public class Min extends AbstractStorelessUnivariateStatistic implements 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 |
clear()
Clears the internal state of the Statistic
|
Min |
copy()
Returns a copy of the statistic with the same internal state.
|
static void |
copy(Min source,
Min dest)
Copies source to dest.
|
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.
