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

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

Direct Known Subclasses:

CPRefInstruction, JumpInstruction, NewArray

---

public class WideBinaryInstruction

extends Instruction

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

---

Field Summary
static byte	NEWARRAY           create a new array
private  short	operand
static byte	SIPUSH           push a short onto the stack

 

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

 

Constructor Summary
	WideBinaryInstruction(byte command)           Create a new binary instruction with a command and the short value as operand
protected	WideBinaryInstruction(byte command, java.io.DataInputStream dis, com.chaoswg.xtc4y.classdesc.ConstantPool cp)           Creates an WideBinaryInstruction and initializes it from a DataInputStream

 

Method Summary
int	getNumberOfUsedBytes()
protected  short	getOperand(com.chaoswg.xtc4y.classdesc.ConstantPool cp)
protected  void	handleOperand(short operand, com.chaoswg.xtc4y.classdesc.ConstantPool cp)           Handle operand.
java.lang.String	toString()           Write code in a readable way
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

WideBinaryInstruction

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

Creates an WideBinaryInstruction and initializes it from a DataInputStream

---

WideBinaryInstruction

public WideBinaryInstruction(byte command)

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

Method Detail

handleOperand

protected void handleOperand(short operand,
                             com.chaoswg.xtc4y.classdesc.ConstantPool cp)

Handle operand. By default, the operands value is 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

---

getOperand

protected short getOperand(com.chaoswg.xtc4y.classdesc.ConstantPool cp)

---

getNumberOfUsedBytes

public final int getNumberOfUsedBytes()

Specified by:

getNumberOfUsedBytes in class Instruction

---

toString

public java.lang.String toString()

Write code in a readable way

Overrides:

toString in class Instruction
