Method Detail

put

public final V put(K key,
    V data,
    long timeToLive,
    long maxIdleTime)
            throws CacheException

Description copied from interface: CustomTtlCache

Store an entry in the cache with a specific time to live and max idle time.

Specified by:

put in interface CustomTtlCache<K,V>

data - The data to store, make sure that you don't alter the data after it has been put to cache as (depending on the implementation) this might lead to altering the entry in the cache. Use the returned entry instead.

timeToLive - The time (in milliseconds) after which the entry expires.

maxIdleTime - The time (in milliseconds) that an entry may idle (not being accessed) before being expunged.

Returns:

The entry that has been stored in the cache. It is save to alter this as implementations as implmentations make sure that this is always a copy.

Throws:

CacheException - Thrown if the storage fails.

put

public final V put(K key,
    V data,
    long timeToLive)
            throws CacheException

Description copied from interface: CustomTtlCache

Store an entry in the cache with a specific time to live.

Specified by:

put in interface CustomTtlCache<K,V>

data - The data to store, make sure that you don't alter the data after it has been put to cache as (depending on the implementation) this might lead to altering the entry in the cache. Use the returned entry instead.

timeToLive - The time (in milliseconds) after which the entry expires.

Returns:

The entry that has been stored in the cache. It is save to alter this as implementations as implmentations make sure that this is always a copy.

Throws:

CacheException - Thrown if the storage fails.

      V data)
           throws CacheException

Description copied from class: AbstractMapBackedCache
