Constructor Detail

FeatureComparator

public FeatureComparator(int setI,
                 FeatureVector.FeatureType featureType)

Constructor which initializes the feature index.

Parameters:

setI - The index of the feature to be compared on the next run of the comparator.

featureType - feature Type

Method Detail

setFeatureIdx

public void setFeatureIdx(int setI,
                 FeatureVector.FeatureType featureType)

Accessor to set the feature index.

Parameters:

setI - The index of the feature to be compared on the next run of the comparator.

featureType - feature type

getFeatureIdx

public int getFeatureIdx()

Access the index of the currently compared feature.

Returns:

The index of the feature which the comparator currently deals with.

compare

public int compare(FeatureVector a,
          FeatureVector b)

Compares two feature vectors according to their values at an internal index previously set by this.setFeatureIdx().

Specified by:

compare in interface Comparator<FeatureVector>

Parameters:

a - The first vector.

b - The second vector.

Returns:

a negative integer, zero, or a positive integer as the feature at index I for v1 is less than, equal to, or greater than the feature at index I for v2. check setFeatureIdx(int setI, FeatureVector.FeatureType featureType) .

equals

public boolean equals(Object obj)

The equals() method asked for by the Comparable interface. Returns true if the compared object is a FeatureComparator with the same internal index, false otherwise.

Specified by:

equals in interface Comparator<FeatureVector>

Overrides:

equals in class Object

Parameters:

obj - obj

Returns:

false if obj is not instanceof featurecomparator, or if ((featurecomparator) obj).getfeatureIdx() is different from this.I, true otherwise
