Informix Error -4132

-4132 Incorrect base class name in base clause.

The program has declared a base class and has declared another class as DERIVED FROM that base class. In the definition of the constructor for the derived class, a base constructor clause specifies a call to a function that is NOT the base class constructor. Suppose a derived class is called "bread" and its base class is called "food"; if the constructor for loaf should have a definition that begins FUNCTION bread::bread(args1):food(args1). If it begins FUNCTION bread::bread(args1):beverage(args1), the error message appears.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4132 fires when a derived class's constructor base clause names a function that isn't the actual base class's constructor — per the official guidance, if a class bread derives from food, its constructor must call food(...), not some other class like beverage(...).

A constructor's base clause calling a function that isn't the true base class's constructor, per the official guidance — the direct, only cause.

Solutions / Resolution

Change the base clause to call the actual base class's constructor.

Examples

An incorrect base clause

CLASS bread DERIVED FROM food
  FUNCTION bread(args1) : beverage(args1)
    -- -4132: bread derives from food, not beverage
  END FUNCTION
END CLASS

Corrected

CLASS bread DERIVED FROM food
  FUNCTION bread(args1) : food(args1)
    ...
  END FUNCTION
END CLASS

Diagnostic Checks

Check the constructor's base clause against the class's actual DERIVED FROM base class, and correct the called function if they don't match.

A constructor's base clause calls a function that isn't the actual base class's constructor — correct it to match the DERIVED FROM class.
