DTO (Data Transfer Objects)

A Data Transfer Object, or DTO is a design pattern for a very specific type of object that is used to transfer data between different parts of your application.

A DTO is just for temporarily storing information whilst it is in transit. Therefor a DTO has limited behaviour, only that of storing, retrieving, validating, and internal consistency checking of its own data. They should have no responsibility in terms of security, transaction, and business logic. This de-coupling of storage and business logic will enable us to use the same DTO in different contexts.

DTOs come in two different types: generic collections, or custom objects.

Generic Collections

Generic collections, eg. Dictionaries or Arrays, are advantageous in that you only require a single DTO for all your data transfer needs. The main disadvantage is that the client has to access fields either by position index (in the case of Arrays), or by key (in the case of Dictionaries). A further problem is that as the type of objects in a collection is unknown. In a future revision of Actionscript Arrays will be typed, which will only allow collections to store data of one type. This can lead to items being stored as a generic Object type, which can lead to subtle but fatal coding errors that cannot be detected at compile time.

The creation of a dynamic generic objects can be costly as Flash doesn’t know how much memory to allocate. By typing all your variables, Flash can then allocate the necessary memory for those variables and no more. This avoids the creation of a Hash Table and will therefor decrease memory consumption and increase performance.

Custom Objects

Creating a custom class for your DTOs provides strictly typed objects which allow for compile-time checking and support code editing features like FDTs “code assist” feature (ctrl + space). The only drawback is the creation of a large amount of DTOs that might be required for a large application.

Fields contained within a custom DTO should be of primitive/simple types eg. strings, booleans, etc. or arrays of those, and it may even contain other DTOs. As DTOs are meant to be temporary objects for transferring data, their fields should be immutable (read-only). Although this can be particularly difficult to achieve under certain circumstances.

1. package ch.forea.exampleDTO {
2. public class CardDTO{
3. private var _name:String;
4. private var _address:String;
5. private var _phone:String;
7. public function CardDTO(name:String, address:String, phone:String){
8. _name = name;
9. _address = address;
10. _phone = phone;
11. }
13. public function get name():String{
14. return _name;
15. }
16. public function get address():String{
17. return _address;
18. }
19. public function get phone():String{
20. return _phone;
21. }
22. }
23. }

The purpose of all this is to package all required information in to one package, therefor transferring everything in one call rather than multiple calls. This method can be advantageous if the call is to a remote system, as any further calls to the DTO are made locally to the client.

ApplicationDomain class

Using the ApplicationDomain class

The purpose of the ApplicationDomain class is to store a table of ActionScript 3.0 definitions. All code in a SWF file is defined to exist in an application domain. You use application domains to partition classes that are in the same security domain. This allows multiple definitions of the same class to exist and also lets children reuse parent definitions.

You can use application domains when loading an external SWF file written in ActionScript 3.0 using the Loader class API. (Note that you cannot use application domains when loading an image or SWF file written in ActionScript 1.0 or ActionScript 2.0.) All ActionScript 3.0 definitions contained in the loaded class are stored in the application domain. When loading the SWF file, you can specify that the file be included in the same application domain as that of the Loader object, by setting the applicationDomain parameter of the LoaderContext object to ApplicationDomain.currentDomain. By putting the loaded SWF file in the same application domain, you can access its classes directly. This can be useful if you are loading a SWF file that contains embedded media, which you can access via their associated class names, or if you want to access the loaded SWF file's methods, as shown in the following example:

package {    

import flash.display.Loader;   

import flash.display.Sprite;  

 import flash.events.*;   

import flash.net.URLRequest;  

 import flash.system.ApplicationDomain;

   import flash.system.LoaderContext;  

  public class ApplicationDomainExample extends Sprite     {

       private var ldr:Loader;       

public function ApplicationDomainExample()         {

           ldr = new Loader();            

var req:URLRequest = new URLRequest("Greeter.swf");            

var ldrContext:LoaderContext = new LoaderContext(false,

ApplicationDomain.currentDomain);            

ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);

 ldr.load(req, ldrContext);             }       

private function completeHandler(event:Event):void         {  

        ApplicationDomain.currentDomain.getDefinition("Greeter");  

         var myGreeter:Greeter = Greeter(event.target.content);   

        var message:String = myGreeter.welcome("Tommy");       

    trace(message); // Hello, Tommy         }     } }









Other things to keep in mind when you work with application domains include

the following:
 
All code in a SWF file is defined to exist in an application domain.

The  current domain is where your main application runs.

The system  domain contains all application domains, including the current

domain,  which means that it contains all Flash Player classes.

All application domains, except the system domain, have an associated parent

domain. The parent domain for your main application's application domain is

the  system domain. Loaded classes are defined only when their parent doesn't

already  define them. You cannot override a loaded class definition with

a newer  definition. 

