Method Detail

setAllDependencies

void setAllDependencies(ICacheEntry entry,
                        IThingIDList thingIDs)
                 throws CacheException

Clears all dependencies, and then sets the list to thingIDs

Parameters:

entry - entry of object to set deps on

thingIDs - array of thing ID's

Throws:

CacheException - On invalid entry or DB error

clearDependencies

void clearDependencies(ICacheEntry entry)
                throws CacheException

removed all dependencies for this entry

Parameters:

entry - valid entry

Throws:

CacheException - if invalid entry or DB error

addDependencies

void addDependencies(ICacheEntry entry,
                     IThingIDList thingIDs)
              throws CacheException

Adds a list of dependencies to the entry.

Parameters:

entry - valid entry

thingIDs - array of thingID

Throws:

CacheException - on invalid entry or DB error

removeDependencies

void removeDependencies(ICacheEntry entry,
                        IThingIDList thingIDs)
                 throws CacheException

Removes specific dependencies

Parameters:

entry - valid entry

thingIDs - array of thingID's

Throws:

CacheException - on invalid entry or DB error

invalidateByDep

void invalidateByDep(IThingID thingID)
              throws CacheException

invalidates all entries that are dependent on this thing. Note that this is potentially more expensive than invalidateByKey

Parameters:

thingID - dependency

Throws:

CacheException - on DB error

invalidateByDepKey

int invalidateByDepKey(IThingID thingID,
                       ICacheKey key,
                       int invalFlags)
                throws CacheException

generates a list of entries to invalidate based on the thingID, then filters that list via cache key. Use ex. would be invalidating only 1 user's affected entries.

Throws:

CacheException
