get

public Object get(String key)

Specified by:

get in interface DataStorage

olderThan

public boolean olderThan(String key,

 Object object)

Specified by:

put in interface DataStorage

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

getIfRecentOrPut

public <T> T getIfRecentOrPut(String key,
 T object,
 long timeToLiveMinutes)

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 - Type of the object to put

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

timeToLiveMinutes - the maximum age in minutes the stored object may have to be returned. If it's older, it will be replaced with the passed object

Returns:

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

getIfRecentOrRemove

public <T> Optional<T> getIfRecentOrRemove(String key,
 long timeToLiveMinutes)

getIfRecentOrRemove

public <T> Optional<T> getIfRecentOrRemove(String key,
 long timeToLive,
 TemporalUnit unit)

Get an object stored under the given key. If the object is older than the given time to live, it is removed and an empty Optional returned

Type Parameters:

T - Type of the object to get/remove

Parameters:

key - key of the object to get/remove

timeToLive - objects put within this timespan are returned, older objets are removed

unit - time unit of 'timeToLive'

Returns:

An optional containing the requested object, or an empty optional if the key doesn't exist or the object is older than 'timeToLive'
