public PuData()

Method Detail

toString

public static java.lang.String toString(double[] data)

public static java.lang.String toString(float[] data)

Create single line string of float array where components are separated by blanks.

Returns:

single-line string, or null of argument==null or zero length.

toString

public static java.lang.String toString(int[] data)

Create single line string of integer array where components are separated by blanks.

Returns:

copy

public static double[] copy(double[] data,
                            int size)

Copy an array into a new array.

Parameters:

data - source array

size - size of new array, must be less or equal data.length

copy

public static float[] copy(float[] data,
                           int size)

Copy an array into a new array.

Parameters:

data - source array

size - size of new array, must be less or equal data.length

copy

public static int[] copy(int[] data,
                         int size)

Copy an array into a new array.

Parameters:

data - source array

size - size of new array, must be less or equal data.length

realloc

public static java.lang.Object[] realloc(java.lang.Class cl,
                                         java.lang.Object[] data,
                                         int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

The effect is that of the equivalent array creation expression: new cl[size] and copying of existing data into this new array.

Parameters:

data - source array, may be null.

size - size of new array

realloc

public static double[] realloc(double[] data,
                               int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

Parameters:

data - source array, may be null.

size - size of new array

realloc

public static float[] realloc(float[] data,
                              int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

Parameters:

data - source array, may be null.

size - size of new array

realloc

public static int[] realloc(int[] data,
                            int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

Parameters:

data - source array, may be null.

size - size of new array

realloc

public static boolean[] realloc(boolean[] data,
                                int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

Parameters:

data - source array, may be null.

size - size of new array

realloc

public static java.lang.String[] realloc(java.lang.String[] data,
                                         int size)

Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

Parameters:

data - source array, may be null.
