transform

public File transform(File target,
             File outputDir,
             String format,
             String dataFile,
             int index)
               throws TransformException

Description copied from interface: ProductTransformer

Transform a single target.

Specified by:

transform in interface ProductTransformer

Specified by:

transform in class DefaultTransformer

Parameters:

target - file specification to the PDS label.

outputDir - directory where the output file will be written.

format - Valid format file type.

dataFile - Tells the tool which data file to transform. If this argument is an empty string, the default is to transform the first data file found in the label.

Returns:

The resulting output file.

Throws:

TransformException - If an error occurred during the transformation process.

transformAll

public List<File> transformAll(File target,
                      File outputDir,
                      String format)
                        throws TransformException

target - file specification to the PDS label.

outputDir - directory where the output file will be written.

format - Valid format file type.

Returns:

The resulting output files.
