Method Detail

getTransformName

public String getTransformName()

Description copied from interface: VertTransformBuilderIF

Get the Transform name. Typically this is matched on by an attribute in the dataset.

Specified by:

getTransformName in interface VertTransformBuilderIF

Specified by:

getTransformName in class AbstractTransformBuilder

Returns:

name of the transform.

getTransformType

public TransformType getTransformType()

makeCoordinateTransform

public VerticalCT makeCoordinateTransform(NetcdfDataset ds,
                                          AttributeContainer ctv)

Description copied from interface: VertTransformBuilderIF

Make a vertical CoordinateTransform from a Coordinate Transform Variable. A VerticalCT is just a container for the metadata, the real work is in the VerticalTransform

Specified by:

makeCoordinateTransform in interface VertTransformBuilderIF

Parameters:

ds - the containing dataset

ctv - the coordinate transform variable.

Returns:

CoordinateTransform

toString

public String toString()

Overrides:

toString in class Object

makeMathTransform

public VerticalTransform makeMathTransform(NetcdfDataset ds,
                                           Dimension timeDim,
                                           VerticalCT vCT)

Description copied from interface: VertTransformBuilderIF

Make a VerticalTransform. We need to defer making the transform until we've identified the time coordinate dimension.

Specified by:

makeMathTransform in interface VertTransformBuilderIF

Parameters:

ds - the dataset

timeDim - the time dimension

vCT - the vertical coordinate transform

Returns:

ucar.unidata.geoloc.vertical.VerticalTransform math transform
