Method Detail

getValueAt

double getValueAt(int ix,
                  int iy)

Get the value at the given indexes.

Parameters:

ix - X index

iy - Y index

Returns:

value at the given index

getElementAt

@NotNull
default java.lang.Double getElementAt(int ix,
                                               int iy)

Description copied from interface: TwoDimensionalReadAccess

Get the element at the given indexes.

Specified by:

getElementAt in interface TwoDimensionalReadAccess<java.lang.Double>

Parameters:

ix - index in X direction from 0 (included) to TwoDimensionalReadAccess.sizeX() (excluded)

iy - index in Y direction from 0 (included) to TwoDimensionalReadAccess.sizeY() (excluded)

Returns:

element at the given indexes

subAtX

@NotNull
default OneDimensionalDoubleReadAccess subAtX(int ix)

Description copied from interface: TwoDimensionalReadAccess

Get a 1-dimensional view of the row at the given X index. This is a view, so setting elements will change values in this array.

Specified by:

subAtX in interface TwoDimensionalReadAccess<java.lang.Double>

Parameters:

ix - X index

Returns:

1-dimensional array at ix

subAtY

@NotNull
default OneDimensionalDoubleReadAccess subAtY(int iy)

Description copied from interface: TwoDimensionalReadAccess

Get a 1-dimensional view of the column at the given X index. This is a view, so setting elements will change values in this array.

Specified by:

subAtY in interface TwoDimensionalReadAccess<java.lang.Double>

Parameters:

iy - Y index

Returns:

1-dimensional array at iy

transposed

@NotNull
default TwoDimensionalDoubleReadAccess transposed()

Description copied from interface: TwoDimensionalReadAccess

Get a transposed view of this 2-dimensional read access.

Specified by:

transposed in interface TwoDimensionalReadAccess<java.lang.Double>

Returns:

transposed view where X and Y are interchanged

asBase

@NotNull
default TwoDimensionalDoubleReadAccess.Base asBase()

Get a view of this 2-dimensional access which provides useful defaults for standard object methods.

Specified by:

asBase in interface TwoDimensionalReadAccess<java.lang.Double>

Returns:

base view of this object

singleton

@NotNull
static TwoDimensionalDoubleReadAccess singleton(double singleElement)

Get a 2dimensional double read access for a single element.

Specified by:

singleton in interface TwoDimensionalReadAccess<java.lang.Double>

Parameters:

singleElement - single element

Returns:

2dimensional double read access with size 1 in both directions, containing just the given single element
