Class Summary
AbstractMany2OneCellFactory  
BinaryCellFactory Cell with value = 1 matches, others don't.
Many2OneColNodeDialog NodeDialog for the "Many2One" Node.
Many2OneColNodeFactory NodeFactory for the "BayesianPredictor" Node.
Many2OneColNodeModel  
MinMaxCellFactory  
One2ManyCellFactory Maps several original nominal columns to their possible values, creates a column for every possible value and when the rows are processed the value is set to 1 if the original column contains this value and to 0 otherwise.
One2ManyColNodeDialog  
One2ManyColNodeFactory  
One2ManyColNodeModel This node converts one column to many columns, such that each possible value becomes an extra column with the value 1 if the row contains this value in the original column and 0 otherwise.
RegExpCellFactory  
 

Enum Summary
Many2OneColNodeModel.IncludeMethod Possible methods to let a column match.
 

Package org.knime.base.node.preproc.columnTrans Description

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 ColumnRearranger class to append the result columns to the input table. The ColumnRearranger is fed by the different factory classes which implement the CellFactory interface.
