Informix Error -4125: Not defined/declared as a member in the class hierarchy "name".

Reasons / Common Causes

-4125 fires when an element is referenced as a member of a class hierarchy but is either not declared at all, or declared without being defined, anywhere in that hierarchy — per the official guidance, both cases produce this error.

1. The element is not declared anywhere in the named class hierarchy, per the official guidance — the first named case.
2. The element is declared but never defined, per the official guidance — the second named case.

Solutions / Resolution

1. Check the spelling of the member name, and confirm it's both declared and defined somewhere in the class hierarchy.

Examples

A member declared but not defined

CLASS Order
  FUNCTION save() RETURNING INTEGER
  -- no matching FUNCTION save() ... END FUNCTION definition anywhere
END CLASS

Corrected

CLASS Order
  FUNCTION save() RETURNING INTEGER
    RETURN 0
  END FUNCTION
END CLASS

Diagnostic Checks

1. Check the class hierarchy for both a declaration and a matching definition of the referenced member.
