Constructor Details

DenseNdArray

protected DenseNdArray(DataBuffer<T> buffer,
 Shape shape)

Method Details

wrap

public static <T> NdArray<T> wrap(DataBuffer<T> buffer,
 Shape shape)

copyTo

public NdArray<T> copyTo(NdArray<T> 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.

Parameters:

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

Returns:

this array

buffer

protected DataBuffer<T> buffer()

Specified by:

buffer in class AbstractDenseNdArray<T, NdArray<T>>

dimensions

public DimensionalSpace dimensions()

shape

public Shape shape()

Specified by:

shape in interface Shaped

Returns:

the shape of this container

scalars

public NdArraySequence<NdArray<T>> 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)
