Method Summary

Modifier and Type	Method and Description
float	getDistance(T object1, T object2) Distance should be large if objects are "far away" from each other, i.e.
float	getNativeComparison(T object1, T object2) Calculates native comparison index between two objects (distance or similarity).

Method Detail

getDistance

float getDistance(T object1,
                  T object2)
           throws Exception

Distance should be large if objects are "far away" from each other, i.e. dissimilar.

Parameters:

object1 -

object2 -

Returns:

the distance

Throws:

Exception

getNativeComparison

float getNativeComparison(T object1,
                          T object2)
                   throws Exception

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

Parameters:

object1 -

object2 -

Returns:

the distance

Throws:

Exception
