java.lang.Object

org.knime.base.data.util.DataCellStringMapper

public final class DataCellStringMapper
extends Object

Allow a mapping of arbitrary DataCells to unique, well-behaved strings, for example for usage with external executables that may frown upon parsing arbitrary strings. Keeps two maps for each direction (DataCell <-> String) and creates new, unique Strings for unknown DataCells.
