Description copied from interface: VectorValueEqualizer

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

Specified by:

valuesEqual in interface VectorValueEqualizer<FloatingPointVector>

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

Description copied from interface: VectorValueEqualizer

Creates a equalizer of the same type.

Specified by:

clone in interface VectorValueEqualizer<FloatingPointVector>

Overrides:

clone in class Object

Returns:

the newly created equalizer.
