Class KeyMemcacheService

java.lang.Object

com.googlecode.objectify.cache.KeyMemcacheService

public class KeyMemcacheService
extends Object

Like MemcacheService but translates keys and values into forms more palatable to the low level service. Also protects against no-ops (empty collections). Also stores a sentinel value for null and replaces it with null on fetch. Memcached doesn't store nulls (the old GAE SDK hid this from us).
