Enum DuplicateFilter.KeepMode
java.lang.Object
java.lang.Enum<DuplicateFilter.KeepMode>
org.apache.lucene.sandbox.queries.DuplicateFilter.KeepMode
- All Implemented Interfaces:
- Serializable, Comparable<DuplicateFilter.KeepMode>
- Enclosing class:
- DuplicateFilter
public static enum DuplicateFilter.KeepMode
- extends Enum<DuplicateFilter.KeepMode>
KeepMode determines which document id to consider as the master, all others being
identified as duplicates. Selecting the "first occurrence" can potentially save on IO.
KM_USE_FIRST_OCCURRENCE
public static final DuplicateFilter.KeepMode KM_USE_FIRST_OCCURRENCE
KM_USE_LAST_OCCURRENCE
public static final DuplicateFilter.KeepMode KM_USE_LAST_OCCURRENCE

- Returns:
- an array containing the constants of this enum type, in

public static DuplicateFilter.KeepMode valueOf(String name)
- Returns the enum constant of this type with the specified name.
