Method Detail

getDistance

public float getDistance(AtomEnvironmentList object1,
                         AtomEnvironmentList object2)
                  throws Exception

Calls AtomEnvironmentList.hellinger(AtomEnvironmentList) and divides on 2 to get it in (0,1) range.

 1 - objects are same
 0 - objects are different
 

Specified by:

getDistance in interface IDistanceFunction<AtomEnvironmentList>

Returns:

the distance

Throws:

Exception

getNativeComparison

public float getNativeComparison(AtomEnvironmentList object1,
                                 AtomEnvironmentList object2)
                          throws Exception

Description copied from interface: IDistanceFunction

Calculates native comparison index between two objects (distance or similarity). Similarity is large if objects are similar to each other, in contrast with IDistanceFunction.getDistance(Object, Object).

Specified by:

getNativeComparison in interface IDistanceFunction<AtomEnvironmentList>

Returns:

the distance

Throws:

Exception

toString

public String toString()

Overrides:

toString in class Object
