    + * This is the base implementation of a NiFi input operator.&nbsp;
    + * Subclasses should implement the methods which convert NiFi DataPackets to tuples and
emit them.
    + * <p>
    + * Ports:<br>
    + * <b>Input</b>: No input port<br>
    + * <b>Output</b>: Can have any number of output ports<br>
    + * <br>
    + * Properties:<br>
    + * None<br>
    + * <br>
    + * Compile time checks:<br>
    + * Classes derived from this have to implement the abstract methods emitTuples(List<T>
tuples)&nbsp;
    + * and createTuple(DataPacket dp)<br>
