Ah, I think I understand what you mean. I believe the answer is 'no' - the default return value is undefined but there is no way to distinguish between 'not set' and 'prior call to v8::ReturnValue::SetUndefined()' at the API level. It should be possible to add an IsSet() method - I lied by omission; the internal default value is the magic 'the hole' value, which can be used as a discriminator - but I can't comment on whether it would be accepted. You could try filing a CL and see what the V8 team thinks. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
