      Description

      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.
