Interface SitemapExtensionProvider
To provide an implementation for a defined sub type of
Extension
an
SitemapExtensionProvider
needs to be registered as OSGI service.
In order to hide the implementation detail of an extension from the the consumer API, the return type of
newInstance()
is AbstractExtension
, the provider facing API of the extension.
However to use the returned instance, it has to also implement the extension sub type interface and be registered
with it's full qualified class name.
There may be multiple SitemapExtensionProvider
s using the same namespace. If so the one with the highest ranking
according to the OSGI specification will define the namespace's prefix, which means that lower ranking services
may use another prefix then they were registered with.
