Class DataRestrictionCache

java.lang.Object

psdi.mbo.DataRestrictionCache

All Implemented Interfaces:

MaximoCache, FixedLoggerNames, FixedLoggers

public class DataRestrictionCache
extends java.lang.Object
implements MaximoCache, FixedLoggers

Maximo cache to keep track which group data security specified for an app, object, attribute. The cache is accessd by everywhere when it needs to check wether a restriction needs to be processed. No where else has information regarding who has the data restriction. We keep this centralized cache to avoid updating more than one place when a restriction is added, deleted or modified. TODO: In development and not completed or finalized. Pending the merge rules if any for the restrictions for the groups that the user all belong. The data structure of the cache has a great chance of chaning too. Also need to decide if a cache for each user should also be keped in a least referenced fashion in order to avoid fetching the restrictions for its multiple groups everytime.

getName

public java.lang.String getName()

Description copied from interface: MaximoCache

Returns the name of the cache object. Should be unique within the app server. This name is used to uniquely identify the cache object among all cached object for both accessing the cache object as well as refreshing the cache object. Ex. MaximoDD returns "MAXIMODD"
