Class FileMemData.Cache<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

org.h2.store.fs.mem.FileMemData.Cache<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>, SequencedMap<K,V>

Enclosing class:

FileMemData

static class FileMemData.Cache<K,V>
extends LinkedHashMap<K,V>

This small cache compresses the data if an element leaves the cache.
