Examples of org.eclipse.core.runtime.spi.RegistryContributor

org.eclipse.core.runtime.spi.RegistryContributor
This class describes a registry contributor which is an entity that supplies information to the extension registry. Depending on the registry strategy, contributor might delegate some of its functionality to a "host" contributor. For instance, OSGi registry strategy uses "host" contributor to delegate some functionality from fragments to plug-ins.
This class can be instantiated by the registry Service Providers.
This class can be used without OSGi running.
This class can not be extended.
Note: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