REST parameter

ActionScript 3.0 introduces a new parameter declaration called the ... (rest) parameter. This parameter allows you to specify an array parameter that accepts any number of comma- delimited arguments.

function getItems(...rest):void
{
 // ... logic goes here
}

Notice that the only parameter the getItems method is ...rest, this is a rest parameter. When creating a rest parameter you should keep the following things in mind:

• Rest parameters are untyped. It is up to you to validate any special type requirements as you loop through the rest parameter array.
• Rest parameters must be at the end of a method's parameters.
• The rest parameters must have ... in front of it, but the variable name can be anything.

When you want to retrieve values out of a rest parameter you simply iterate (loop) through them like you would any other array. Here is an example:

 
function getItems(...items):void
{
 var total:int = items.length;
 for( var i:int = 0; i < total; i++)
 {
   trace("Look up item", items[i]);
  }
}

getItems("testA","testB","testC", 10);

When we call the method we can pass in any number of items as
long as they are separated by a comma. Back in the getItems method we get the
total from the rest parameter just like we would an array.

Skinnign FLV Component

Skinning FLV Playback Custom UI components individually

The FLV Playback Custom UI components allow you to customize the appearance of the FLVPlayback controls within your FLA file and allow you to see the results when you preview your web page. These components are not designed to be scaled, however. You should edit a movie clip and its contents to be a specific size. For this reason, it is generally best to have the FLVPlayback component on the Stage at the desired size, with the scaleMode set to exactFit.

To begin, simply drag the FLV Playback Custom UI components that you want from the Components panel, place them where you want them on the Stage and give them instance names.

These components can work without any ActionScript. If you put them on the same timeline and frame as the FLVPlayback component and there is no skin set in the component, the FLVPlayback component will connect automatically to them. If you have multiple FLVPlayback components on Stage, or if the custom control and the FLVPlayback instance are not on the same Timeline, then Action is needed.

After your components are on the Stage, you edit them as you would any other symbol. After you open the components, you can see that each one is set up a little differently from the others.

Choosing Between Timer and Event.ENTER_FRAME

Choosing Between Timer and Event.ENTER_FRAME

As we’ve just seen, the Timer class and the Event.ENTER_FRAME event can both be used
to produce animation. So which one is right for your family? Here are the major factors
to consider:

1. Frame rate is subject to change

When a .swf file is loaded by another application, the frame rate of that application
might be vastly different than the .swf file’s designated frame rate, potentially
causing the .swf ’s animations to play too quickly or too slowly. The loaded
.swf file can, of course, set the frame rate, but that change in frame rate might
cause undesirable playback behavior in the parent application. The Timer class
offers some frame-rate independence (subject to the limitations discussed in the
earlier section “Frame Rate’s Effect on Timer”).

2. Using many Timer objects requires more memory

In decentralized animation management architectures, using a separate Timer to
control the animation of each object requires more memory than would be
required by the analogous Event.ENTER_FRAME implementation.

3. Using many Timer objects can cause excessive screen update requests

In decentralized animation management architectures, using a separate Timer in
conjunction with updateAfterEvent( ) to control the animation of each object
leads to multiple independent requests for screen updates, possibly leading to
performance problems.

Adobe Flash Collaboration Service aka Cocomo

AFCS (Adobe Flash Collaboration Service) previously known as 'Cocomo' is a Platform as a Service (PaaS) that that allows Flex developers to address a class of applications known as collaborative applications.

Collaborative Applications have progressed from a nice cool thing into serious applications. Almost all of us would have participated in an online chat or a web meeting, which allows a group of users to chat, share files, do screen sharing, take polls, ask questions and receive answers, etc. AFCS aims to lower the barrier to entry for developers to bring such collaborative features into their applications.

A developer would have general questions like:

• Why do we need a set of components to enable collaborative features in my application?
• It should not be that complex to build a collaborative application, right? Isn't chat and sharing some files the maximum that I would want?
• …and many more.

Well, building collaborative applications is not as simple as it sound. If you wish to build a collaborative application - you will need to consider the following in your application:

• Handle Audio, Video and all other forms of transcoding data
• Ensure that your application can scale to a large number of users.
• Enable shared state in your application and ensure that multiple users are co-coordinated with each other so maintain data integrity
• Reuse commonly used components like chat, notes, whiteboard, etc so that you can build the applications quickly and not reinvent the wheel.
• Handle User Management and Permissions

Flash Test paper1

Question 1

Step1

Create an XML file having information of 5 images.

Step 2

Load each node image of the xml file on the stage in a movie clip in such a manner that image will load at the center of the stage means there will not be any effect of resizing of the stage dimension.

Step 3

Set alpha 0 to 100 when each image appears. Provide buttons (Next, Previous) for navigation.

Step 4

Display height and width of each image in a text box when image loads.

Question 2

Create two buttons label (Circle, Rectangle) on clicking of each button draw shape accordingly on mouse movement

Question 3

Create a form in flash having information field say Name, Address, and Age.

User can enter information in these fields accordingly. If user closes this SFW file and again it open last field’s value should populated automatically.

Flash Test.. Try it

Drop circles on screen

Create a SWF that:

1. Starts with a blank screen.
2. When the user clicks anywhere on the movieclip, a small circle appears (around 25px in diameter) at the clicked position.
3. Each time the user clicks on the movieclip, another circle is visible.

