Best Practice Makes Perfect | CommentsA collaboration with Domino developers about how to do it and how to get it right in Dominocallbacks in LotusScript- August 6, 2008 I don't know of any foolproof way to get this at compile time either -- without support for interface, delegate, etc.One thing you can to to provide a little bit of compile time type-safety is start with an unimplemented base class that you treat as though it is an interface:Class FNMBaseFunction Mangle(fname$, Byval row%) as stringError 9999, "Mangle not implemented!"End FunctionEnd ClassClass FNMDefault as FNMBase ....Changing your parameters to accept type FNMBase then allows them to receive.http://www-10.lotus.com/ldd/bpmpblog.nsf/dx/ools-callbacks-in-lotusscript?opendocument&... OOLS: callbacks in LotusScript- August 6, 2008 No, this is one of those places where we're really stuck.I'd love to see functions as first-class objects in LS, but that just do happens to be one of the hardest things to program into any compilerinterpreter. At this point, I'm pretty sure that IBM would just rather use javascript for things, where it's already baked in, or Java, where you can do the interface and abstract method things.http://www-10.lotus.com/ldd/bpmpblog.nsf/dx/ools-callbacks-in-lotusscript?opendocument&... OOLS: callbacks in LotusScript - thats easy- August 6, 2008 IBM should extend the Lotusscript compiler and editor. For example you could add code assist for user-defined Lotusscript classes like in the "modern" IDEs...

Do you sign at the top- August 6, 2008 Hello,Thank you for sharing this code example. Maybe you have a bug in your blog software. The last line of your posting shows: "Andre Guirard 12 March 2007 10:45:00 AM ET Plymouth, MN, USA Comments (2)" I count 4 comments without mine. My true reason for my comment is a question.

Callbacks- August 6, 2008 No, no explicit method of making the compiler understand his that I know of.You could take it to the extent of actually passing code in a string, and using 'evaluate' to execute that code (if it were formula) or execute (if it were lotusscript).Neither is recommended - I'd stick with the overriding-class model you outlined above.--- Billhttp://www-10.lotus.com/ldd/bpmpblog.nsf/dx/ools-callbacks-in-lotusscript?opendocument&... |
