Field Summary

public  GenerationType	SEQUENCE	Indicates that the persistence provider must assign primary keys for the entity using database sequence column.
public  GenerationType	IDENTITY	Indicates that the persistence provider must assign primary keys for the entity using database identity column.
public  GenerationType	AUTO	Indicates that the persistence provider should pick an appropriate strategy for the particular database.

A vendor may provide documentation on how to create such resources in the event that it does not support schema generation or cannot create the schema resource at runtime.
