public class AttributeWeightsApplier
extends Operator

This operator deselects attributes with a weight value of 0.0. The values of the other numeric attributes will be recalculated based on the weights delivered as AttributeWeights object in the input.

This operator can hardly be used to select a subset of features according to weights determined by a former weighting scheme. For this purpose the operator AttributeWeightSelection should be used which will select only those attribute fulfilling a specified weight relation.
