Constructor Details

SendToPerspective

public SendToPerspective()

Method Details

setPerspectiveName

public void setPerspectiveName(String name)

getPerspectiveName

public String getPerspectiveName()

stepInit

public void stepInit()
              throws WekaException

Description copied from interface: Step

Initialize the step.

Throws:

WekaException - if a problem occurs during initialization

processIncoming

public void processIncoming(Data data)
                     throws WekaException

Description copied from class: BaseStep

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 payload to process

Throws:

WekaException - if a problem occurs

getIncomingConnectionTypes

public List<String> getIncomingConnectionTypes()

Description copied from interface: Step

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()

Description copied from interface: Step

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
