_next
GB_METHOD ( "_next" , Return Type , MyClass_next , NULL )
GB_STATIC_METHOD ( "_next" , Return Type , MyClass_next , NULL )
The
_next method is called when the Gambas program use the
FOR EACH ...
IN
instruction to enumerate the object.
The method takes no parameters, and may return an enumerated data.
The method can be static. Then, the class will be enumerable, not the object.
This method can return nothing. Then, you will enumerate the object with a
FOR EACH
instruction, without the
IN part.
Inside the
_next method implementation, you will use some specific Gambas Programming
Interface functions. See
Enumeration Management for more information.
