Method Summary

Modifier and Type	Method	Description
void	convertAll(Conversion... conversions)	Applies a set of Conversion objects over all elements of a record
FieldSet<java.lang.String>	convertFields(Conversion... conversions)	Applies a set of Conversion objects over fields of a record by name.

void	convertType(java.lang.Class<?> type, Conversion... conversions)	Applies a sequence of conversions over values of a given type.

Method Detail

convertIndexes

FieldSet<java.lang.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<java.lang.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(java.lang.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.
