Assume I have an array with references to different display objects on the stage. The display objects do not have any other explicit references except for the array indexes. How do I evaluate if a certain index of the array is a reference to a certain display object?

Some code to clarify:

Assume:  
objArr[1] = dispObj1;  
objArr[2] = dispObj2;  
objArr[3] = dispObj3;

function performSomeActionOnObj( ):void  
{[INDENT] for( var i:int = 0; i \< objArr.length; i ++)  
{[INDENT]// problematic step  
// how do I compare array index to display object  
// when display object does not have an explicit  
// reference within the display list?  
if( [COLOR=Red]**objArr[i] == dispObj2**[/COLOR] [COLOR=Red] **/_???_/** [/COLOR] )  
[/INDENT][/INDENT][INDENT][INDENT] {  
[/INDENT][/INDENT][INDENT][INDENT][INDENT] dispObj2.foo( );  
[/INDENT][/INDENT][/INDENT][INDENT][INDENT] }  
[/INDENT][/INDENT][INDENT][INDENT] else  
[/INDENT][/INDENT][INDENT][INDENT] {  
[/INDENT][/INDENT][INDENT][INDENT][INDENT] return;  
[/INDENT][/INDENT][/INDENT][INDENT][INDENT] }  
[/INDENT][/INDENT][INDENT] }  
[/INDENT]}
