Objective

This example implements a class to represent an optical multiplex card. These cards

typically have several input ports and an output port. The MuxCard class represents the

ports by the port names and port data rates. The output rate of a multiplex card is the

sum of the input port data rates.

Why Derive from int32

The MuxCard class derives from the int32 class because 32–bit integers represent the

input port data rates. The MuxCard class inherits the methods of the int32 class, which

simplifies the implementation of this subclass. For example, numeric array indexing and

arithmetic operations work on MuxCard objects because the class inherits these

operations from the int32 class.

Implementation

Here is the definition of the MuxCard class. Notice that the input port rates initialize the

int32 portion of class.
