Each time the method is called, it generates the next number (or adds some value) to the property and returns the new value. Common uses for a protected property, with an exposed Get() method, like this include handling serial (sequential values), or accumulator (running total) values. ![]() ![]() Of course the method could do much more than simply return the value. Other members of the xBase language family include Clipper and Recital (database). ![]() The method is defined in the class that defines the property and so it can see the property, and return its value to the caller even though the caller cannot actually see the property. Visual FoxPro originated as a member of the class of languages commonly referred to as 'xBase' languages, which have syntax based on the dBase programming language. ![]() Conventional range means a class of kitchen ranges and ovens which is a. However, when we call the GetProperty() method – which is itself public remember - there is no problem. A convection oven, meanwhile, has built-in fans that circulate definition. As you can see, by declaring the property protected we get an “Property does not exist” error when we try to access it directly from outside.
