public class NewClassRefForm
extends ClassRefForm

This class is an extension of the ClassRefForm. It has two purposes: 1. To keep track of the last type used in a new() instruction in the current class. 2. To allow the sender to create instances of either a specified class (which then becomes the new class) or the last used new class.

Method Details

setByteCodeOperands

public void setByteCodeOperands(ByteCode byteCode,
 OperandManager operandManager,
 int codeLength)

Description copied from class: ByteCodeForm

When passed a byteCode, an OperandTable and a SegmentConstantPool, this method will set the rewrite of the byteCode appropriately.

Overrides:

setByteCodeOperands in class ReferenceForm

Parameters:

byteCode - ByteCode to be updated (!)

operandManager - OperandTable from which to draw info

codeLength - Length of bytes (excluding this bytecode) from the beginning of the method. Used in calculating padding for some variable-length bytecodes (such as lookupswitch, tableswitch).
