      de.lmu.ifi.dbs.elki.utilities.optionhandling.parameterization.SerializedParameterization

All Implemented Interfaces:

Parameterization

public class SerializedParameterization
extends AbstractParameterization

Manage a parameterization serialized as String array, e.g. from command line. When building parameter lists, use ListParameterization where possible.

Field Detail

OPTION_PREFIX

public static final String OPTION_PREFIX

public SerializedParameterization()

Constructor

SerializedParameterization

public SerializedParameterization(String[] args)

Constructor

Parameters:

args - Parameters

SerializedParameterization

public SerializedParameterization(List<String> args)

Constructor

Parameters:

args - Parameter list

Method Detail

getRemainingParameters

public List<String> getRemainingParameters()

Return the yet unused parameters.

Returns:

Unused parameters.

hasUnusedParameters

public boolean hasUnusedParameters()

Description copied from interface: Parameterization

Check for unused parameters

Returns:

true if at least one parameter was not consumed

logUnusedParameters

public void logUnusedParameters()

Log a warning if there were unused parameters.

setValueForOption

public boolean setValueForOption(Parameter<?,?> opt)
                          throws ParameterException

Description copied from class: AbstractParameterization

Perform the actual parameter assignment.

Specified by:

setValueForOption in interface Parameterization

Specified by:

setValueForOption in class AbstractParameterization

Parameters:

opt - Option to be set

Returns:

Success code (value available)

Throws:

ParameterException - on assignment errors.

descend

public Parameterization descend(Object option)

Descend parameterization tree into sub-option. Note: this is done automatically by a ClassParameter.instantiateClass(de.lmu.ifi.dbs.elki.utilities.optionhandling.parameterization.Parameterization). You only need to call this when you want to expose the tree structure without offering a class choice as parameter. Default implementation, for flat parameterizations.

Parameters:

option - Option subtree

Returns:

Parameterization
