Method Detail

initializeEntry

void initializeEntry(Object key,
                     FarragoObjectCache.UninitializedEntry entry)

Initializes a cache entry.

Parameters:

key - key of the object to be constructed

entry - to initialize by calling its FarragoObjectCache.UninitializedEntry.initialize(java.lang.Object, long, boolean) method; failing to call initialize will lead to a subsequent assertion (unless an exception is thrown to indicate initialization failure)

isStale

boolean isStale(Object value)

Tests a cached object for staleness.

Returns:

true if object is stale, meaning it must not be returned from a pin call, and should be discarded from the cache when detected
