Class EntityListenerMetadata

  • All Implemented Interfaces:
    Cloneable
    Direct Known Subclasses:
    EntityClassListenerMetadata
    public class EntityListenerMetadata
extends ORMetadata
implements Cloneable
    A MetadataEntityListener and is placed on the owning entity's descriptor. Callback methods from an EntityListener require a signature on the method. Namely, they must have an Object parameter. 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.
