Class FileMemData.Cache<K,​V>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​V>
    Enclosing class:
    FileMemData

    static class FileMemData.Cache<K,​V>
    extends java.util.LinkedHashMap<K,​V>
    This small cache compresses the data if an element leaves the cache.
