Examples of org.jpox.metadata.AbstractClassMetaData

org.jpox.metadata.AbstractClassMetaData
Abstract representation of the MetaData of a class/interface. Has a parent PackageMetaData that can contain the metadata for several classes/interfaces. Is extended by ClassMetaData and InterfaceMetaData. Of the things that it contains the main one are the "members" which are the MetaData for all fields and properties that are persistable. @since 1.1 @version $Revision: 1.98 $
