public final class doubleArray0D

extends doubleArray

The doubleArray0D concrete class implements 0-dimensional arrays of doubles. 0-dimensional arrays are scalars. Although they can be instantiated directly through constructors, 0-dimensional arrays are typically generated by extracting single-element sections from higher-dimensional arrays.

doubleArray0D()

Create a 0-dimensional array with a 0-valued element.

doubleArray0D(double)

Create a 0-dimensional array.

doubleArray0D(double[], int)

Create a 0-dimensional array as a section of another array.

assign(double)

Assign a scalar value to all elements of the array.

assign(doubleArray0D)

Assign the values from another zero-dimensional array to this array.

get()

Returns the value of the element of the 0-dimensional array, if any.

get(int[])

Return the value of an element of the array.

rank()

Return the rank of the 0-dimensional array, i.e.

set(double)

Sets the value of the element of the 0-dimensional array, if any.

set(int[], double)

Set the value of an element of the array.

shape()

Returns the shape of a 0-dimensional array.

size()

Return the number of elements in the array.

size(int)

A 0-dimensional array does not have any axis.

 public doubleArray0D()

Create a 0-dimensional array with a 0-valued element.

 public doubleArray0D(double a)

Create a 0-dimensional array. The value of the element is specified by a parameter.

Parameters:

a - value of element

 protected doubleArray0D(double d[],
                         int a)

Create a 0-dimensional array as a section of another array. Internal use within the package only. A 0-dimensional array section can be empty (have 0 elements).

 public int rank()

Return the rank of the 0-dimensional array, i.e. 0.

Overrides:

rank in class doubleArray

 public int size()

Return the number of elements in the array. This number is 0 if the array is empty, 1 otherwise.

Overrides:

size in class doubleArray

 public int size(int i) throws InvalidArrayAxisException

A 0-dimensional array does not have any axis. Therefore, any invocation of size(i) throws an InvalidArrayAxisException exception.

Parameters:

i - array axis (0 <= i < rank())

Throws: InvalidArrayAxisException

always thrown

Overrides:

size in class doubleArray

 public int[] shape()

Returns the shape of a 0-dimensional array. This is an int[] of length 0.

Overrides:

shape in class doubleArray

 public double get(int index[]) throws InvalidArrayIndexException, ArrayIndexOutOfBoundsException

Return the value of an element of the array.

Parameters:

index - index[i] = index along i-th axis, 0 <= index[i] < size(i)

Throws: InvalidArrayIndexException

index[] must be of length 0

Overrides:

get in class doubleArray

 public void set(int index[],
                 double d) throws InvalidArrayIndexException, ArrayIndexOutOfBoundsException

Set the value of an element of the array.

Parameters:

index - index[i] = index along i-th axis, 0 <= index[i] < size(i)

d - value to which element is set

Throws: InvalidArrayIndexException

index[] must be of length 0

Overrides:

set in class doubleArray

 public double get()

Returns the value of the element of the 0-dimensional array, if any.

 public void set(double d)

Sets the value of the element of the 0-dimensional array, if any.

Parameters:

d - value for the element

 public void assign(double d)

Assign a scalar value to all elements of the array.

Parameters:

d - value to be assigned

 public void assign(doubleArray0D a) throws NonconformingArrayException

Assign the values from another zero-dimensional array to this array.

Parameters:

a - array with source value

Throws: NonconformingArrayException

arrays must be of same shape
