bool dbField::fieldIsIndexed (   )  const [virtual, inherited]

bool dbField::fieldIsJoinKey (   )  const [inherited]

Checks if any relationships in field's table use field as join key. Relatively expensive because it's iterating over all fields but all the function calls below are inline queries so will compile down well in release mode. WARNING Doesn't fan out - if any other tables use this field as a join key then they are doing really weird stuff and the application programmer must add their own checks. This feature originally added to support OOF_repEditSetupVisitor::VisitViewBandBody
