I nailed down this issue. If a class is imported in the timeline, its
super class will be embedded.
// Class definitions:
class Test extends Super {}
class Super {}
// Timeline: _root
import Test;
// Test;
trace(_global['Super']); // Output: [type Function]
trace(_global['Test']); // Output:
It is a very interesting find, Derek. I haven't noticed that.

Then how do you explain my results?
Because some of those classes instantiate other classes (in the UIObject
hierarchy), so those classes are compiled even though you didn't instantiate
the first class. Importing *any* of the MM UI components will instantiate
all kinds of lower-level classe

Hi Derek,
That's really interesting - and goes against everything I'd expect.
Particularly when your other results have kind of proved the opposite
(and I've certainly proved the opposite before with ClassFinder
situations). A couple of other tests might prove illuminating...

Yep - just to reiterate (and hopefully make it more clear):
The line:
import com.fred.MyClass;
Is _not enough_ to get Flash to compile MyClass into your .swf file.
You need to actually _reference_ MyClass for it to be included.
e.g. var a:MyClass=new MyClass();
In fact, import is _nothing to d

There is a bit of an anomaly with importing classes...
For example you have 3 classes. Let's call them FirstClass, SecondClass and
ThirdClass
Derek,
Where did you place those imports? On the timeline, or in an external AS
class file? Would it make a difference?

import in flash is only used to save you some typing.

Also interesting to note here.
If you make two layers in the timeline and in the top layer you put
x = 10;
And the bottom layer you put
trace(x);
you'll get 10.
However, if in the top layer you put
import SomeStaticClass;
And in the bottom layer you put
SomeStaticClass.someMethod();

The 'import' statement doesn't actually embed a class into
the .swf.
All it does is tell the compiler that when you type (for example)
MyClass, you are actually referring
as 42.5 KB ... so, trim the fat and use []
notation!

I think what he is asking is if this is the same as import:
var myObj:mx.core.UIObject = new mx.core.UIObject;
I think one of the answers is that it saves on typing out the class info for
every reference. Any other benefits to import?

All it does is tell the compiler that when you type (for example)
MyClass, you are actually referring to com.fred.MyClass.
You could just type com.fred.MyClass throughout the body
ok its early for me but I think you dont actually need to import if
you provide the full classpath for your datatypes:
private var myVar:com.blah.MyDataType
will work just fine, without an import, i beleive. however, if you
wanted to do:
private var myVar:MyDataType;
then you would need to te
import in AS2, is to help you avoid typing in the complete package name
everytime u reference a class.
The following code

var playBtn:Button;

var stopBtn:Button;
var pauseBtn:Button;
will look like this:

If you are talking about flash, no i believe it doesnt automatically import
your class for you.
You may be getting confused with the new Flex Builder 2 which does infact
import automatically for you.
