## Interface Slice

-     public interface Slice

  An interface specifying in which slice database records are read or written based on the given key. If this interface is not used, then the entire contents of the key are used to determine which slice contains a given database record. Use this interface only if a portion of the key should be used to determine slice placement.

  You configure the database with this handler using the `DatabaseConfig.setSliceCallback(com.sleepycat.db.Slice)` method.
