public class CoordinateAxis2D
extends CoordinateAxis

A 2-dimensional numeric Coordinate Axis. Must be invertible meaning, roughly, that if you draw lines connecting the points, none would cross.

Method Detail

builder

public static CoordinateAxis2D.Builder<?> builder()

Get Builder for this class that allows subclassing.

findTimeIndexFromCalendarDate

public int findTimeIndexFromCalendarDate(int run_idx,
                                         CalendarDate want)

getCoordBoundsArray

public ArrayDouble.D3 getCoordBoundsArray()

Only call if isInterval()

Returns:

bounds array pr null if not an interval

getCoordinateAxisTimeHelper

public CoordinateAxisTimeHelper getCoordinateAxisTimeHelper()

getCoordValue

public double getCoordValue(int j,
                            int i)

Get the coordinate value at the i, j index.

Parameters:

i - index 0 (fastest varying, right-most)

j - index 1

Returns:

midpoint.get(j, i).

getCoordValues

public double[] getCoordValues()

Get the coordinate values as a 1D double array, in canonical order.

Returns:

coordinate values

Throws:

UnsupportedOperationException - if !isNumeric()

getCoordValuesArray

public ArrayDouble.D2 getCoordValuesArray()

getEdges

public ArrayDouble.D2 getEdges()

isInterval

public boolean isInterval()

Description copied from class: CoordinateAxis

An interval coordinate consists of two numbers, bound1 and bound2. The coordinate value must lie between them, but otherwise is somewhat arbitrary. If not interval, then it has one number, the coordinate value.

Overrides:

isInterval in class CoordinateAxis

Returns:

true if its an interval coordinate.

makeEdges

public static ArrayDouble.D2 makeEdges(ArrayDouble.D2 midpoints)

Normal case: do something reasonable in deciding on the edges when we have the midpoints of a 2D coordinate.

Parameters:

midpoints - values of midpoints with shape (ny, nx)

Returns:

values of edges with shape (ny+1, nx+1)

makeXEdgesRotated

public static ArrayDouble.D2 makeXEdgesRotated(ArrayDouble.D2 midx)

Experimental: for WRF rotated (NMM "E") Grids

Parameters:

midx - x coordinates of midpoints

Returns:

x coordinates of edges with shape (ny+2, nx+1)

makeYEdgesRotated

public static ArrayDouble.D2 makeYEdgesRotated(ArrayDouble.D2 midy)

Experimental: for WRF rotated (NMM "E") Grids

Parameters:

midy - y coordinates of midpoints

Returns:

y coordinates of edges with shape (ny+2, nx+1)

section

public CoordinateAxis2D section(Range r1,
                                Range r2)
                         throws InvalidRangeException

Create a new CoordinateAxis2D as a section of this CoordinateAxis2D.

Parameters:

r1 - the section on the first index

r2 - the section on the second index

Returns:

a section of this CoordinateAxis2D

Throws:

InvalidRangeException - if specified Ranges are invalid

toBuilder

public CoordinateAxis2D.Builder<?> toBuilder()

Description copied from class: Variable

Turn into a mutable Builder. Can use toBuilder().build() to copy.

Overrides:

toBuilder in class CoordinateAxis
