Example 1 with MapKeyMapping

use of org.eclipse.persistence.mappings.foundation.MapKeyMapping in project eclipselink by eclipse-ee4j.

the class MapAttributeImpl method getOwningPKTypeWhenMapKeyAnnotationMissingOrDefaulted.

/**
 * INTERNAL:
 * Default to the PK of the owning descriptor when no MapKey or MapKey:name attribute is specified.
 * Prerequisites: policy on the mapping is of type MappedKeyMapPolicy

    Class<?> javaClass = null;
    ;
    MapKeyMapping mapKeyMapping = policy.getKeyMapping();
    ClassDescriptor descriptor = ((DatabaseMapping) mapKeyMapping).getDescriptor();
    // If the reference descriptor is null then we are on a direct mapping
