com.avaje.ebeaninternal.server.transaction.DefaultPersistenceContext
Default implementation of PersistenceContext.
Ensures only one instance of a bean is used according to its type and unique id.

PersistenceContext lives on a Transaction and as such is expected to only have a single thread accessing it at a time. This is not expected to be used concurrently.

Duplicate beans are ones having the same type and unique id value. These are considered duplicates and replaced by the bean instance that was already loaded into the PersistanceContext.

  /**
   * For a bean built from the cache this sets up its persistence context for future lazy loading etc.
   */
  private void setupContext(Object bean, SpiQuery<T> query, PersistenceContext context) {
    if (context == null) {
      context = new DefaultPersistenceContext();
    }


    // Not using a loadContext for beans coming out of L2 cache
    // so that means no batch lazy loading for these beans
    EntityBean entityBean = (EntityBean)bean;
