weka.knowledgeflow.JobEnvironment

All Implemented Interfaces:

RevisionHandler

public class JobEnvironment
extends Environment

Extended Environment with support for storing results and property values to be set at a later date on the base schemes of WekaAlgorithmWrapper steps. The latter is useful in the case where variables are not supported for properties in a base scheme.

Constructor Detail

JobEnvironment

public JobEnvironment()

Constructor

JobEnvironment

public JobEnvironment(Environment env)

Construct a JobEnvironment by copying the contents of a standard Environment

Parameters:

env - the Environment to copy into this JobEnvironment

Method Detail

addToResult

public void addToResult(Data data)

Add a non-incremental data object to the result

Parameters:

data - the data to add

addAllResults

public void addAllResults(Map<String,LinkedHashSet<Data>> otherResults)

Add all the results from the supplied map to this environment's results

Parameters:

otherResults - the results to add

getResultDataOfType

public LinkedHashSet<Data> getResultDataOfType(String connName)

Get a list of any result data objects of the supplied connection type

Parameters:

connName - the name of the connection to get result data objects for

Returns:

a list of result data objects for the specified connection type, or null if none exist

hasResultDataOfType

public boolean hasResultDataOfType(String connName)

Returns true if the results contain data of a particular connection type

Parameters:

connName - the name of the connection to check for data

Returns:

true if the results contain data of the supplied connection type

getResultData

public Map<String,LinkedHashSet<Data>> getResultData()

Get a map of all the result data objects

Returns:

a map of all result data

clearResultData

public void clearResultData()

getStepProperties

public Map<String,String> getStepProperties(String stepName)

Get the step properties for a named step

Parameters:

stepName - the name of the step to get properties for

Returns:

a map of properties for the named step

clearStepProperties

public void clearStepProperties()

Clear all step properties

addToStepProperties

public void addToStepProperties(Map<String,Map<String,String>> propsToAdd)

Add the supplied map of step properties. The map contains properties for various base schemes owned by scheme-specific (WekaAlgorithmWrapper) steps. Outer map is keyed by step name, inner map by property name.

Parameters:

propsToAdd - properties to add
