public void put(String key, Object value, int ttl)
CacheServiceStore an item into the cache service by key and set ttl value
put in interface CacheServicekey - the cache keyvalue - the object to be cachedttl - time to live of the cached item. Time unit is second. If set to negative number, then it will never expire. If set to zero then the default ttl value will be usedpublic void put(String key, Object value)
CacheServiceStore an item into the cache by key and use default ttl
put in interface CacheServicekey - the cache keyvalue - the object to be cachedpublic void evict(String key)
CacheServiceRemove an item from the cache service by key

CacheServiceReturn an item from the cache service by key

CacheServiceIncrease an number type value associated with key key by 1
If no value is associated with the key, then it will associate number 1 to key and return 0.
incr in interface CacheServicekey - the key index the numeric valuepublic int incr(String key, int ttl)
CacheServiceIncrease an number type value associated with key key with expires specified
If no value is associated with the key, then it will associate number 1 to key and return 0.

CacheServiceDecrease an number type value associated with key key by 1
If no value is associated with the key, then it will associate number -1 to key and return 0.

CacheServiceDecrease an number type value associated with key key by 1 with expires specified
If no value is associated with the key, then it will associate number -1 to key and return 0.

CacheServiceSet default ttl value which will be used if user pass 0 as ttl or not specified ttl Note some service might not favor this method after the internal cache service is initialized. E.g. memcached and ehcaches
