Method Summary

Modifier and Type	Method and Description
static void	blankArray(double[] objectArray, int startIndex, int endIndex) Method to blank any double[] array elements to its default value from [startIndex; endIndex[, equivalent to Arrays.fill(objectArray, startIndex, endIndex, 0 or null)
static void	reverse(double[] table, int from, int to) Reverse the elements positions of the specified range of array table :
static void	reverse(DoubleIndexedContainer table, int from, int to) Reverse the elements positions of the specified range of DoubleIndexedContainer table :
static void	rotate(double[] table, int from, int mid, int to) Rotate utility : Transforms the range [[slice_1: from; mid - 1][slice_2: mid, to - 1]] of table, into [[slice_2][slice_1]]in place, i.e swap the two slices while keeping their own internal order.
static void	rotate(DoubleIndexedContainer table, int from, int mid, int to) Rotate utility : Transforms the range [[slice_1: from; mid - 1][slice_2: mid, to - 1]] of DoubleIndexedContainer, into [[slice_2][slice_1]] in place, i.e swap the two slices while keeping their own internal order.

Method Detail

rotate

public static void rotate(double[] table,
                          int from,
                          int mid,
                          int to)

Rotate utility : Transforms the range [[slice_1: from; mid - 1][slice_2: mid, to - 1]] of table, into [[slice_2][slice_1]]in place, i.e swap the two slices while keeping their own internal order.

Parameters:

table -

from - the start range to consider

mid - start index of the second slice

to - the array end range, exclusive

rotate

public static void rotate(DoubleIndexedContainer table,
                          int from,
                          int mid,
                          int to)

Rotate utility : Transforms the range [[slice_1: from; mid - 1][slice_2: mid, to - 1]] of DoubleIndexedContainer, into [[slice_2][slice_1]] in place, i.e swap the two slices while keeping their own internal order.

Parameters:

table -

from - the start range to consider

mid - start index of the second slice

to - the array end range, exclusive

reverse

public static void reverse(double[] table,
                           int from,
                           int to)

Reverse the elements positions of the specified range of array table :

Parameters:

table -

from - the start range to consider

to - the array end range, exclusive

reverse

public static void reverse(DoubleIndexedContainer table,
                           int from,
                           int to)

Reverse the elements positions of the specified range of DoubleIndexedContainer table :

Parameters:

table -

from - the start range to consider

to - the array end range, exclusive

blankArray

public static void blankArray(double[] objectArray,
                              int startIndex,
                              int endIndex)

Method to blank any double[] array elements to its default value from [startIndex; endIndex[, equivalent to Arrays.fill(objectArray, startIndex, endIndex, 0 or null)
