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 classVectorValueComparator<TimeStampVector>
- 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
Description copied from class:VectorValueComparator
Creates a comparator of the same type.- Specified by:
createNew
in classVectorValueComparator<TimeStampVector>
- Returns:
- the newly created comparator.
