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.

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
