Class PassThroughSourceExtractor

    java.lang.Object
      org.springframework.beans.factory.parsing.PassThroughSourceExtractor

All Implemented Interfaces:
  SourceExtractor

    public class PassThroughSourceExtractor

extends Object
implements SourceExtractor

Simple `SourceExtractor` implementation that just passes the candidate source metadata object through for attachment.

Using this implementation means that tools will get raw access to the underlying configuration source metadata provided by the tool.

This implementation should not be used in a production application since it is likely to keep too much metadata in memory (unnecessarily).

Since:
  2.0
