Package net.spy.memcached

Class BaseCacheMap<V>

  • Type Parameters:
    V - the type of value taken and returned by this Map's underlying transcoder, and thus taken and returned by this Map.
    All Implemented Interfaces:
    java.util.Map<java.lang.String,​V>
    Direct Known Subclasses:
    CacheMap
    public class BaseCacheMap<V>
extends java.lang.Object
implements java.util.Map<java.lang.String,​V>
    Base class for a Map interface to memcached.

    This Map interface makes memcached a bit easier to use for some purposes by providing a limited Map implementation.

    Do note that nothing that iterates over the map will work (such is memcached). All iteration mechanisms will return empty iterators and such.

        Build a BaseCacheMap.
        Parameters:
        c - the underlying client
        expiration - the expiration for objects set through this Map
        prefix - a prefix to ensure objects in this map are unique
        t - the transcoder to serialize and deserialize objects
