Configuration parameters

This registry implementation supports following configuration parameters:

isValidating

Regulates is registry should use validating parser when loading plug-in manifests. The default parameter value is true.

stopOnError

Regulates is registry should stop and throw RuntimeException if an error occurred while PluginRegistry.register(URL[]) registering or PluginRegistry.unregister(String[]) un-registering plug-ins. If this is false, the registration errors will be stored in the internal report that is available with PluginRegistry.checkIntegrity(PathResolver) method. The default parameter value is false.

1. Collect all currently registered extension points.
2. Parse given URL's as XML content files and separate them on plug-in and plug-in fragment descriptors.
3. Process new plug-in descriptors first:
   1. Instantiate new PluginDescriptorImpl object.
   2. Handle versions correctly - register new descriptor as most recent version or as an old version.
   3. If other versions of the same plug-in already registered, take their fragments and register them with this version.
4. Process new plug-in fragments next:
   1. Instantiate new PluginFragmentImpl object.
   2. Check if older version of the same fragment already registered.

   1. Instantiate new PluginFragmentImpl object.
   2. Check if older version of the same fragment already registered. If yes, un-register it and move to old plug-in fragments collection.
   3. Register new fragment with all matches plug-in descriptors (if this fragment is of most recent version).
5. Notify collected extension points about potential changes in extensions set.
6. Propagate events about registry changes.
