All Implemented Interfaces:

Factory, HandlerFactory, TrackerCustomizer, ManagedServiceFactory

public class HandlerManagerFactory
extends ComponentFactory
implements HandlerFactory

Implementation of the handler factory interface. This factory is able to create handler manager. A handler manager is an iPOJO instance containing a handler object.

Constructor Detail

HandlerManagerFactory

public HandlerManagerFactory(BundleContext context,
                             Element metadata)
                      throws ConfigurationException

Creates a handler factory.

Parameters:

context - the bundle context

metadata - the metadata of the component to create

Throws:

ConfigurationException - if the element describing the factory is malformed.

Method Detail

getNamespace

public String getNamespace()

Description copied from interface: HandlerFactory

Gets the namespace associated with this handler factory.

Specified by:

getNamespace in interface HandlerFactory

Returns:

the namespace used by this handler

getHandlerName

public String getHandlerName()

Description copied from interface: HandlerFactory

Gets the name associated with this handler factory.

Specified by:

getHandlerName in interface HandlerFactory

Returns:

the name used by this handler

getType

public String getType()

Description copied from interface: HandlerFactory

Gets the type of the handler factory. The handler can only be plugged on instance container with the same type. Basically, types are primitive and composite.

Specified by:

getType in interface HandlerFactory

Returns:

the type of the handler

getStartLevel

public int getStartLevel()

Description copied from interface: HandlerFactory

Gets the start level of the handler objects created by this factory. Handlers with a low start level are configured and started before handlers with an higher start level. Moreover, these handlers are stopped and disposed after.

Specified by:

getStartLevel in interface HandlerFactory

Returns:

the handler's start level

getComponentTypeDescription

public ComponentTypeDescription getComponentTypeDescription()

Description copied from class: ComponentFactory

Gets the component type description of the current factory.

Overrides:

getComponentTypeDescription in class ComponentFactory

Returns:

the description of the component type attached to this factory.

See Also:

IPojoFactory.getComponentTypeDescription()

stopping

public void stopping()

Stops the factory. This method does not disposed created instances. These instances will be disposed by the instance managers. This method is called with the lock.

Overrides:

stopping in class ComponentFactory

createInstance

public ComponentInstance createInstance(Dictionary configuration,
                                        IPojoContext context,
                                        HandlerManager[] handlers)
                                 throws ConfigurationException

Creates an instance. The given configuration needs to contain the 'name' property. This method is called when holding the lock.

Overrides:

createInstance in class ComponentFactory

Parameters:

configuration - the configuration of the created instance.

context - the service context to push for this instance.

handlers - the handler array to attach to the instance.

Returns:

the created HandlerManager.

Throws:

ConfigurationException - if the instance configuration failed.

See Also:

Factory.createComponentInstance(java.util.Dictionary)

getRequiredHandlerList

public List getRequiredHandlerList()

Computes required handlers. This method does not manipulate any non-immutable fields, so does not need to be synchronized. This method is overridden to avoid using the same detection rules than 'primitive' components. Indeed, architecture is disable by default, and a handler is never immediate.

Overrides:

getRequiredHandlerList in class ComponentFactory

Returns:

the required handler list.
