◆ setNotificationTimestampsForUser()

WatchedItemStore::setNotificationTimestampsForUser ( UserIdentity  $user,
  $timestamp,
array  $targets = [] 
)

Set the "last viewed" timestamps for certain titles on a user's watchlist.

If the $targets parameter is omitted or set to [], this method simply wraps resetAllNotificationTimestampsForUser(), and in that case you should instead call that method directly; support for omitting $targets is for backwards compatibility.

If $targets is omitted or set to [], timestamps will be updated for every title on the user's watchlist, and this will be done through a DeferredUpdate. If $targets is a non-empty array, only the specified titles will be updated, and this will be done immediately (not deferred).

Since
1.27
Parameters
UserIdentity$user
string | int$timestampValue to set the "last viewed" timestamp to (null to clear)
LinkTarget[]$targetsTitles to set the timestamp for; [] means the entire watchlist
Returns
bool

Looks like $cacheIndex[Namespace ID][Target DB Key][User Id] => 'key' The index is needed so that on mass changes all relevant items can be un-cached.

For example: Clearing a users watchlist of all items or updating notification timestamps for all users watching a single target.
