Constructor Detail

UserSecurityGroupsCache

public UserSecurityGroupsCache(IdcClient idcClient,
                               int cacheMaxSize,
                               long timeToLive)

Create a security implementation that checks Security Groups

Parameters:

idcClient - RIDC connection information

cacheMaxSize - Number of entries (userids) to keep in LRU cache

timeToLive - Number of milliseconds before an entry is too old

Method Detail

initializeCache

public void initializeCache(int maxSize,
                            long timeToLive)

Initialize the cache with maximum size and length to live

Specified by:

initializeCache in interface IUserSecurityCache

Parameters:

maxSize - Assuming an LRU cache, the maximum number of entries

timeToLive - positive number of milliseconds for each entry to be valid

Parameters:

userContext -

Returns:

a cacheId to be used in future fetches

removeCacheId

public DataBinder removeCacheId(CacheId id)

Drop the permissions for this user from the cache

Specified by:

removeCacheId in interface IUserSecurityCache

Parameters:

id - CacheID

Returns:

DataBinder permissions removed from cache or null
