Interface FemSqltypedElement

public interface FemSqltypedElement

This interface belongs in the UML model, but can't live there due to metamodel problems. That's the short story.

You want the unabridged version? CWM declares a number of important attributes on CwmColumn, but the same attributes are needed on other classes such as FemRoutineParameter, and they aren't present on the base class CwmSqlparameter. Validation code would like to be able to handle any kind of SQL-typed object uniformly, so a common interface is required. FemRoutineParameter can't inherit from CwmColumn (that kludgy approach leads to strange MDR multiple-inheritance anomalies). And MDR doesn't support generation of operations, so we can't declare a UML interface with abstract methods.

So, we define this interface outside the model and use proxies to implement it; see FarragoCatalogUtil.toFemSqltypedElement(net.sf.farrago.fem.sql2003.FemAbstractTypedElement). In the model, we define a placeholder interface FemAbstractTypedElement.
