Method and system for extending scripting languages

A system for extending a script language in a runtime environment of the system to support an application, the runtime environment having a script language interpreter, the system comprising:

• a processor coupled to memory and an interface to a network, and adapted to:
• subclass a predetermined object defined by the script language to create a subclassed object, the predetermined object having an original method, the subclassed object having a respective replacement method for supporting the application;
• dynamically register a symbol corresponding to the subclassed object;
• detect the subclassed object in the application with the script language interpreter;
• and,
• execute the replacement method with the script language interpreter.

A computer program product having a computer readable medium tangibly embodying computer executable code for directing a data processing system to extend a script language in a runtime environment of the data processing system to support an application, the runtime environment having a script language interpreter, the computer program product comprising:

• code for subclassing a predetermined object defined by the script language to create a subclassed object, the predetermined object having an original method, the subclassed object having a respective replacement method for supporting the application;
• code for dynamically registering a symbol corresponding to the subclassed object;
• code for detecting the subclassed object in the application with the script language interpreter;
• and,
• code for executing the replacement method with the script language interpreter.
