Where are we going?

• Two main projects (2nd half of 2013):– Android support in Delphi– Mobile Development in С++

(April 16 it was announced that, Embarcadero now is a Standard C++ Foundation sponsor - isocpp.org)

• Support other platforms – next stops are

• 2013+ : SmartTV, Car Infotainment, smart home, «smart» watches and other.

25

«Native» and custom styles

26

Gesture support

• Swipe• Tap• Pinch & Zoom• Tap & Hold• Double-Tap

New language features

New Compiler Architecture

Open IR

31

New Language features

• String types• ARC (Automatic Reference Counting)

32

Different String Types

• Pascal short strings (255)• AnsiString (C-o-W, R-C)• + little bit more (UTF8String и RawByteString)• С-like (PChar)• Unicode strings (from 2009), UTF16 (C-o-R, R-C)• COM-compatible (no R-C)

33

One string type

• Unicode-based• Immutable str1[i] := ch• Reference-counted

34

What is the right way?

• TStringBuilder (it is not new …)

• s1, s2, s3 : string;• s1 := ‘Hello’;• s2 := ‘World’;• s3 := s1 + s2;

• sBuilder := TStringBuilder.Create; • sBuilder.Append(s1);• sBuilder.Append(s2);• s3 := sBuilder.ToString;• sBuilder.Free;

35

Immutable

• TStringBuilder (it is not new …)

for I := Low (str1) to High (str1) do if str1 [I] = 'a' then str1 [I] := 'A’;

sBuilder := TStringBuilder.Create;for I := Low (str1) to High (str1) do if str1.Chars [I] = 'a' then sBuilder.Append ('A') else sBuilder.Append (str1.Chars [I]);str1 := sBuilder.ToString;sBuilder.Free;

36

Zero-based strings

• We are familiar with it– Dynamic arrays– List : TList; List.Items[0]– sList: TStringList; sList[]– ListBox1.Items[0]

• $ZEROBASEDSTRINGS

37

Zero-based strings

• No changes in the string.• You can mix it (project, unit, function)• RTL functions are still 1-based• Use TStringHelper

– unit System.SysUtils;– MyString.Length; MyString.ToInteger;– …

38

TStringHelper

• procedure TForm4.Button1Click(Sender: TObject);• var• s1: string;• begin• // apply to a variable• s1 := 'Hello';• if s1.Contains('ll') then• ShowMessage

(s1.Substring(1).Length.ToString);• // apply to a constant• Left := 'Hello'.Length;• // «in chain»• Caption := ClassName.Length.ToString;• end;

39

Automatic Reference Counting

• Memory management• string• Interface variable• Its not a Garbage Collector!• ARC – automatic reference counting

40

Interface

• TMyClass = class(TInterfacedObject, IMyInterface)

• // ...• end;

• IMyInterface = interface(IInterface)• // ...• end;

41

Interface

• procedure TForm1.Button1Click(Sender: TObject);• var• myInterface : IMyInterface;• begin• myInterface := TMyClass.Create;• //...• end;

42

ARC

• ARC by default in LLVM compiler• iOS device and Simulator (Mac)

• procedure TForm1.Button1Click(Sender: TObject);

• var• MyObj: TMySimpleClass;• begin• MyObj := TMySimpleClass.Create;• // ...• end;

43

ARC - release

• procedure TForm1.Button1Click(Sender: TObject);

• var• myObj : TMyClass;• begin• myObj := TMyClass.Create;• // ...• myObj := nil;• // ...• end;

MyObj.DisposeOf;

44

ARC - reference• type• TMyComplexClass = class;•  • TMySimpleClass = class• private• [Weak] FOwnedBy: TMyComplexClass;• public• constructor Create();• destructor Destroy (); override;• procedure DoSomething(bRaise: Boolean = False);• end;•  • TMyComplexClass = class• private• fSimple: TMySimpleClass;• public• constructor Create();• destructor Destroy (); override;• class procedure CreateOnly;• end;
