Saver

public Saver()

Method Details

getWrappedAlgorithmClass

public Class getWrappedAlgorithmClass()

Get the class of the wrapped algorithm

Specified by:

getWrappedAlgorithmClass in class WekaAlgorithmWrapper

Returns:

the class of the wrapped algorithm

setWrappedAlgorithm

public void setWrappedAlgorithm(Object algo)

Set the actual wrapped algorithm instance

Overrides:

setWrappedAlgorithm in class WekaAlgorithmWrapper

Parameters:

algo - the wrapped algorithm instance

getSaver

public Saver getSaver()

Get the saver instance that is wrapped by this step. Convenience method that delegates to getWrappedAlgorithm()

Returns:

the saver instance that is wrapped by this step

setSaver

@ProgrammaticProperty
public void setSaver(Saver saver)

Set the saver instance that is wrapped by this step. Convenience method that delegates to setWrappedAlgorithm().

Parameters:

saver - the saver instance that is wrapped by this step

getRelationNameForFilename

public boolean getRelationNameForFilename()

Get whether the relation name is the primary part of the filename.

Returns:

true if the relation name is part of the filename.

setRelationNameForFilename

public void setRelationNameForFilename(boolean r)

Set whether to use the relation name as the primary part of the filename. If false, then the prefix becomes the filename.

Parameters:

r - true if the relation name is to be part of the filename.

stepInit

public void stepInit()
              throws WekaException

Initialize the step

Specified by:

stepInit in interface BaseStepExtender

Specified by:

stepInit in interface Step

Throws:

WekaException - if a problem occurs during initialization

processIncoming

public void processIncoming(Data data)
                     throws WekaException

Processes incoming data

Specified by:

processIncoming in interface BaseStepExtender

Specified by:

processIncoming in interface Step

Overrides:

processIncoming in class BaseStep

Parameters:

data - the data process

Throws:

WekaException - if a problem occurs

getIncomingConnectionTypes

public List<String> getIncomingConnectionTypes()

Get a list of incoming connection types that this step can receive at this time

Specified by:

getIncomingConnectionTypes in interface BaseStepExtender

Specified by:

getIncomingConnectionTypes in interface Step

Returns:

a list of incoming connection types

getOutgoingConnectionTypes

public List<String> getOutgoingConnectionTypes()

Get a list of outgoing connection types that this step can produce at this time

Specified by:

getOutgoingConnectionTypes in interface BaseStepExtender

Specified by:

getOutgoingConnectionTypes in interface Step

Returns:

a list of outgoing connection types

getCustomEditorForStep

public String getCustomEditorForStep()

Return the fully qualified name of a custom editor component (JComponent) to use for editing the properties of the step. This method can return null, in which case the system will dynamically generate an editor using the GenericObjectEditor

Specified by:

getCustomEditorForStep in interface Step

Overrides:

getCustomEditorForStep in class BaseStep

Returns:

the fully qualified name of a step editor component
