> Various user-defined objects can be created which are bound to Java methods
> or classes via "external name" clauses. It's easy to mis-phrase the Java
> class name in the "external name" clause if the class is a static nested
> class. The affected objects include:
> o Functions
> o Procedures
> o Types
> o Aggregates
> Consider the following class:
> public class TestFuncs
> {
> public static final class Foo
> {
> public static double pow( double base, double power ) { return
> Math.pow( base, power ); }
> }
> }
> If the pow method is bound to a user-defined function via a CREATE FUNCTION
> command, its external name should be TestFuncs$Foo.pow, NOT TestFuncs.Foo.pow.
> We should add a section to the Reference Manual clarifying how to phrase the
> external name if it includes a reference to a static nested class. The
> detailed sections for the various user-defined objects can then refer to this
> new section.
