Class MemcachedStorageCapabilities

java.lang.Object

org.opensaml.storage.impl.memcached.MemcachedStorageCapabilities

All Implemented Interfaces:

StorageCapabilities, StorageCapabilitiesEx

public class MemcachedStorageCapabilities
extends Object
implements StorageCapabilitiesEx

Provides a description of memcached capabilities. Note that only value size is configurable since memcached supports increasing the maximum slab size via the -I flag. MemcachedStorageService supports arbitrarily large context names and keys by hashing values longer than 250 bytes, which is the maximum size allowed.

Field Summary

Method Summary

Modifier and Type	Method	Description
int	getContextSize()	Gets max size of context labels in characters.
int	getKeySize()	Gets max size of keys in characters.
long	getValueSize()	Gets max size of values in characters.
boolean	isClustered()	Returns true iff the storage implementation manages data independent of a single server node.
boolean	isServerSide()	Returns true iff the storage implementation manages data independent of the client.
