@FunctionalInterface public interface SourceExtractor
Simple strategy allowing tools to control how source metadata is attached to the bean definition metadata.

Configuration parsers may provide the ability to attach source metadata during the parse phase. They will offer this metadata in a generic format which can be further modified by a SourceExtractor before being attached to the bean definition metadata.
