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.
