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.

NewClassRefForm

public NewClassRefForm(int opcode,
 String name,
 int[] rewrite)

Constructs a new instance with the specified opcode, name, operandType and rewrite.

Parameters:

opcode - index corresponding to the opcode's value.

name - String printable name of the opcode.

rewrite - Operand positions (which will later be rewritten in ByteCodes) are indicated by -1.

Method Details

setByteCodeOperands

public void setByteCodeOperands(ByteCode byteCode,
 OperandManager operandManager,
 int codeLength)
                         throws Pack200Exception

Description copied from class: ByteCodeForm

Sets the rewrite of the byteCode.

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).

Throws:

Pack200Exception - if a type is not supported or an index not in the range [0, Integer.MAX_VALUE].
