Method Detail

registerTransform

public static void registerTransform(String transformName,
                                     Class<?> c)

Register a class that implements HorizTransformBuilderIF

Parameters:

transformName - name of transform. This name is used in the datasets to identify the transform, eg CF names.

c - class that implements CoordTransBuilderIF.

registerTransform

public static void registerTransform(String transformName,
                                     String className)
                              throws ClassNotFoundException

Register a class that implements HorizTransformBuilderIF.

Parameters:

transformName - name of transform. This name is used in the datasets to identify the transform, eg CF names.

className - name of class that implements CoordTransBuilderIF.

Throws:

ClassNotFoundException - if Class.forName( className) fails

registerTransformMaybe

public static void registerTransformMaybe(String transformName,
                                          String className)

Register a class that implements HorizTransformBuilderIF.

Parameters:

transformName - name of transform. This name is used in the datasets to identify the transform, eg CF names.

className - name of class that implements CoordTransBuilderIF.

makeProjection

@Nullable
public static Projection makeProjection(AttributeContainer ctv,
                                                   String geoUnits,
                                                   Formatter parseInfo)

Make a CoordinateTransform object from the parameters in a Coordinate Transform Variable, using an intrinsic or registered CoordTransBuilder.

Parameters:

ctv - the Coordinate Transform Variable - container for the transform parameters

parseInfo - pass back information about the parsing.

Returns:

CoordinateTransform, or null if failure.
