  • Method Details

    • convertIndexes

      FieldSet<Integer> convertIndexes(Conversion... conversions)
      Applies a set of Conversion objects over indexes of a record.

      The idiom to define which indexes should have these conversions applies is as follows: 

      
 processor.convertIndexes(Conversions.trim(), Conversions.toUpperCase()).add(2, 5); // applies trim and uppercase conversions to fields in indexes 2 and 5
      Parameters:
      conversions - The sequence of conversions to be executed in a set of field indexes.
      Returns:
      A FieldSet for indexes.

    • convertAll

      void convertAll(Conversion... conversions)
      Applies a set of Conversion objects over all elements of a record
      Parameters:
      conversions - The sequence of conversions to be executed in all elements of a record

    • convertFields

      FieldSet<String> convertFields(Conversion... conversions)
      Applies a set of Conversion objects over fields of a record by name.

      The idiom to define which fields should have these conversions applied is as follows: 

      
 processor.convertFields(Conversions.trim(), Conversions.toUpperCase()).add("name", "position"); // applies trim and uppercase conversions to fields with headers "name" and "position"
      Parameters:
      conversions - The sequence of conversions to be executed in a set of field indexes.
      Returns:
      A FieldSet for field names.

    • convertType

      void convertType(Class<?> type, Conversion... conversions)
      Applies a sequence of conversions over values of a given type. Used for writing.
      Parameters:
      type - the type over which a sequence of conversions should be applied
      conversions - the sequence of conversions to apply over values of the given type.
