Class Instruction

java.lang.Object
  Instruction

public class Instruction
extends Object

This class represents one Darwin instruction. Instructions contain two parts: an opcode and an address. For instructions that do not perform jumps (hop, left, right, infect), the address part is not used. The fill instruction set is the following:

   hop
   left
   right
   infect
   ifempty
   ifwall
   ifsame
   ifenemy
   ifrandom
   go
 

The following instructions require a target address to jump to:

ifempty, ifwall, ifsame, ifenemy, ifrandom, go

Field Summary

static int	GO opcode for the go instruction
static int	HOP opcode for the hop instruction
static int	IFEMPTY opcode for the ifempty instruction
static int	IFENEMY opcode for the ifenemy instruction
static int	IFRANDOM opcode for the ifrandom instruction
static int	IFSAME opcode for the ifsame instruction
static int	IFWALL opcode for the ifwall instruction
static int	INFECT opcode for the infect instruction
static int	LEFT opcode for the left instruction
static int	RIGHT opcode for the right instruction

Constructor Summary

Instruction(int opcode, int address)
Creates a new instruction.

Method Summary

int	getAddress() Returns the addrss
int	getOpcode() Returns the opcode
String	toString() Returns a printable representation of an Instruction

Constructor Detail

Instruction

public Instruction(int opcode,
                   int address)

Creates a new instruction. address is the target of the operation, if one is needed. Otherwise it is not used.

Method Detail

getOpcode

public int getOpcode()

Returns the opcode

getAddress

public int getAddress()

Returns the addrss

toString

public String toString()

Returns a printable representation of an Instruction

Overrides:
