public class FeatureBlockTypeFilter
extends FeatureFilter

This operator switches off all features whose block type matches the one given in the parameter skip_features_of_type. This can be useful e.g. for preprocessing operators that can handle only series attributes.

Method Detail

switchOffFeature

public boolean switchOffFeature(AttributeRole role)
                         throws OperatorException

Implements the method required by the superclass. For features whose type is a subtype of the one given as a parameter for this operator, TRUE is returned (otherwise FALSE). If no parameter was provided, FALSE is always returned, so no feature is switched off.

Specified by:

switchOffFeature in class FeatureFilter

Parameters:

role - Feature to check.

Returns:

TRUE if this feature should not be active in the output example set of this operator. FALSE otherwise.

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class FeatureFilter
