org.apache.commons.compress.harmony.unpack200.bytecode.forms.NoArgumentForm

public class NoArgumentForm
extends ByteCodeForm

This class implements the byte code form of all bytecodes which either have no operands (such as nop) or have all their operands passed on the stack (not encoded as bytes in the bytecode streams).

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.

Specified by:

setByteCodeOperands in class ByteCodeForm

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).
