Example 1 with SingularAttributeProxyImpl

use of org.eclipse.persistence.internal.jpa.metamodel.proxy.SingularAttributeProxyImpl in project eclipselink by eclipse-ee4j.

the class EntityManagerSetupImpl method preInitializeCanonicalMetamodel.

/**
 * INTERNAL:
 * First phase of canonical metamodel initialization.  For each class the metamodel is aware of, check
 * for a canonical metamodel class and initialize each attribute in it with a proxy that can cause the
 * rest of the metamodel population.  Attributes are found reflectively rather than through the metamodel
 * to avoid having to further initialize the metamodel.
