A method and system are provided for runtime dynamic binding. The system includes a processor for executing computer-readable instructions. The system includes a computer-readable medium for storing an object definition in communications with the processor. The system includes a user object instantiated from the object definition, the object definition including a programmer-defined lookup method and a programmer-defined binding method. The programmer-defined lookup method dynamically searches and retrieves a requested functionality. The programmer-defined binding method dynamically binds the requested functionality at runtime for execution without a system restart.
