Description
Keyword; lets you access classes without specifying their fully qualified names. For example, if you
want to use a custom class macr.util.users.UserClass in a script, you must refer to it by its fully
qualified name or import it; if you import it, you can refer to it by the class name:
// before importing
var myUser:macr.util.users.UserClass = new macr.util.users.UserClass();
// after importing
import macr.util.users.UserClass;
var myUser:UserClass = new UserClass();
If there are several class files in the package (
want to access, you can import them all in a single statement, as shown in the following example:
import macr.util.users.*;
You must issue the
specifying its name.
If you import a class but don't use it in your script, the class isn't exported as part of the SWF file.
This means you can import large packages without being concerned about the size of the SWF
file; the bytecode associated with a class is included in a SWF file only if that class is actually used.
