class TextPreprocessor extends Transformer with HasInputCol with HasOutputCol with Wrappable with ComplexParamsWritable with BasicLogging

TextPreprocessor takes a dataframe and a dictionary that maps (text -> replacement text), scans each cell in the input col and replaces all substring matches with the corresponding value. Priority is given to longer keys and from left to right.
