Overloading functions in slice

Sameerrele

I am trying to understand Ice and the underlying architecture and would appreciate any help in the following matter

My slice file is
module com
{
module xxx
{
module foo
{
module service
{
interface SomeService
{
bool isValidTradeDate(string country, string date ) ;
bool isValidTradeDate(string country, string date, string dateFormat ) ;
};
};
};
};
};


As you can see I am trying to overload the function isValidTradeDate by passing dateformat as extra parameter

When I run
c:\Ice-3.1.0\bin\slice2java --output-dir c:\kill\src someservice.ice

I get the following error

someservice.ice:12: redefinition of operation `isValidTradeDate' as operation `isValidTradeDate'


How do I overload a function? Is it supported?

If this is a stupid question please educate me.

Thanks

Hi Sameer,

Slice does not support overloaded operations because not all target languages support function overloading (such as Python). You'll need to use a different name for each version of the operation.

In addition, allowing operation overloading would also make the Ice protocol much more complicated, because you could not only simply transfer the operation name, but would have to transfer the signature of the operation as well, so that the server knows which version of the operation to call.
