Class StrMinMax

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.constraint.StrMinMax

All Implemented Interfaces:

CellProcessor, StringCellProcessor

public class StrMinMax
extends CellProcessorAdaptor
implements StringCellProcessor

This constraint ensures that the input data has a string length between the supplied min and max values (both inclusive). Should the input be anything different from a String, it will be converted to a string using the input's toString() method.

Constructor Detail

StrMinMax

public StrMinMax(long min,
                 long max)

Constructs a new StrMinMax processor, which ensures that the input data has a string length between the supplied min and max values (both inclusive).

Parameters:

min - the minimum String length

max - the maximum String length

Throws:

IllegalArgumentException - if max < min, or min is < 0

StrMinMax

public StrMinMax(long min,
                 long max,
                 CellProcessor next)

Constructs a new StrMinMax processor, which ensures that the input data has a string length between the supplied min and max values (both inclusive), then calls the next processor in the chain.

Parameters:

min - the minimum String length

max - the maximum String length

next - the next processor in the chain

Throws:

NullPointerException - if next is null

IllegalArgumentException - if max < min, or min is < 0

Method Detail

execute

public Object execute(Object value,
                      CsvContext context)

This method is invoked by the framework when the processor needs to process data or check constraints.

Specified by:

execute in interface CellProcessor

Parameters:

value - the value to be processed

context - the CSV context

Returns:

the result of cell processor execution

Throws:

SuperCsvCellProcessorException - if value is null

SuperCsvConstraintViolationException - if length < min or length > max
