## com.sleepycat.je.util
Class DbScavenger

    java.lang.Object
      com.sleepycat.je.util.DbDump
          com.sleepycat.je.util.DbScavenger

    public class DbScavenger

extends DbDump

Used to retrieve as much data as possible from a corrupted environment. This utility is meant to be used programmatically, and is the equivalent to the -R or -r options for `DbDump`.

To scavenge a database:

      DbScavenger scavenger =
          new DbScavenger(env, outputDirectory, , , );
      scavenger.dump();

The recovered databases will put placed in the outputDirectory with ".dump" file suffixes. The format of the .dump files will be suitable for use with DbLoad.
