SWF Internal Functions

Since Flash version 5, you can use internal functions (really member functions or methods of internal objects.) These functions are always available. These methods are called using the Call Function action with the name of the object and function separated by a period. A few of these internal functions are duplicates of some direct action script instructions. In general, it is preferred to use these internal functions rather than the direct action. However, direct actions are a good way to optimize your ActionScript code.

Similarly, you can access internal constants (really variable ...

Enumerate Object

SWF Action
Action Category: 
Objects
Action Details: 
0
Action Identifier: 
85
Action Structure: 
<n.a.>
Action Length: 
0 byte(s)
Action Stack: 
pop 1 (o), push null, push * (s)
Action Operation: 
o1 := pop();
push(null);
foreach(o1 as name) {
  push(name);
}
Action Flash Version: 
6

Pop an object from the stack, push a null, then push the name of each variable and function member of that object on the stack.

This mechanism can be used to implement a foreach() function on an object. Be careful, though, that the stack be cleared when leaving the loop.

This action uses an object reference. If you only have the name of the object, use the Enumerate action instead.

Action Structure:

push(null);
foreach(s1 as name) {

}
Action Flash Version: 
5

Pop the name of an object and push the name of all of its children (methods & variables) back on the stack. The list is null terminated.

This mechanism can be used to implement a foreach() function on an object. Be careful, though, that the stack be 100% cleared when leaving the loop.

This action uses the name of an object. If you have an object reference, use the Enumerate Object action instead.
