In NB, how do I pass NULL into a function call without modifying the argument type? e.g. my argument has type String. passing something
like
`NBExternalAddress null` will be converted into a C string instead of being passed through (I know, that seems to be the point in this case but I couldn't find any other way to create NULL). Any suggestions?
I think you just pass nil, no?
One would think so, but no⦠:) NB will signal an exception because UndefinedObject is not of the expected type.
I remember an optCoerceNilToNull, but that seems to 1) Only apply to pointer types (which could mean having to use char *, not String, and thus need to do encoding/decoding manually) 2) Be scoped to entire call, not single parameter (may or may not be more than a philosophical objection)
Might be worth a shot though?
- optCoerceNilToNull is for pointers
for strings, there's an option: - optStringOrNull which, if enabled, adds additional check for nil in generated marshaller code, so that by passing nil it will pass NULL to calling function. Cheers,
Henry
