net.spy.memcached

Class BaseCacheMap<V>

java.lang.Object

net.spy.memcached.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.

Constructor Detail

BaseCacheMap

public BaseCacheMap(MemcachedClientIF c,
                    int expiration,
                    java.lang.String prefix,
                    Transcoder<V> t)

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
