ByteDecisionNode

public ByteDecisionNode(String feature,
                        int numDaughters,
                        FeatureDefinition featureDefinition)

Build a new byte decision node

Parameters:

feature - the feature name

numDaughters - the number of daughters

featureDefinition - featureDefinition

ByteDecisionNode

public ByteDecisionNode(int featureIndex,
                        int numDaughters,
                        FeatureDefinition featureDefinition)

Build a new byte decision node
