6.2.1- The Software Telephone Object

The Software Telephone Object

So now we are shifting gears here from describing the real-world telephone as an object to describing a software telephoneobject. This is an example of representation. The properties of the telephone object are:

As you can see, we have used the same names that we usedwhen discussing the physical telephone object. The methods of the telephone object are the same as well. In this case,the methods that have parameters will have the same parameters as well:

Finally – as you will expect by now – events that theobject will support are the same events that are supported by the physicaltelephone object:

Now that we have defined the interfaces of our telephone object, we can take a look at some codeexamples that will show you how to use these interfaces. For these examples, wewill be using VBScript, which is the language that is being used throughout thebook. Since there are three types of interfaces, we will look at three codesamples – one for each type.
