Class MemcachedCacheEntryImpl

java.lang.Object
  org.apache.http.impl.client.cache.memcached.MemcachedCacheEntryImpl

All Implemented Interfaces:

MemcachedCacheEntry

public class MemcachedCacheEntryImpl
extends Object
implements MemcachedCacheEntry

Default implementation of MemcachedCacheEntry. This implementation simply uses Java serialization to serialize the storage key followed by the HttpCacheEntry into a byte array.

Constructor Summary

MemcachedCacheEntryImpl()

MemcachedCacheEntryImpl(String key, HttpCacheEntry httpCacheEntry)

Method Summary

HttpCacheEntry	getHttpCacheEntry() Returns the HttpCacheEntry associated with this entry.
String	getStorageKey() Returns the storage key associated with this entry.
void	set(byte[] bytes) Given a serialized representation of a MemcachedCacheEntry, attempt to reconstitute the storage key and HttpCacheEntry represented therein.
byte[]	toByteArray() Returns a serialized representation of the current cache entry.

Method Detail

toByteArray

public byte[] toByteArray()

Description copied from interface: MemcachedCacheEntry

Returns a serialized representation of the current cache entry.

Specified by:

toByteArray in interface MemcachedCacheEntry

getStorageKey

public String getStorageKey()

Description copied from interface: MemcachedCacheEntry

Returns the storage key associated with this entry. May return null if this is an "unset" instance waiting to be MemcachedCacheEntry.set(byte[]) with a serialized representation.

Specified by:

getStorageKey in interface MemcachedCacheEntry

getHttpCacheEntry

public HttpCacheEntry getHttpCacheEntry()

Description copied from interface: MemcachedCacheEntry

Returns the HttpCacheEntry associated with this entry. May return null if this is an "unset" instance waiting to be MemcachedCacheEntry.set(byte[]) with a serialized representation.

Specified by:

getHttpCacheEntry in interface MemcachedCacheEntry

set

public void set(byte[] bytes)

Description copied from interface: MemcachedCacheEntry

Given a serialized representation of a MemcachedCacheEntry, attempt to reconstitute the storage key and HttpCacheEntry represented therein. After a successful call to this method, this object should return updated (as appropriate) values for MemcachedCacheEntry.getStorageKey() and MemcachedCacheEntry.getHttpCacheEntry(). This should be viewed as an atomic operation on the MemcachedCacheEntry.

Specified by:

set in interface MemcachedCacheEntry

Parameters:

bytes - serialized representation
