Interface SourceExtractor

All Known Implementing Classes:
  NullSourceExtractor, PassThroughSourceExtractor

    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.
