Configuration data for caches.
May specify either or both or maxItems and maxDuration.
If the maxDuration is specified as zero caching will be effectively disabled (regardless of the value of maxItems). If maxItems is less than 1 the configuration is invalid. If maxDuration is negative the configuration is invalid. If purgePeriod is not positive the configuration is invalid.

The maximum number of items that should be stored in the cache. When more items than this are in the cache they are purged eldest first. Must be >= 1. |
|
The maximum age of items in the cache. Items older than this are purged from the cache. If set to zero the cache will only ever contain a single item. If set, must not be negative. Configuration files should specify this using ISO860 Duration format, i.e. PT10S. |
||
The purge period for the cache. If the purge period is null items will only be removed from the cache when they expire and space is required. When purge period is set a scheduled task runs that explicitly removes from the cache any invalid items. If set, must be positive. Configuration files should specify this using ISO860 Duration format, i.e. PT10S. |
