Class Associator

  • All Implemented Interfaces:
    java.io.Serializable, BaseStepExtender, Step
    @KFStep(name="Associator",
        category="Associations",
        toolTipText="Weka associator wrapper",
        iconPath="")
public class Associator
extends WekaAlgorithmWrapper
    Step that wraps a Weka associator. Handles dataSet, trainingSet and testSet incoming connections. All connections are treated the same - i.e. are used as training data.

    • Method Detail

      • getWrappedAlgorithmClass

        public java.lang.Class getWrappedAlgorithmClass()
        Get the class of the algorithm being wrapped
        Specified by:
        getWrappedAlgorithmClass in class WekaAlgorithmWrapper
        Returns:
        the class of the wrapped algorithm

      • setWrappedAlgorithm

        public void setWrappedAlgorithm​(java.lang.Object algo)
        Set the wrapped algorithm
        Overrides:
        setWrappedAlgorithm in class WekaAlgorithmWrapper
        Parameters:
        algo - the wrapped algorithm

      • setAssociator

        @ProgrammaticProperty
public void setAssociator​(Associator associator)
        Set the associator to use. Is a convenience method - just calls setWrappedAlgorithm()
        Parameters:
        associator - the associator to use

      • getAssociator

        public Associator getAssociator()
        Get the associator to use. Is a convenience method - just calls getWrappedAlgorithm()
        Returns:
        the associator in use

      • getIncomingConnectionTypes

        public java.util.List<java.lang.String> getIncomingConnectionTypes()
        Get a list of incoming connection types that this step can accept at this time
        Returns:
        a list of incoming connections that this step can accept

      • getOutgoingConnectionTypes

        public java.util.List<java.lang.String> getOutgoingConnectionTypes()
        Get a list of outgoing connections that this step can produce at this time
        Returns:
        a list of outgoing connection types

      • outputStructureForConnectionType

        public Instances outputStructureForConnectionType​(java.lang.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 connection type to generate output structure for
        Returns:
        the output structure this step generates, or null if it can't be determined at this point in time
        Throws:
        WekaException - if a problem occurs
