Method Detail

getCoordinateArray

ArrayDouble.D3 getCoordinateArray(int timeIndex)
                                  throws IOException,
                                         InvalidRangeException

Get the 3D vertical coordinate array for this time step. Must be in "canonical order" : z, y, x.

Parameters:

timeIndex - the time index. Ignored if !isTimeDependent().

Returns:

vertical coordinate array

Throws:

IOException - problem reading the data

InvalidRangeException - timeIndex out of bounds

getUnitString

String getUnitString()

Get the unit string for the vertical coordinate.

Returns:

unit string

isTimeDependent

boolean isTimeDependent()

Get whether this coordinate is time dependent.

Returns:

true if time dependent

subset

VerticalTransform subset(Range t_range,
                       Range z_range,
                       Range y_range,
                       Range x_range)
                         throws InvalidRangeException

Create a VerticalTransform as a section of an existing VerticalTransform.

Parameters:

t_range - subset the time dimension, or null if you want all of it

z_range - subset the vertical dimension, or null if you want all of it

y_range - subset the y dimension, or null if you want all of it

x_range - subset the x dimension, or null if you want all of it

Returns:

a new VerticalTransform for the given subset

Throws:

InvalidRangeException - if any Range is incompatible with the existing VerticalTransform
