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:
- Map<String,V>
- Direct Known Subclasses:
- CacheMap
public class BaseCacheMap<V>
- extends Object
- implements Map<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.

BaseCacheMap
public BaseCacheMap(MemcachedClientIF c,
int expiration,
String prefix,
Transcoder<V> t)
- Build a BaseCacheMap.
- Parameters:
c
- the underlying clientexpiration
- the expiration for objects set through this Mapprefix
- a prefix to ensure objects in this map are uniquet
- the transcoder to serialize and deserialize objects
clear
public void clear()
- Specified by:
clear
in interface Map<String,V>
containsKey
public boolean containsKey(Object key)
- Specified by:
containsKey
in interface Map<String,V>
containsValue
public boolean containsValue(Object value)
- This method always returns false, as truth cannot be determined without
iteration.
- Specified by:
