Method Detail

getTransformName

public java.lang.String getTransformName()

Description copied from interface: CoordTransBuilderIF

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

Returns:

name of the transform.

getTransformType

public TransformType getTransformType()

Description copied from interface: CoordTransBuilderIF

Get the Transform Type : Vertical or Projection

Returns:

type of trrasnform

makeCoordinateTransform

public CoordinateTransform makeCoordinateTransform(NetcdfDataset ds,
                                                   Variable ctv)

Description copied from interface: CoordTransBuilderIF

Make a CoordinateTransform from a Coordinate Transform Variable.

Parameters:

ds - the containing dataset

ctv - the coordinate transform variable.

Returns:

CoordinateTransform

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

makeMathTransform

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

Description copied from interface: CoordTransBuilderIF

Make a VerticalTransform. Only implement if you are a TransformType.Vertical. We need to defer making the transform until we've identified the time coordinate dimension.

Specified by:

makeMathTransform in interface CoordTransBuilderIF

Overrides:

makeMathTransform in class AbstractCoordTransBuilder

Parameters:

ds - the dataset

timeDim - the time dimension

vCT - the vertical coordinate transform

Returns:

ucar.unidata.geoloc.vertical.VerticalTransform math transform
