Deep Copy the Arraylist (Arraylist class)

DeepCopy makes a "deep copy" of the Arraylist method object, al. If al contains objects, they are copied. If al is Null, a Null is returned.


%copyList = al:DeepCopy

Syntax terms

%copyList An Arraylist to contain the deep copy of the method object, al.
al An Arraylist object, which may be Null.

Usage notes

  • Although Arraylist objects in general are deep copyable, a particular Arraylist might contain references to non-deep-copyable objects, which disallows deep copy of that specific Arraylist.

  • Contrast with Copy which does not copy any nested objects.
