372 Chapter 12: ActionScript Dictionary
delete array[2];
trace(my_array.length);
Usage 4: The following example illustrates the behavior of delete on object references.
// create a new object, and assign the variable ref1
// to refer to the object
ref1 = new Object();
ref1.name = "Jody";
// copy the reference variable into a new variable
// and delete ref1
ref2 = ref1;
delete ref1;
If ref1 had not been copied into ref2, the object would have been deleted when ref1 was
deleted, because there would be no references to it. If you delete
ref2, there will no longer be any
references to the object; it will be destroyed, and the memory it was using will be made available.
