Yes sir!
There was an old object in TurPascal that was called `Object`!
In Turbo Pascal, the Object type is a base object type that does not require explicit memory management like classes.You can create and use objects of this type without the need to explicitly free them.
Here's a sample code demonstrating the usage of the Object type in Turbo Pascal:
The Initialize method sets the value of `Value` based on the provided parameter. The `Display` method prints the value of `Value` to the console.
Inside the `begin` and `end` block, we declare a variable `MyObject` of type `TMyObject`. We then call the `Initialize` method on `MyObject` to set its value to 42 and call the `Display` method to print the value to the console.
Since `TMyObject` is an object, it does not require explicit memory management. The object is automatically allocated and deallocated when it goes out of scope.
Note that the `object` type in Turbo Pascal does not support inheritance or virtual methods like classes do. It is a simpler construct primarily used for encapsulating data and methods within a single unit of code.
program ObjectDemo;
type
TMyObject = object
Value: Integer;
procedure Initialize(AValue: Integer);
procedure Display;
end;
procedure TMyObject.Initialize(AValue: Integer);
begin
Value := AValue;
end;
procedure TMyObject.Display;
begin
Writeln('Value:', Value);
end;
var
MyObject: TMyObject;
begin
MyObject.Initialize(42);
MyObject.Display;
// No need to free the object explicitly
Readln;
end.
In this code, we define a type `TMyObject` using the `object` keyword. It has a member variable `Value` of type `Integer` and two methods: `Initialize` and `Display`.
The Initialize method sets the value of `Value` based on the provided parameter. The `Display` method prints the value of `Value` to the console.
Inside the `begin` and `end` block, we declare a variable `MyObject` of type `TMyObject`. We then call the `Initialize` method on `MyObject` to set its value to 42 and call the `Display` method to print the value to the console.
Since `TMyObject` is an object, it does not require explicit memory management. The object is automatically allocated and deallocated when it goes out of scope.
Note that the `object` type in Turbo Pascal does not support inheritance or virtual methods like classes do. It is a simpler construct primarily used for encapsulating data and methods within a single unit of code.
Is it available yet in modern Delphi?
Yes, there is, in the matter of backward compatibility.
