Constructor Detail

ShortCPRefInstruction

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

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

---

ShortCPRefInstruction

protected ShortCPRefInstruction(byte command,
                                com.chaoswg.xtc4y.classdesc.ConstantPoolEntry cpEntry)

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

Method Detail

handleOperand

protected void handleOperand(byte 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

Overrides:

handleOperand in class BinaryInstruction

---

getOperand

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

Overrides:

getOperand in class BinaryInstruction
