* in the byte code for this method.

* {@link InstructionList} associated with this {@link MethodGenerator}.
* </li></ul></p>
* @param lvg the {@link LocalVariableGen} for the variable
* @param offset the position in the byte code
* @return <code>true</code> if and only if the specified variable is in
