public UInt8Comparator()

Method Details

compareNotNull

public int compareNotNull(int index1,
 int index2)

Description copied from class: VectorValueComparator

Compare two values, given their indices. This is a fast path for comparing non-null values, so the caller must make sure that values at both indices are not null.

Specified by:

compareNotNull in class VectorValueComparator<UInt8Vector>

Parameters:

index1 - index of the first value to compare.

index2 - index of the second value to compare.

Returns:

an integer greater than 0, if the first value is greater; an integer smaller than 0, if the first value is smaller; or 0, if both values are equal.

createNew

public VectorValueComparator<UInt8Vector> createNew()

Description copied from class: VectorValueComparator

Creates a comparator of the same type.

Specified by:

createNew in class VectorValueComparator<UInt8Vector>

Returns:

the newly created comparator.
