Examples of nexj.core.scripting.Function.invoke()

nexj.core.scripting.Function.invoke()
Invokes a function from the virtual machine. The function should either compute its value immediately and push it on the VM stack, or setup the VM for executing its code, if it is a byte code function. @param nArgCount The number of arguments pushed on the VM stack. @param machine The virtual machine instance. @return True if the virtual machine registers should be reset.


         Function fun = machine.getGlobalEnvironment().findFunction(m_class, (Symbol)selector, nArgCount - 1);


         if (fun != null)
         {
            return fun.invoke(nArgCount, machine);
         }


         fun = m_class.resolveFunction((Symbol)selector, nArgCount - 1);


         if (fun != null)
