Examples of org.eclipse.persistence.queries.AttributeGroup

org.eclipse.persistence.queries.AttributeGroup
Purpose: An AttributeGroup represents a set of mappings and nested AttributeGroups for relationship mappings for an entity type. Responsibilities:
- Defines which attributes should be fetched from the database within a {@link FetchGroup}.
- Define which relationship attributes should be populated in a resulting entity graph within a {@link LoadGroup}
- Define which attributes should be copied within a {@link CopyGroup}
To reference nested attributes a dot ('.') notation is used to reference related attributes. All attribute names provided are assumed to be correct until processed against the mappings during usage of the group. @see FetchGroup @see LoadGroup @see CopyGroup @author ailitchev @since EclipseLink 2.1
