Method Detail

getCoordinateArray

public abstract ArrayDouble.D3 getCoordinateArray(int timeIndex)
                                           throws java.io.IOException,
                                                  InvalidRangeException

Get the 3D vertical coordinate array for this time step.

Specified by:

getCoordinateArray in interface VerticalTransform

Parameters:

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

Returns:

vertical coordinate array

Throws:

InvalidRangeException - _more_

java.io.IOException - problem reading the data

getCoordinateArray1D

public abstract ArrayDouble.D1 getCoordinateArray1D(int timeIndex,
                                                    int xIndex,
                                                    int yIndex)
                                             throws java.io.IOException,
                                                    InvalidRangeException

Get the 1D vertical coordinate array for this time step and point

Specified by:

getCoordinateArray1D in interface VerticalTransform

Parameters:

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

xIndex - the x index

yIndex - the y index

Returns:

vertical coordinate array

Throws:

java.io.IOException - problem reading data

InvalidRangeException - _more_

getUnitString

public java.lang.String getUnitString()

Get the unit string for the vertical coordinate.

Specified by:

getUnitString in interface VerticalTransform

Returns:

unit string

isTimeDependent

public boolean isTimeDependent()

Get whether this coordinate is time dependent.

Specified by:

isTimeDependent in interface VerticalTransform

Returns:

true if time dependent

getTimeDimension

protected Dimension getTimeDimension()

Get the time Dimension

Returns:

time Dimension

readArray

protected Array readArray(Variable v,
                          int timeIndex)
                   throws java.io.IOException,
                          InvalidRangeException

Read the data Array from the variable, at the specified time index if applicable. If the variable does not have a time dimension, the data array will have the same rank as the Variable. If the variable has a time dimension, the data array will have rank-1.

Parameters:

v - variable to read

timeIndex - time index, ignored if !isTimeDependent()

Returns:

Array from the variable at that time index

Throws:

java.io.IOException - problem reading data

InvalidRangeException - _more_

subset

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

Create a subset of this VerticalTransform.

Specified by:

subset in interface 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
