Method Details

create

public static LongNdArray create(LongDataBuffer buffer,
 Shape shape)

getLong

public long getLong(long... indices)

Description copied from interface: LongNdArray

Returns the long 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:

LongNdArray matrix = NdArrays.ofLongs(shape(2, 2));  // matrix rank = 2
matrix.getLong(0, 1);  // succeeds, returns 0L
matrix.getLong(0);  // throws IllegalRankException

LongNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
scalar.getLong();  // succeeds, returns 0L

Specified by:

getLong in interface LongNdArray

Parameters:

indices - coordinates of the scalar to resolve

Returns:

value of that scalar

setLong

public LongNdArray setLong(long value,
 long... indices)

Description copied from interface: LongNdArray

Assigns the long 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:

LongNdArray matrix = NdArrays.ofLongs(shape(2, 2));  // matrix rank = 2
matrix.setLong(10L, 0, 1);  // succeeds
matrix.setLong(10L, 0);  // throws IllegalRankException

LongNdArray scalar = matrix.get(0, 1);  // scalar rank = 0
scalar.setLong(10L);  // succeeds

Specified by:

setLong in interface LongNdArray

Parameters:

value - value to assign

indices - coordinates of the scalar to assign

Returns:

this array

copyTo

public LongNdArray copyTo(NdArray<Long> 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 LongNdArray

Specified by:

copyTo in interface NdArray<Long>

Parameters:

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

Returns:

this array

copyTo

public LongNdArray copyTo(LongDataBuffer dst)

Specified by:

copyTo in interface LongNdArray

copyFrom

public LongNdArray copyFrom(LongDataBuffer src)

Specified by:

copyFrom in interface LongNdArray

buffer

protected LongDataBuffer buffer()

Specified by:

buffer in class AbstractDenseNdArray<Long, LongNdArray>

dimensions

public DimensionalSpace dimensions()

shape

public Shape shape()

Specified by:

shape in interface Shaped

Returns:

the shape of this container

scalars

public NdArraySequence<LongNdArray> 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

slowHashCode

protected int slowHashCode()

slowEquals

protected boolean slowEquals(NdArray<?> array)
