     * #### getInOutCols  
     scala.Tuple2<String[],String[]> getInOutCols()  
     Returns the input and output column names corresponding in pair.  
     * #### getMissingValue  
     double getMissingValue()  
     * #### getStrategy  
     String getStrategy()  
     * #### missingValue  
     [DoubleParam](../../../../../org/apache/spark/ml/param/DoubleParam.html "class in org.apache.spark.ml.param") missingValue()  
     The placeholder for the missing values. All occurrences of missingValue will be imputed. Note that null values are always treated as missing. Default: Double.NaN  
     Returns:  
     (undocumented)  
     * #### strategy  
     [Param](../../../../../org/apache/spark/ml/param/Param.html "class in org.apache.spark.ml.param")<String> strategy()  
     The imputation strategy. Currently only "mean" and "median" are supported. If "mean", then replace missing values using the mean value of the feature. If "median", then replace missing values using the approximate median value of the feature. If "mode", then replace missing using the most frequent value of the feature. Default: mean  
     Returns:  
     (undocumented)  
     * #### validateAndTransformSchema  
     [StructType](../../../../../org/apache/spark/sql/types/StructType.html "class in org.apache.spark.sql.types") validateAndTransformSchema([StructType](../../../../../org/apache/spark/sql/types/StructType.html "class in org.apache.spark.sql.types") schema)  
     Validates and transforms the input schema.
