public class ClassMetaData
extends Extensions
implements Comparable, SourceTracker, MetaDataContext, MetaDataModes, Commentable

Contains metadata about a persistent type. This metadata is available both at enhancement time and runtime. Note that this class employs aggressive caching, and therefore it is important to finalize the configuration of field metadatas before invoking methods that depend on that configuration, such as getPrimaryKeyFields().
