com.chaoswg.xtc4y.classdesc.code.instructions
Class TrinaryInstruction  

java.lang.Object
  com.chaoswg.xtc4y.classdesc.code.instructions.Instruction
      com.chaoswg.xtc4y.classdesc.code.instructions.TrinaryInstruction

---

public class TrinaryInstruction

extends Instruction

A binary instruction consists of a command and two one byte operands, therefore its size is 3 bytes

---

Field Summary
static byte	IINC           increment local indexed variable by the second operand
private  byte	operand1
private  byte	operand2

 

Fields inherited from class com.chaoswg.xtc4y.classdesc.code.instructions.Instruction

 

Constructor Summary

TrinaryInstruction(byte command, byte operand1, byte operand2)           Create a new binary instruction with a command and the byte value as operand

TrinaryInstruction(byte command, java.io.DataInputStream dis, com.chaoswg.xtc4y.classdesc.ConstantPool cp)           Creates an TrinaryInstruction and initializes it from a DataInputStream.

 

Method Summary
int	getNumberOfUsedBytes()
protected  byte	getOperand1(com.chaoswg.xtc4y.classdesc.ConstantPool cp)
protected  byte	getOperand2(com.chaoswg.xtc4y.classdesc.ConstantPool cp)
protected  void	handleOperands(byte operand1, byte operand2, com.chaoswg.xtc4y.classdesc.ConstantPool cp)           Handle operands.
void	write(java.io.DataOutputStream dos, com.chaoswg.xtc4y.classdesc.ConstantPool cp)           Write the instruction onto the DataOutputStream, using the constant pool to register variables.

Constructor Detail

TrinaryInstruction

public TrinaryInstruction(byte command,
                          java.io.DataInputStream dis,
                          com.chaoswg.xtc4y.classdesc.ConstantPool cp)
                   throws java.io.IOException

Creates an TrinaryInstruction and initializes it from a DataInputStream. the operand is read from the stream and provided to extending classes for a further handling of it

---

TrinaryInstruction

public TrinaryInstruction(byte command,
                          byte operand1,
                          byte operand2)

Create a new binary instruction with a command and the byte value as operand

Method Detail

handleOperands

protected void handleOperands(byte operand1,
                              byte operand2,
                              com.chaoswg.xtc4y.classdesc.ConstantPool cp)

Handle operands. By default, the operands values are stored. Another behaviour may be implemented in an extending class

---

write

public final void write(java.io.DataOutputStream dos,
                        com.chaoswg.xtc4y.classdesc.ConstantPool cp)
                 throws java.io.IOException

Write the instruction onto the DataOutputStream, using the constant pool to register variables. .

Overrides:

write in class Instruction

---

getOperand1

protected byte getOperand1(com.chaoswg.xtc4y.classdesc.ConstantPool cp)

---

getOperand2

protected byte getOperand2(com.chaoswg.xtc4y.classdesc.ConstantPool cp)

---

getNumberOfUsedBytes

public final int getNumberOfUsedBytes()

Specified by:

getNumberOfUsedBytes in class Instruction
