Converting from ActionScript to application server data types 65
Converting from ActionScript to application server data types
Flash Remoting automatically converts between ActionScript data and the data types specific to
the application server programming environment.
In strictly typed environments, such as Java and C#, the service function data types must
correspond to (or be derived from) the listed data types. In loosely typed programming
environments, such as ColdFusion or Visual Basic, the environment must be able to use the listed
data type for the service function variable.
The following table lists the server data types into which the Flash gateway converts ActionScript
data types:
