Method Details

compare

public int compare(EnhancedVector v1,
 EnhancedVector v2)

Compares two PopulationChangeVector objects. First vector are compared according to the position of their rightmost non-zero element Then the number of non zero elements (h) Then the value at the non-zero positions, left to right

Specified by:

compare in interface Comparator<EnhancedVector>

Parameters:

v1 - , v2 The PopulationChangeVectors to be compared.

v2 - the v2 parameter

Returns:

-1 if this < o, 0 if this = o, 1 if this > o
