Examples of org.datanucleus.metadata.AbstractClassMetaData

org.datanucleus.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.
