Transfer Configuration File

This configuration file defines the packages and objects that are created and produced by Transfer.

The xml schema file can be found at: /transfer/resources/xsd/transfer.xsd.

It is highly recommended that when creating a new transfer xml file, you validate your xml against this xml schema.

Items in italics denoted an element attribute.

        This creates several methods on the parent TransferObject, dependent on the set collection type. Details on all these methods can be found at Generated Methods.
        TransferObjects can have multiple manytomany declarations.

        You can only have one manytomany definition for each linking table. Bi-directional manytomany is not yet supported.
