ExpressionTransformation Class

The expression transformation allows adding, replacing, and/or deleting columns. This is generally done by supplying a column selection to work on, and, in the first two cases, also providing an expression, name and, optionally, a formatter. The column selection can be either a fixed set of columns, or a column search expression which will be reevaluated each time the transformation is executed. Use the column name symbol to refer to the columns selected in expressions.
