public class FeatureSet

extends Object

This class stores pairs of features and counts.

Constructor Summary

FeatureSet()
Constructor creates an empty FeatureSet

FeatureSet(HashMap features)
This constructor allows the creation of a FeatureSet from a HashMap of features

Method Summary

void	addFeature(Feature next) Adds the feature "next" to this FeatureSet.
boolean	contains(Feature f) Returns true if the FeatureSet contains Feature f, and false otherwise.
double	getCount(Feature key) Returns the count associated with the Feature key
int	getID() Returns the ID (true classification) of the FeatureSet.
Iterator	getIterator()
int	getSize() Returns the number of features in the FeatureSet
boolean	hasNext() Used when iterating
Object	next() This method returns the next element in the set
void	reset() This method must be called before each iteration through the FeatureSet.
