public interface VectorValueEqualizer<V extends ValueVector>
extends Cloneable

A function to determine if two vectors are equal at specified positions.

Method Summary

Modifier and Type	Method	Description
VectorValueEqualizer<V>	clone()	Creates a equalizer of the same type.
boolean	valuesEqual(V vector1, int index1, V vector2, int index2)	Checks if the vectors are equal at the given positions, given that the values at both positions are non-null.

Method Details

valuesEqual

boolean valuesEqual(V vector1,
 int index1,
 V vector2,
 int index2)

Checks if the vectors are equal at the given positions, given that the values at both positions are non-null.

Parameters:

vector1 - the first vector.

index1 - index in the first vector.

vector2 - the second vector.

index2 - index in the second vector.

Returns:

true if the two values are considered to be equal, and false otherwise.

clone

VectorValueEqualizer<V> clone()

Creates a equalizer of the same type.

Returns:

the newly created equalizer.
