Examples with Junction org.hibernate.criterion.Junction used on opensource projects

Example 1 with Junction

use of org.hibernate.criterion.Junction in project candlepin by candlepin.

the class PoolCurator method lookupOversubscribedBySubscriptionIds.

/**
 * Attempts to find pools which are over subscribed after the creation or
 * modification of the given entitlement. To do this we search for only the
 * pools related to the subscription ID which could have changed, the two
 * cases where this can happen are:
 * 1. Bonus pool (not derived from any entitlement) after a bind. (in cases
 * such as exporting to downstream)
 * 2. A derived pool whose source entitlement just had it's quantity
 * reduced.
 * This has to be done carefully to avoid potential performance problems
 * with virt_bonus on-site subscriptions where one pool is created per
 * physical entitlement.
 *
 * @param ownerId Owner - The owner of the entitlements being passed in. Scoping
 *        this to a single owner prevents performance problems in large datasets.
 * @param subIdMap Map where key is Subscription ID of the pool, and value
 *        is the Entitlement just created or modified.
 * @return Pools with too many entitlements for their new quantity.
