Re: [hibernate-dev] SchemaManagementTool / Exportable
What is everyones thoughts on having Exporter contain methods for
create, drop and alter scenarios versus getting Exporter per each of
those actions?
interface Exporter<T extends Exportable> {
public String[] sqlCreateStrings(T exportable, Dialect dialect);
public String[] sqlDropStrings(T exportable, Dialect dialect);
public String[] sqlMigrationStrings(T exportable, Dialect dialect);
}
+
Exporter<Table> gerTableExporter() {
return ...;
}
versus
interface Exporter<T extends Exportable> {
public String[] sqlExportStrings(T exportable, Dialect dialect);
}
Exporter<Table> gerTableExporter(Exporter.Action typeOrExport) {
return ...;
}
I think the first is simpler for our use cases, but I can see how the
seconds might be simpler for custom ones.
