Method Summary
Modifier and Type Method Description abstract long
compare(Sample s1, Sample s2)
Compares to sample Must return an long integer that define the relational order of the 2 compared samples: - Negative long integer : s1 is lower than s2
- Zero long integer : s1 is strictly equal to s2
- Positive long integer : s1 is greater than s2
abstract void
initialize(SampleMetadata metadata)
Initializes the comparator with the SampleMetadata of the samples to be compared. -

compare
abstract long compare(Sample s1, Sample s2)
Compares to sample
Must return an long integer that define the relational order of the 2 compared samples:
- Negative long integer : s1 is lower than s2
- Zero long integer : s1 is strictly equal to s2
- Positive long integer : s1 is greater than s2
- Parameters:
s1
- The first sample to be compareds2
- The second sample to compared- Returns:
A negative is
s1 < s2
,0 if s1 = s2
, a positive integer ifs1 > s2
-
initialize
abstract void initialize(SampleMetadata metadata)
Initializes the comparator with the SampleMetadata of the samples to be compared.
This function is invoked before any call to the
compare
service.Not that this function is the place to get sample column indexes for better performance
- Parameters:
metadata
- The metadata of the sample to be compared by this instance
