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.

ClassSpecificReferenceForm

public ClassSpecificReferenceForm(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.

setNestedEntries

protected void setNestedEntries(ByteCode byteCode,
 OperandManager operandManager,
 int offset)
                         throws Pack200Exception

Description copied from class: ReferenceForm

Sets the nested entries.

Overrides:

setNestedEntries in class ReferenceForm

Parameters:

byteCode - byte codes.

operandManager - Operand manager.

offset - offset.

Throws:
