Service for installing/updating/removing installable resources InstallableResource in an OSGi framework. The resources are provided by provider components which are clients of this API. For example a file directory provider might scan a directory in the file system and provide the artifacts contained in the configured directory. When such a client starts it should first call registerResources(String, InstallableResource[]) and inform this service about all available resources. In the case of a file directory provider, this list would contain all files found in the directory (and sub directories). This is the rendezvous point. The OSGi installer service compares this complete list with previous lists it might have and triggers corresponding tasks like installing new artifacts and uninstalling removed artifacts. Once this rendezvous has been done between a client and the OSGi installe, the client calls updateResources(String, InstallableResource[], String[]) to inform about changes like new resources or removed resources. A single provider should never call these methods in parallel, before calling any method a previous call must have finished! The OSGi installer detects the resources and based on their type and metadata, the installer decides whether to install them, update an already installed artifact or simply ignore them. For example, for bundles the symbolic name and the version is used.
