Description

Distribution has one main component (agent) and several secondary components (triggers, exporters and importers).

These can be created as java objects using a DistributionComponentFactory. The core framework provides a DefaultDistributionComponentFactory that will create the components implemented in the core but a client can define its own components and factory and the default component factory will use those to create a component it does not know of.

The core framework also provides two ways of registering such a java object as an OSGI service:
1. using osgi configs, the osgi properties are parsed and passed to the factory, a component is created and registered (GenericDistributionComponentFactory)
2. resource configs, the properties of a resource are parsed and passed to the factory, a component is created and registered (ResourceBasedDistributionComponentFactory)

Components registered as OSGI services are available as resources via OsgiServicePropertiesResourceProvider.
