NarrowClassRefForm

public NarrowClassRefForm(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.

NarrowClassRefForm
