Method Detail

bindCdoSessionService

public void bindCdoSessionService(CdoSessionService cdoSessionService)

Bind method for discovered service.

Parameters:

service - The discovered service.

unbindCdoSessionService

public void unbindCdoSessionService(CdoSessionService service)

Unbind method for discovered service.

Parameters:

service - The removed service.

bindVmiService

public void bindVmiService(IVMIService vmiService)

Bind method for discovered VMI service.

Parameters:

vmiService - The discovered VMI service.

unbindVmiService

public void unbindVmiService(IVMIService vmiService)

Unbind the VMI service. This only causes the VMI service to be disconnected if the same VMI service is set for this cyclic optimiser.

Parameters:

vmiService - The VMI service to be disconnected.

bindOptimisationService

public void bindOptimisationService(OptimisationServiceRegistry optimisationService)

Bind the optimisation service to be used by this.

Parameters:

optimisationService - The optimisation service to be used.

unbindOptimisationService

public void unbindOptimisationService(OptimisationServiceRegistry optimisationService)

Unbind the optimisation service used by the cyclic optimiser.

Parameters:

optimisationService - The service that is unbound. this only enacts the unbinding if the service to be disconnected equals the set service.

handleEvent

public void handleEvent(org.osgi.service.event.Event event)

Notifies the cyclic optimiser. This will re-check the configuration of the CDOSessionService configured via bindCdoSessionService(CdoSessionService). If the CDO session service has been initialised, the cyclic optimiser will be started.

Specified by:

handleEvent in interface org.osgi.service.event.EventHandler

Parameters:

event - The triggered event.

serviceChanged

public void serviceChanged(org.osgi.framework.ServiceEvent event)

Specified by:

serviceChanged in interface org.osgi.framework.ServiceListener
