 Shape shape)

Method Details

create

public static IntNdArray create(IntDataBuffer buffer,
 Shape shape)

getInt

public int getInt(long... indices)

Description copied from interface: IntNdArray

Returns the integer value of the scalar found at the given coordinates.

To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:

IntNdArray matrix = NdArrays.ofInts(shape(2, 2));  // matrix rank = 2
matrix.getInt(0, 1);  // succeeds, returns 0
matrix.getInt(0);  // throws IllegalRankException

IntNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
scalar.getInt();  // succeeds, returns 0

Specified by:

getInt in interface IntNdArray

Parameters:

indices - coordinates of the scalar to resolve

Returns:

value of that scalar

setInt

public IntNdArray setInt(int value,
 long... indices)

Description copied from interface: IntNdArray

Assigns the integer value of the scalar found at the given coordinates.

To access the scalar element, the number of coordinates provided must be equal to the number of dimensions of this array (i.e. its rank). For example:

IntNdArray matrix = NdArrays.ofInts(shape(2, 2));  // matrix rank = 2
matrix.setInt(10, 0, 1);  // succeeds
matrix.setInt(10, 0);  // throws IllegalRankException

IntNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
scalar.setInt(10);  // succeeds

Specified by:

setInt in interface IntNdArray

Parameters:

value - value to assign

indices - coordinates of the scalar to assign

Returns:

this array

copyTo

public IntNdArray copyTo(NdArray<Integer> dst)

Description copied from interface: NdArray

Copy the content of this array to the destination array.

The Shaped.shape() of the destination array must be equal to the shape of this array, or an exception is thrown. After the copy, the content of both arrays can be altered independently, without affecting each other.

Specified by:

copyTo in interface IntNdArray

Specified by:

copyTo in interface NdArray<Integer>

Parameters:

dst - array to receive a copy of the content of this array

Returns:

this array

copyTo

public IntNdArray copyTo(IntDataBuffer dst)

Specified by:

copyTo in interface IntNdArray

copyFrom

public IntNdArray copyFrom(IntDataBuffer src)

Specified by:

copyFrom in interface IntNdArray

buffer

protected IntDataBuffer buffer()

Specified by:

buffer in class AbstractDenseNdArray<Integer, IntNdArray>

dimensions

public DimensionalSpace dimensions()

shape

public Shape shape()

Specified by:

shape in interface Shaped

Returns:

the shape of this container

scalars

public NdArraySequence<IntNdArray> scalars()

Description copied from interface: NdArray

Returns a sequence of all scalars in this array.

This is equivalent to call elements(shape().numDimensions() - 1)

Specified by:

scalars in interface NdArray<T>

Returns:

an NdArray sequence

protected int slowHashCode()

slowEquals

protected boolean slowEquals(NdArray<?> array)
