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.

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).
