Implements SampleValue.
|
virtual |
get the nearest (with the least distance to this sample value) sample value whose embedded value equals the specified target
t | the target embedded value |
If two or more target sample values have equal distance each of them should be returned with equal probability.
The returned SampleValue object should be deleted by the callser.
