Class MapDB.PackedStringKeySerializer<K extends Comparable<K>>

java.lang.Object

org.mapdb.BTreeKeySerializer<K>

org.modeshape.jcr.index.local.MapDB.PackedStringKeySerializer<K>

Type Parameters:

K - the type to be serialized

All Implemented Interfaces:

Serializable, MapDB.KeySerializerWithComparator<K>

Enclosing class:

MapDB

public static class MapDB.PackedStringKeySerializer<K extends Comparable<K>>
extends org.mapdb.BTreeKeySerializer<K>
implements Serializable, MapDB.KeySerializerWithComparator<K>

Applies delta packing on java.lang.String. This serializer splits consequent strings to two parts: shared prefix and different suffix. Only suffix is than stored.
