Method DataObject():noMethod() Foundation

Handles calls to undefined methods.

:noMethod() -> NIL

Execution of an undefined method always returns NIL.


The method :noMethod() is executed whenever an undefined method is called. The implementation of :noMethod() in the DataObject class always returns the value NIL.

In order to dynamically add a method to a DataObject instance, the method :defineMethod() must be used. Once a method is defined using :defineMethod(), calls to the new method no longer cause :noMethod() to be executed. Consequently, overriding :noMethod() in a derived class is not required for adding methods to DataObject instances.
