi.framework.ServiceReference)
org.jboss.gravia.runtime.ModuleContext.ungetService()
Releases the service object referenced by the specified {@code ServiceReference} object. If the context module's use count forthe service is zero, this method returns {@code false}. Otherwise, the context module's use count for the service is decremented by one.
The service's service object should no longer be used and all references to it should be destroyed when a module's use count for the service drops to zero.
The following steps are required to unget the service object:
1. If the context module's use count for the service is zero or the service has been unregistered, {@code false} is returned.
2. The context module's use count for this service is decremented by one.
3. If the context module's use count for the service is currently zero and the service was registered with a {@code ServiceFactory} object, the{@link ServiceFactory#ungetService(Module,ServiceRegistration,Object)}method is called to release the service object for the context module.
4. {@code true} is returned.
@param reference A reference to the service to be released. @return {@code false} if the context module's use count for the serviceis zero or if the service has been unregistered; {@code true}otherwise. @throws IllegalStateException If this ModuleContext is no longer valid. @throws IllegalArgumentException If the specified{@code ServiceReference} was not created by the same frameworkinstance as this {@code ModuleContext}. @see #getService(ServiceReference) @see ServiceFactory
org.osgi.framework.BundleContext.ungetService()
Releases the service object for the service referenced by the specified {@code ServiceReference} object. If the context bundle's use count forthe service is zero, this method returns {@code false}. Otherwise, the context bundle's use count for the service is decremented by one.
The service object must no longer be used and all references to it should be destroyed when a bundle's use count for the service drops to zero.
The following steps are required to release the service object:
1. If the context bundle's use count for the service is zero or the service has been unregistered, {@code false} is returned.
2. The context bundle's use count for the service is decremented by one.
3. If the context bundle's use count for the service is now zero and the service has {@link Constants#SCOPE_BUNDLE bundle} or{@link Constants#SCOPE_PROTOTYPE prototype} scope, the{@link ServiceFactory#ungetService(Bundle,ServiceRegistration,Object)}method is called to release the service object for the context bundle.
4. {@code true} is returned.
@param reference A reference to the service to be released. @return {@code false} if the context bundle's use count for the serviceis zero or if the service has been unregistered; {@code true}otherwise. @throws IllegalStateException If this BundleContext is no longer valid. @throws IllegalArgumentException If the specified{@code ServiceReference} was not created by the same frameworkinstance as this {@code BundleContext}. @see #getService(ServiceReference) @see ServiceFactory
org.osgi.framework.ServiceFactory.ungetService()
Releases a service object customized for a bundle.
The Framework invokes this method when a service has been released by a bundle. The service object may then be destroyed.
If this method throws an exception, a framework event of type {@link FrameworkEvent#ERROR} is fired containing a service exception oftype {@link ServiceException#FACTORY_EXCEPTION} with the thrown exceptionas the cause. @param bundle The bundle releasing the service. @param registration The {@code ServiceRegistration} object for theservice being released. @param service The service object returned by a previous call to the{@link #getService(Bundle,ServiceRegistration) getService}method. @see BundleContext#ungetService(ServiceReference)
