Example 1 with FlushEntityEventListener

use of org.hibernate.event.spi.FlushEntityEventListener in project hibernate-orm by hibernate.

the class AbstractFlushingEventListener method flushEntities.

/**
 * 1. detect any dirty entities
 * 2. schedule any entity updates
 * 3. search out any reachable collections
 */

    // Among other things, updateReachables() will recursively load all
    // collections that are moving roles. This might cause entities to
    // be loaded.
    // So this needs to be safe from concurrent modification problems.
