public abstract class ClassSpecificReferenceForm
extends ReferenceForm

Abstract superclass of all classes that have class-specific references to constant pool information. These classes have a context (a string representing a pack200 class) i.e., they send getClassSpecificPoolEntry instead of getConstantPoolEntry.

Constructor Detail

ClassSpecificReferenceForm

public ClassSpecificReferenceForm(int opcode,
                                  java.lang.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.
