Method Details

getOffset

protected abstract int getOffset(OperandManager operandManager)

getPoolID

protected abstract int getPoolID()

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).

setNestedEntries

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

Throws:

Pack200Exception
