Class KittyDevDropCreateMigrator

java.lang.Object

net.akaish.kitty.orm.dumputils.migrations.KittyORMVersionMigrator

net.akaish.kitty.orm.dumputils.migrations.KittyDevDropCreateMigrator

public class KittyDevDropCreateMigrator
extends KittyORMVersionMigrator

Class for processing migrations from different versions of schema to current without full sequences.
This migrator should be used only in development purposes because it can't handle old existing indexes and tables (and whatever)
that may exist in old schema version but were deprecated in current. This migrator just drops all tables and indexes with same names that are used
in current version creates them. For example old schema contained tables "goods" "clients" and "contacts" but in new version you decided to get rid
of "contacts" table. Your current schema would have only two tables, "goods" and "clients". So they would be dropped with IF EXISTS flag and then created.
However "contacts" table and all associated data would stay cause this migrator doesn't now anything about it (it works only with current schema).
If you want pass already existing migration script sequence you should pass an instance of LinkedList filled with instances of KittySQLiteQuery as [1] of migrationsParameters.
In last case you can manually drop ALL schema and than apply creation script generated with CreateDropHelper.generateCreationScript(KittyDatabaseConfiguration). Created by akaish on 14.06.2018.
