This package contains the classes of the Many2One and One2Many column transformation nodes. The One2Many node creates for each distinct value of the selected column(s) a new column with the value as name. The Many2One node creates a new column from multiple columns with the name of the column which matches the include criteria as value.

Both nodes use the {@link org.knime.core.data.container.ColumnRearranger} class to append the result columns to the input table. The ColumnRearranger is fed by the different factory classes which implement the {@link org.knime.core.data.container.CellFactory} interface.
