| Method Summary | |
| void | clear()
| | 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. | | void | incrementAll(double[] values)
Updates the internal state of the statistic to reflect addition of
all values in the values array. | | void | incrementAll(double[] values, int start, int length)
Updates the internal state of the statistic to reflect addition of
the values in the designated portion of the values array. |
| clear | | void clear()(Code) | | Clears the internal state of the Statistic
|
| getN | | long getN()(Code) | | Returns the number of values that have been added.
the number of values. |
| getResult | | double getResult()(Code) | | Returns the current value of the Statistic.
value of the statistic, Double.NaN if ithas been cleared or just instantiated. |
| increment | | void increment(double d)(Code) | | Updates the internal state of the statistic to reflect the addition of the new value.
Parameters:
d - the new value. |
| incrementAll | | void incrementAll(double[] values)(Code) | | Updates the internal state of the statistic to reflect addition of
all values in the values array. Does not clear the statistic first --
i.e., the values are added incrementally to the dataset.
Parameters:
values - array holding the new values to add
throws:
IllegalArgumentException - if the array is null |
| incrementAll | | void incrementAll(double[] values, int start, int length)(Code) | | Updates the internal state of the statistic to reflect addition of
the values in the designated portion of the values array. Does not
clear the statistic first -- i.e., the values are added
incrementally to the dataset.
Parameters:
values - array holding the new values to add
Parameters:
start - the array index of the first value to add
Parameters:
length - the number of elements to add
throws:
IllegalArgumentException - if the array is null or the index |
