    • map

      public ColumnMappers.Builder map(String fullyQualifiedColumnNames, ColumnMapper mapper)
      Set a mapping function for the columns with fully-qualified names that match the given comma-separated list of regular expression patterns.
      Parameters:
      fullyQualifiedColumnNames - the comma-separated list of fully-qualified column names; may not be null
      mapper - the column mapping function that will be used to map actual values into values used in the output record; null if an existing mapping function should be removed
      Returns:
      this object so that methods can be chained together; never null
