[jira] [Resolved] (FELIX-3740) Maintain the MetaTypeProvider
service tracker on the MetaTypeService
[ https://issues.apache.org/jira/browse/FELIX-3740?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Felix Meschberger resolved FELIX-3740.
--------------------------------------
Resolution: Fixed
Assignee: Felix Meschberger
Implemented a single ServiceTracker for ManagedService[Factory] services instread of tracking the services in each MetaTypeInformationImpl object in Rev. r1403227. Now the MetaTypeInformationImpl objects are just data containers and are not linked to service tracking and registered in the framework. This also reduces the number of service listeners.
In Rev. r1403229 streamline the trackers for ManagedService[Factory] and MetaTypeProvider to align and simplify them.
This resolves this issue.

> As of FELIX-3184 support for MetaTypeProvider service has been added with a MetaTypeProviderTracker service tracker. This is so far created and started for each MetaTypeInformationImpl instance. This makes cleanup of the tracker hard.
> Instead this tracker should be maintained on the MetaTypeServiceImpl and respective MetaTypeProvider services injected into the MetaTypeInformationImpl objects handed out by the service.
> Likewise, the ManagedService[Factory] services implementing the MetaTypeProvider interface should be tracked in the MetaTypeServiceImpl rather than in the ServiceMetaTypeInformation objects. The trick here is to only provide such MetaTypeProviders to MetaTypeInformationImpl objects not reading meta type information from descriptors.
