  - ### stepInit

    public void stepInit()
    Initialize the step

  - ### processIncoming

    public void processIncoming(Data data) throws WekaException
    Process an incoming data payload (if the step accepts incoming connections)
    Specified by:
      `processIncoming` in interface `BaseStepExtender`
    Specified by:
      `processIncoming` in interface `Step`
    Overrides:
      `processIncoming` in class `BaseStep`
    Parameters:
      `data` - the data to process
    Throws:
      `WekaException` - if a problem occurs

  - ### getIncomingConnectionTypes

    public List<String> getIncomingConnectionTypes()
    Get a list of incoming connection types that this step can accept. Ideally (and if appropriate), this should take into account the state of the step and any existing incoming connections. E.g. a step might be able to accept one (and only one) incoming batch data connection.
    Returns:
      a list of incoming connections that this step can accept given its current state

  - ### getOutgoingConnectionTypes

    public List<String> getOutgoingConnectionTypes()
    Get a list of outgoing connection types that this step can produce. Ideally (and if appropriate), this should take into account the state of the step and the incoming connections. E.g. depending on what incoming connection is present, a step might be able to produce a trainingSet output, a testSet output or neither, but not both.
    Returns:
      a list of outgoing connections that this step can produce

  - ### outputStructureForConnectionType

    public Instances outputStructureForConnectionType(String connectionName) throws WekaException
    If possible, get the output structure for the named connection type as a header-only set of instances. Can return null if the specified connection type is not representable as Instances or cannot be determined at present.
    Specified by:
      `outputStructureForConnectionType` in interface `Step`
    Overrides:
      `outputStructureForConnectionType` in class `BaseStep`
    Parameters:
      `connectionName` - the name of the connection type to get the output structure for
    Returns:
      the output structure as a header-only Instances object
    Throws:
      `WekaException` - if a problem occurs
