public class Min extends AbstractStorelessUnivariateStatistic implements AggregatableStatistic<Min>, Serializable
NaN iff all values are NaN
(i.e. NaN values have no impact on the value of the statistic).Double.NEGATIVE_INFINITY,
the result is Double.NEGATIVE_INFINITY.
Note that this implementation is not synchronized. If
multiple threads access an instance of this class concurrently, and at least
one of the threads invokes the increment() or
clear() method, it must be synchronized externally.
| Constructor and Description |
|---|
Min()
Create a Min instance.
|
Min(Min original)
Copy constructor, creates a new
Min identical
to the original. |
| Modifier and Type | Method and Description |
|---|---|
void |
aggregate(Min other)
Aggregates the provided instance into this instance.
|
void |
clear()
Clears the internal state of the Statistic
|
Min |
copy()
Returns a copy of the statistic with the same internal state.
|
double |
evaluate(double[] values,
int begin,
int length)
Returns the minimum of the entries in the specified portion of
the input array, or
Double.NaN if the designated subarray
is empty. |
long |
getN()
Returns the number of values that have been added.
|
double |
getResult()
Returns the current value of the Statistic.
|
void |
increment(double d)
Updates the internal state of the statistic to reflect the addition of the new value.

This method can be used to combine statistics computed over partitions or subsamples - i.e., the value of this instance after this operation should be the same as if a single statistic would have been applied over the combined dataset.
