Class MapKeyMetadata

java.lang.Object

org.eclipse.persistence.internal.jpa.metadata.ORMetadata

org.eclipse.persistence.internal.jpa.metadata.mappings.MapKeyMetadata

public class MapKeyMetadata
extends ORMetadata

Object to hold onto map key metadata. Key notes: - any metadata mapped from XML to this class must be compared in the equals method. - when loading from annotations, the constructor accepts the metadata accessor this metadata was loaded from. Used it to look up any 'companion' annotation needed for processing. - methods should be preserved in alphabetical order.

EclipseLink 2.0
