public class RealNDArrayMaskView<T extends Number>
extends AbstractNDArrayMaskView<T,T>
implements RealNDArray<T>

A view for an NDArray holding real values that selects values based on a specified mask. When mask(...) is called for a real NDArray, an instance of this class is returned.

Method Detail

copyFrom

public NDArray<T> copyFrom(NDArray<?> array)

Description copied from interface: NDArray

Updates this NDArray with the elements of the NDArray given as parameter.

Note: the parameter NDArray must have the same shape and this NDArray!

Specified by:

copyFrom in interface NDArray<T extends Number>

Parameters:

array - NDArray from which values are copied to this NDArray

Returns:

this NDArray

set

public void set(Number value,
                int linearIndex)

Description copied from interface: NDArray

Sets the value of an element specified by linear indexing.

Linear indexing: It selects the ith element using the column-major iteration order that linearly spans the entire array. in its particular dimension.

Negative indexing is supported, e.g. -1 refers to the last element, -2 refers to the item before the last one, etc.

Specified by:

set in interface NDArray<T extends Number>

Overrides:

set in class AbstractNDArray<T extends Number,T extends Number>

Parameters:

value - value to be assigned

linearIndex - linear coordinates

set

public void set(Number value,
                int... indices)

Description copied from interface: NDArray

Sets the value of an element specified by cartesian indexing.

Cartesian indexing: The ordinary way to index into an N-dimensional array is to use exactly N indices; each index selects the position(s) in its particular dimension.

Negative indexing is supported, e.g. assuming a 3×4 NDArray, index [2,-1] equals to [2,3], and [-1,-3] is an equivalent of [2,1].

Specified by:

set in interface NDArray<T extends Number>

Overrides:

set in class AbstractNDArray<T extends Number,T extends Number>

Parameters:

value - value to be assigned

indices - cartesian coordinates
