Method Detail

Execute

public void Execute(SECDMachine machine)
Description copied from class: LispPrimitive
Execute performs the operation using the abstract machine registers. Arguments are found on the S register stack, in reverse order. UNLIMITED argument lists are collected into a list which is the top element on the stack. The implementation should pop an appropriate number of arguments from the stack, perform a computation, then push a result back on the S stack. The instruction should then be popped from the C (code) register. A LispValueFactory objects is available in the static variable LispValueFactory. Example implementations:
   FIRST
   class FirstPrimitive extends LispPrimitive
   {
     public First()
     {
       super("FIRST", 1);   // 1 argument
     }

     public void Execute(SECDMachine machine)
     {
       LispValue arg = machine.S.pop();

       machine.S.push(my_first(arg));
       machine.C.pop();
     }
   }
 
A multi-argument function must pop the arguments in reverse order.
     public void Execute(SECDMachine machine)
     {
       LispValue arg2 = machine.S.pop();
       LispValue arg1 = machine.S.pop();

       machine.S.push(my_new_function(arg1, arg2));
       machine.C.pop();
     }
   }
 
To register the new primitive, call:
    Jatha.COMPILER.Register(new FirstPrimitive());
 

Specified by:
Execute in class LispPrimitive
Parameters:
