Hi,
I have registered the function, as suggested
registry.registerAll(model, null);
Function function = registry.getFunction("http://spinrdf.org/spin#accountage";,
model);
SPINARQFunction spinarqFunction = new SPINARQFunction(function);
I get the function too. Now I need an example how to execute this function
using *exec* or *executeBody methods. *I am struck with supplying
arguments to methods. How do I create variables and assign value to it.
It would be of great help, if you could share me the sample code.
Thanks
Raj
