        Parameters:
        name - the name of the symbol
        value - the new value to give that symbol

      • invoke

        public java.lang.Object invoke​(java.lang.String name,
                               java.lang.Object[] args)
        Description copied from interface: IExternalSymbolMap
        Invokes the named external function with the given arguments. The name argument should correspond to the result of calling getName() on the external function symbol.
