Declaration and definition

What is translated > Routines > Declaration and definition

Routines may be declared first in the interface part of a unit and defined later in the implementation part. If a routine is the member of a class, the declaration always has to be separated from the definition.

interface

type

  TFoo = class

  private

    procedure foo;

  end;

  procedure foo;

implementation

procedure TFoo.foo;

begin

  ...

end;

procedure foo;

begin

  ...

end;

In C# this difference doesn't exist, there is only one place for a routine.

public class TFoo : TObject

{

  private void foo()

  {

    ...

  }

  public TFoo() {}

};

public class ...Class

{

  public static void foo()

  {

    ...

  }

} // ...Class

Member routines are written inside of the class definition and free routines become public static members of the extra class which is created for each unit.
