Copy (Stringlist function)
Copy Stringlist (Stringlist class)
This method copies an entire Stringlist, creating a new Stringlist. The Copy method accepts no argument and returns a Stringlist object. If you are new to object-oriented programming or the Janus APIs you should read about Copying objects.
Copy is a member of the Stringlist class.
Syntax
%outList = sl:Copy
Syntax terms
- %outlist
- A Stringlist to contain the copy of the method Stringlist %sl
- %sl
- A Stringlist object.
Usage notes
- All errors in Copy result in request cancellation.
- If the method Stringlist was associated with an image, by either the BindImage or New method, the output Stringlist is associated with the same image, as if a BindImage method had been invoked on the result of the Copy method.
- Copy does a page-for-page copy of the input Stringlist. As such, it is very efficient (more efficient than CopyItems), but it is also useless for compressing a Stringlist that has become sparse as the result of heavy Insert, Replace, ChangeItemLength, and RemoveItem activity. Replace and ChangeItemLength cause a Stringlist to become sparse only if Stringlist items are replaced with larger Stringlist items or increased in size. For list compression, use CopyItems (Stringlist function).
