the class InterfaceMetaData method populate.

/**
 * Method to provide the details of the class being represented by this
 * MetaData. This can be used to firstly provide defaults for attributes
 * that aren't specified in the MetaData, and secondly to report any errors
 * with attributes that have been specified that are inconsistent with the
 * class being represented.
 * <P>
 * One possible use of this method would be to take a basic ClassMetaData
 * for a class and call this, passing in the users class. This would then
 * add AbstractMemberMetaData for all fields in this class providing defaults for all of these.
 *
 * @param clr ClassLoaderResolver to use in loading any classes
 * @param primary the primary ClassLoader to use (or null)
