java.lang.Object

weka.knowledgeflow.steps.BaseStep

weka.knowledgeflow.steps.WekaAlgorithmWrapper

weka.knowledgeflow.steps.ASSearchStrategy

All Implemented Interfaces:

java.io.Serializable, BaseStepExtender, Step

@KFStep(name="ASSearchStrategy",
        category="AttSelection",
        toolTipText="Weka attribute selection search wrapper",
        iconPath="")
public class ASSearchStrategy
extends WekaAlgorithmWrapper

Step that wraps a Weka attribute selection search strategy. This is just an "info" step - i.e. it needs to be connection (via an StepManager.CON_INFO) connection to a ASEvaluator step.

ASSearchStrategy

public ASSearchStrategy()

Method Detail

stepInit

public void stepInit()

Initialize the step

getIncomingConnectionTypes

public java.util.List<java.lang.String> getIncomingConnectionTypes()

Get a list of incoming connections that this step accepts. This step is an info only step, so no incoming connections are allowed

Returns:

a list of connections that this step accepts

getOutgoingConnectionTypes

public java.util.List<java.lang.String> getOutgoingConnectionTypes()

Get a list of outgoing connections from this step. This step is an info only step, so the only outgoing connection is of type "info".

Returns:

a list of outgoing connections

getWrappedAlgorithmClass

public java.lang.Class getWrappedAlgorithmClass()

Get the class of the algorithm wrapped by this wrapper step (ASSearch in this case).

Specified by:

getWrappedAlgorithmClass in class WekaAlgorithmWrapper

Returns:

the class of the wrapped algorithm

setWrappedAlgorithm

public void setWrappedAlgorithm(java.lang.Object algo)

Set the actual algorithm wrapped by this instance

Overrides:

setWrappedAlgorithm in class WekaAlgorithmWrapper

Parameters:

algo - the algorithm wrapped

setSearchStrategy

@ProgrammaticProperty
public void setSearchStrategy(ASSearch searchStrategy)

Set the search strategy wrapped by this step (calls setWrappedAlgorithm)

Parameters:

searchStrategy - the search strategy to wrap

getSearchStrategy

public ASSearch getSearchStrategy()

Get the search strategy wrapped by this step

Returns:
