Method Detail

getFromCache

public V getFromCache(K key)

Description copied from interface: ApplicationCache

Obtains a stored entry from the cache. Implementations must make sure not to throw an exception even if one occurs here.

Parameters:

key - the unique identifier to use for fetching the entry; be advised that the same identifier must be used for saving the details into the cache

Returns:

a populated entry object containing enough information to facilitate the function it is required for; if none is found

putInCache

public void putInCache(K key,
                       V entry)

Description copied from interface: ApplicationCache

Places an entry in the cache. The key is the identifier used to subsequently retrieve the entry.

Parameters:

key - the key corresponding to which entry must be stored in the cache

entry - the object entry to place into the cache

evictFromCache

public void evictFromCache(K key)

Description copied from interface: ApplicationCache

Removes the specified entry from the cache. The key is the identifier used to remove the entry. If the entry is not found, the method should simply return (not throw an exception).

Some cache implementations may not support eviction from the cache, in which case they should provide appropriate behavior to alter the token in either its documentation, via an exception, or through a log message.

Parameters:

key - the predefined key/identifier for evicting an entry from the cache
