Constructor (Delphi and Corel Paradox Cross Reference Guide)

General Info: Class Constructor

Constructors are called when you instantiate an object from a class. This is where you can initialize variables and put code you wish executed each time the class is created. When you initially set the member fields and properties of an object, you are initializing the state of the object. The state of an object is the values of all it's member fields and properties at a given time.

Delphi:  "Constructors" constructor In Delphi, use the constructor keyword to signify which method or methods are constructors for a class. It is traditional but not required to use a procedure called Create. In addition to having multiple named constructors, you can overload constructors. Syntax Example: //Interface section. TCyborg = class(TObject) public   constructor Create; end;  Then implement the class constructor in the Implementation section. constructor TCyborg.Create; begin   inherited;  //Call the parent Create method end;  Delphi Constructors (constructor)
