Package org.supercsv.cellprocessor.constraint

Class LMinMax

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.constraint.LMinMax

All Implemented Interfaces:

CellProcessor, StringCellProcessor

public class LMinMax
extends CellProcessorAdaptor
implements StringCellProcessor

Converts the input data to a Long and and ensures the value is between the supplied min and max values (inclusive). If the data has no upper or lower bound, you should use either of MIN or MAX constants provided in the class.

Constructor Detail

LMinMax

public LMinMax(long min,
               long max)

Constructs a new LMinMax processor, which converts the input data to a Long and and ensures the value is between the supplied min and max values.

Parameters:

min - the minimum value (inclusive)

max - the maximum value (inclusive)

Throws:

IllegalArgumentException - if max < min

LMinMax

public LMinMax(long min,
               long max,
               LongCellProcessor next)

Constructs a new LMinMax processor, which converts the input data to a Long and and ensures the value is between the supplied min and max values, then calls the next processor in the chain.

Parameters:

min - the minimum value (inclusive)

max - the maximum value (inclusive)

next - the next processor in the chain

Throws:

NullPointerException - if next is null

IllegalArgumentException - if max < min

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 or can't be parsed as a Long

SuperCsvConstraintViolationException - if value, or doesn't lie between min and max (inclusive)
