The last language feature I'll discuss in this chapter is the use of class references, which implies the idea of manipulating classes themselves within your code. It returns the class you want to instantiate, leaving instantiating up to you. Class members of a class belong to the type itself, and you do not need to instantiate an object in order to call them. You can design the getApsClass function to take a string parameter, or an int, or anything else you might desire -- it doesn't matter. in C, it took me 1 hour with all the cosmetics (randomly initializing an array or user-provided size and sorting it…).

Abstract methods differ from virtual methods by the base class not providing any implementation. The scripting system supports the DelphiScript language, which is very similar to Embarcadero Delphi™. An abstract method is a class method which won't be implemented but is expected to be implemented by the descendants of the class. The Create constructor is a class method, as opposed to virtually all other methods you'll encounter in Delphi programming, which are object methods. The code basically appears as if the same class had been written as the generic but with T replaced by the given type. #あっ、それからDelphiのバージョンは一応5.

The usual difference between a function and a procedure is that a function can return a value, and a procedure generally will not do so. We further generalize these results to typed lambda calculus with pairs and higher-order functions. To visualize this data, we need a multi-dimensional data structure, that is, a multi-dimensional. It seems to be impossible to define method pointers that point to a method of a class, so that you can later say 'now do your stuff on this instance of the class'.

Our "TCalculator" class implements an interface and that is why it cannot be inherited directly from "TObject", but it needs to be derived from "TInterfacedObject" which is the base class for all Delphi classes that implements interfaces. But even for a wizard, it's always a question whether or not we're usingthe full potential of our abilities. For example TH1::Draw("col") draws a 2-D histogram with cells represented by a box filled with a color CI function of the cell content. The problem is that the GetClass function requires the class to be registered before the function can find it.
