getIfRecentOrPut

public <T> T getIfRecentOrPut(String key,
 T object,
 long timeToLive,
 TemporalUnit unit)

If the given key exists and the entry is no older than the given timeToLiveMinutes, return the object stored under the key, otherwise store the given object under the given key and return it

Type Parameters:

T -

Parameters:

key - the identifier under which to store the object

object - the object to store under the given key if the key doesn't exist yet or is older than timeToLiveMinutes

timeToLive - the maximum age in the given time unit the stored object may have to be returned. If it's older, it will be replaced with the passed object

unit - The TemporalUnit in which the timeToLive parameter is given

Returns:

the object stored under the given key if viable, otherwise the given object
