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.
Syntax
%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.
See also
- Contrast with Copy which does not copy any nested objects.
- For more information about copyability, see "Copying objects".
