Field Detail

preprocessorHandler

private final PreprocessorHandler<O extends DatabaseObject,P extends Preprocessor<O>> preprocessorHandler

The handler class for the preprocessor.

Constructor Detail

AbstractPreprocessorBasedDistanceFunction

public AbstractPreprocessorBasedDistanceFunction(Pattern pattern)

Provides a super class for distance functions needing a preprocessor

Parameters:

pattern - a pattern to define the required input format

Method Detail

setDatabase

public void setDatabase(Database<O> database,
                        boolean verbose,
                        boolean time)

Runs the preprocessor on the database.

Specified by:

setDatabase in interface MeasurementFunction<O extends DatabaseObject,D extends Distance<D>>

Overrides:

setDatabase in class AbstractMeasurementFunction<O extends DatabaseObject,D extends Distance<D>>

Parameters:

database - the database to be set

verbose - flag to allow verbose messages while performing the method

time - flag to request output of performance time

See Also:

MeasurementFunction.setDatabase(de.lmu.ifi.dbs.elki.database.Database, boolean, boolean)

setParameters

public String[] setParameters(String[] args)
                       throws ParameterException

Sets the values for the parameters delta and preprocessor if specified. If the parameters are not specified default values are set.

Specified by:

setParameters in interface Parameterizable

Overrides:

setParameters in class AbstractParameterizable

Parameters:

args - parameters to set the attributes accordingly to

Returns:

String[] an array containing the unused parameters

Throws:

ParameterException - in case of wrong parameter-setting

See Also:

Parameterizable.setParameters(String[])

getAttributeSettings

Returns the parameter setting of the attributes.

Specified by:

getAttributeSettings in interface Parameterizable

Overrides:

getAttributeSettings in class AbstractParameterizable

Returns:

the parameter setting of the attributes

See Also:

Parameterizable.getAttributeSettings()

getPreprocessor
