[hibernate-dev] SchemaManagementTool / Exportable

[Steve Ebersole]

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.
