  ariba.ui.meta.persistence.Loader

public class Loader
extends java.lang.Object

CSV Data loader. Enable loading data into a cluster of classes from a group of inner-dependent load files. Load file resources identify their classes and fields through naming convention. E.g.: loads/ariba.appcore.User.csv -- Load for User class name, email, manager.name, ... -- Column names denote field names. Relationship field dotted paths identify join key loads/ariba.appore.User-memberOf.csv -- Load of User -> Group many-to-many relationship ("-memberOf" denotes toMany field being loaded) name, memberOf.name -- unprefixed names are lookup keys for the root class, prefixed names are lookup keys for the destination Dependent load handling - Loads are automatically ordered based on class dependencies - in one-to-many, one goes first - Upserts are used, so missing objects on foreign key references are created and then filled in later Data Formatting - parsing of data fields is handled using *formatters* looked up via metaui
