Method Detail

getCacheKey

public Object getCacheKey()

Get the key with which this object is cached.

getCachedObject

public Object getCachedObject()

Get the value that has been cached.

isExpired

public boolean isExpired()

Determine whether this cache entry has expired.

Returns:

true if the object has expired

getCacheTime

public long getCacheTime()

Get the timestamp at which this object was cached.

getLastAccessTime

public long getLastAccessTime()

Get the timestamp of the last access.

setAccessTime

public void setAccessTime(long t)

Set the timestamp of a particular access. Implementations are expected to increment their access count and determine whether this particular access time is mroe recent than their current latest access time (which may be the case if the notifications are asynchronous).

Parameters:

t - a timestamp indicating access

getAccessCount

public int getAccessCount()

Get the number of times this object has been accessed.
