Interface MetaDataPlugin

public interface MetaDataPlugin

The mean of the interface is to provide machanism for defining new manifest headers for providing metadata by a XML resource. It also has the responsibility of instructing the MetaDataManager service how to process the metatype providers created from the parsed XMLs. When registered as service into the framework instances of this interface should include property METADATA in its registration properties with String array value which specifies metatype bundle manifest headers which are of interest.
Normally there will be only one plugin per type but if more, the type should be considered storable if any of them requires so.
