Using methods with return values
Use CORBA methods that return values as you would any ColdFusion function; for example:
Using IDL types with ColdFusion variables
The following sections describe how ColdFusion supports CORBA data types. They include a
table of supported IDL types and information about how ColdFusion converts between CORBA
types and ColdFusion data.
IDL Support
The following table shows which CORBA IDL types ColdFusion supports, and whether they can
be used as parameters or return variables. (NA means not applicable.)
IDL
double method(out double a);
