Contains the implementation of a node which writes the content of a data table into an ARFF file. ARFF files are ASCII data files. They consist of a header, specifying the structure and format of the data, and a data section which contains the actual data vectors. The writer creates standard ARFF files, sparse ARFF format is not supported yet. There is code in there for sparse file support, but as the reader as of now cannot read sparse files, we don't create them either.
See the org.knime.base.node.io.arffreader package for a detailed ARFF format description.
