Method Detail

hasUnusedParameters

public boolean hasUnusedParameters()

Description copied from interface: Parameterization

Check for unused parameters

Returns:

true if at least one parameter was not consumed

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
