New arrayCollection not by reference

i know can make copy of arraycollection objectutil.copy  or  writing byte array , registering type. happens if take source of existing arraycollection, array itself, , create new array? unreferenced original arraycollection.

 

in code,

 

var myarraycollection:arraycollection. // passed in value

var mynewarraycollection = new arraycollection(myarraycollection.source);

 

is original arraycollection still affected changes in mynewarraycollection, using filterfunctions?

you have new arraycollection , changes underlying array affect both array collections.

 

the array won't copied when arraycollection constructed.

 

the array not passed value - pointer array, not array itself.

 

filter functions belong array collection, array collections independently filtered (filtering same data in differrent ways).
