Embodiments of the invention provide a dictionary, which may be modified by a developer, that provides a mapping of the generation routine to be performed and a pointer or identifier of the generator employed for the specified generation routine. As will be appreciated, embodiments of the invention may employ a dictionary which comprises a plurality of generation routine-code generator identity data pairs. A generator routine may be, for example, associated with the generation of source code associated with a particular object class, fields, methods, method bodies, procedures, comments, subroutines and the like. By modifying a generation routine-code generator identity data pair in a generator dictionary, a developer or user is able to modify the source code (e.g., the structure and/or content of the source) which is ultimately generated by the generator.