Drag ’n Drop

Create an SWF that:

1. Has a single square present, 50x50 pixels in size.
2. Allows you to click and drag the square anywhere on screen.

Intermediate problems

MouseOver

Create an SWF with:

1. Three rectangles shown on screen, filled with Red, Blue and Green colours.
2. A textfield placed below the rectangles.
3. Whenever you move your mouse over a rectangle, that rectangle’s colour is displayed in the textfield.

Drawing

Create a SWF that:

1. Allows you to click-and-draw lines on-screen. Just straight lines, by clicking anywhere, dragging your mouse cursor, and releasing it. The line should start from the point where you clicked on and end at the point where you release the mouse cursor.
2. The colour of the lines you want to draw next can be changes using a ColorPicker.
3. Has a ‘Clear’ button. On click of this button, any lines on screen are removed, and you again have a blank slate to work with.

Advanced problems

External Image Viewer

Create an SWF that:

1. Has a textfield where the user can input an image URL.
2. A button labelled ‘show image’, on click of which the image referenced by the URL is loaded in an UILoader present on screen.
3. The user can pan the image (either using mouse drag or scrollbars) if it is too large to view.

Folder Creation-- Flash-- Not Possible

W can not make the folders or write any thing on our local using flash except for the shared object..

We can use third party tools like Zinc for that..

We can also use AIR for making that but these all are for desktop application.

web application cant do it ..

in Zinc we use it like this


working_folderLis.click = function (eventObject)
{
myfolder_br = mdm.Dialogs.BrowseFolder.show();
if (myfolder_br != "false")
{
working_folder.text = myfolder_br;
modules_combo.removeAll();
pageList.removeAll();
blankMc.unloadMovie();
refreshTracker();
refreshGlobals();
var _loc2 = mdm.FileSystem.fileExists(working_folder.text + "\\index_tracker.txt");
if (!_loc2)
{
mdm.FileSystem.copyFolder(mdm.Application.path + "\\att_common", working_folder.text);
mdm.FileSystem.copyFolder(mdm.Application.path + "\\metadata", working_folder.text);
for (var _loc1 = 0; _loc1 <>
{
mdm.FileSystem.copyFolder(mdm.Application.path + "\\sco_elements\\" + sco_folders[_loc1], working_folder.text);
} // end of for
for (var _loc1 = 0; _loc1 <>
{
mdm.FileSystem.makeFolder(working_folder.text + "\\" + empty_folders[_loc1]);
} // end of for
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\includes");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\images");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\html");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\css");
mdm.FileSystem.makeFolder(working_folder.text + "\\att_common\\audio");
initTracker();
disableBtns(false);
}
else
{
refreshTracker();
disableBtns(true);
} // end if
} // end else if
};
working_folder_btn.addEventListener("click", working_folderLis);

DUPLICATE CLIP IN AS3

Firstly we need to create duplicate display object

duplicateDisplayObject.as

package {

import flash.display.DisplayObject;
import flash.geom.Rectangle;
import flash.system.Capabilities; // version check for scale9Grid bug

/**
* duplicateDisplayObject
* creates a duplicate of the DisplayObject passed.
* similar to duplicateMovieClip in AVM1. If using Flash 9, make sure
* you export for ActionScript the symbol you are duplicating
* @param target the display object to duplicate
* @param autoAdd if true, adds the duplicate to the display list
* in which target was located
* @return a duplicate instance of target
*/
public function duplicateDisplayObject(target:DisplayObject, autoAdd:Boolean = false):DisplayObject {
var targetClass:Class = Object(target).constructor;
var duplicate:DisplayObject = new targetClass() as DisplayObject;

// add to target parent's display list
// if autoAdd was provided as true
if (autoAdd && target.parent) {
target.parent.addChild(duplicate);
}
return duplicate;
}
}

doubleRed.as class

package {
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Graphics;
import flash.display.Sprite;
import flash.geom.Rectangle;
import flash.geom.ColorTransform;
import flash.display.MovieClip;


public class doubleRed extends Sprite{
public function doubleRed()
{
graphics.beginFill(0x00ff00);
graphics.drawCircle(50,50,15);
graphics.endFill();
}
}
}


After it we just need to make a document class and its done!!!!!!!!!!!!

Need of Interfaces

Interfaces are used to encode similarities which classes of various types share, but do not necessarily constitute a class relationship. For instance, a human and a parrot can both whistle. However, it would not make sense to represent Humans and Parrots as subclasses of a Whistler class. Rather they would most likely be subclasses of an Animal class (likely with intermediate classes), but both would implement the Whistler interface.

Another use of interfaces is being able to use an object without knowing its type of class, but rather only that it implements a certain interface. For instance, if one were annoyed by a whistling noise, one may not know whether it is a human or a parrot, because all that could be determined is that a whistler is whistling. In a more practical example, a sorting algorithm may expect an object of type Comparable. Thus, it knows that the object's type can somehow be sorted, but it is irrelevant what the type of the object is. The call whistler.whistle() will call the implemented method whistle of object whistler no matter what class it has, provided it implements Whistler.
