Example 2 with Status

use of org.hibernate.engine.spi.Status in project hibernate-orm by hibernate.

the class AbstractFlushingEventListener method flushEntities.

    // 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.

Example 3 with Status

use of org.hibernate.engine.spi.Status in project hibernate-orm by hibernate.

Example 4 with Status

use of org.hibernate.engine.spi.Status in project hibernate-orm by hibernate.
