15 | Specifies a CacheManagerEventListenerFactory which will be used to create a CacheManagerPeerProvider, which
|
||
16 | is notified when Caches are added or removed from the CacheManager.
|
||
17 | |||
18 | The attributes of CacheManagerEventListenerFactory are:
|
||
19 | - class - a fully qualified factory class name
|
||
20 | - properties - comma separated properties having meaning only to the factory.
|
||
21 | |||
22 | Sets the fully qualified class name to be registered as the CacheManager event listener.
|
||
23 | |||
24 | The events include:
|
||
25 | - adding a Cache
|
||
26 | - removing a Cache
|
||
27 | |||
28 | Callbacks to listener methods are synchronous and unsynchronized. It is the responsibility of the implementer
|
||
29 | to safely handle the potential performance and thread safety issues depending on what their listener is doing.
|
||
30 | |||
31 | If no class is specified, no listener is created. There is no default.

39 | The following attributes are required:
|
||
40 | |||
41 | maxElementsInMemory - Sets the maximum number of objects that will be created in memory
|
||
42 | eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the
|
||
43 | element is never expired.
|
||
44 | overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
|
||
45 | has reached the maxInMemory limit.
|
||
46 | |||
47 | The following attributes are optional:
|
||
48 | timeToIdleSeconds - Sets the time to idle for an element before it expires.
|
||
49 | i.e. The maximum amount of time between accesses before an element expires
|
||
50 | Is only used if the element is not eternal.
|
||
51 | Optional attribute. A value of 0 means that an Element can idle for infinity.
|
||
52 | The default value is 0.
|
||
53 | timeToLiveSeconds - Sets the time to live for an element before it expires.
|
||
54 | i.e. The maximum time between creation time and when an element expires.
|
||
55 | Is only used if the element is not eternal.
|
||
56 | Optional attribute. A value of 0 means that and Element can live for infinity.
|
||
57 | The default value is 0.
|
||
58 | diskPersistent - Whether the disk store persists between restarts of the Virtual Machine.
|
||
59 | The default value is false.
|
||
60 | diskExpiryThreadIntervalSeconds- The number of seconds between runs of the disk expiry thread. The default value
|
||
61 | is 120 seconds.
|
||
62 | memoryStoreEvictionPolicy - Policy would be enforced upon reaching the maxElementsInMemory limit. Default
|
||
63 | policy is Least Recently Used (specified as LRU). Other policies available -
|

64 | First In First Out (specified as FIFO) and Less Frequently Used
