addBinary

public void addBinary(Feature feature)

Add a binary feature.

getWeight

public double getWeight(Feature feature)

Get the weight assigned to a feature in this instance.

binaryFeatureIterator

public java.util.Iterator<Feature> binaryFeatureIterator()

Return an iterator over all binary features

numericFeatureIterator

public java.util.Iterator<Feature> numericFeatureIterator()

Return an iterator over all numeric features

featureIterator

public java.util.Iterator<Feature> featureIterator()

Return an iterator over all features

numFeatures

public int numFeatures()

Description copied from interface: Instance

Return the number of all the features
