Method Detail

registerTransform

public static void registerTransform(String transformName,
                                     Class c)

Register a class that implements a Coordinate Transform.

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 a Coordinate Transform.

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 a Coordinate Transform.

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.

makeCoordinateTransform

public static CoordinateTransform makeCoordinateTransform(NetcdfDataset ds,
                                                          AttributeContainer ctv,
                                                          Formatter parseInfo,
                                                          Formatter errInfo)

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

Parameters:

ds - enclosing dataset, only used for vertical transforms

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

parseInfo - pass back information about the parsing.

errInfo - pass back error information.

Returns:

CoordinateTransform, or null if failure.

makeDummyTransformVariable

public static VariableDS makeDummyTransformVariable(NetcdfDataset ds,
                                                    CoordinateTransform ct)

Create a "dummy" Coordinate Transform Variable based on the given CoordinateTransform. This creates a scalar Variable with dummy data, and adds the Parameters of the CoordinateTransform as attributes.

Parameters:

ds - for this dataset

ct - based on the CoordinateTransform

Returns:

the Coordinate Transform Variable. You must add it to the dataset.

makeProjection

public static ProjectionImpl makeProjection(CoverageTransform gct,
                                            Formatter errInfo)

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

Parameters:

errInfo - pass back error information.

Returns:

CoordinateTransform, or null if failure.
