Class DMinMax

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.constraint.DMinMax

All Implemented Interfaces:

CellProcessor, StringCellProcessor

public class DMinMax
extends CellProcessorAdaptor
implements StringCellProcessor

Converts the input data to a Double and ensures that number is within a specified numeric range (inclusive). If the data has no upper bound (or lower bound), you should use either of MIN or MAX constants provided in the class.

Constructor Summary

Constructors

Constructor and Description
DMinMax(double min, double max) Constructs a new DMinMax processor, which converts the input to a Double and ensures the value is between the supplied min and max values.
DMinMax(double min, double max, DoubleCellProcessor next) Constructs a new DMinMax processor, which converts the input to a Double, ensures the value is between the supplied min and max values, then calls the next processor in the chain.

Constructor Detail

DMinMax

public DMinMax(double min,
               double max)

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

Parameters:

min - the minimum value (inclusive)

max - the maximum value (inclusive)

Throws:

java.lang.IllegalArgumentException - if max < min

DMinMax

public DMinMax(double min,
               double max,
               DoubleCellProcessor next)

Constructs a new DMinMax processor, which converts the input to a Double, 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:

java.lang.IllegalArgumentException - if max < min

java.lang.NullPointerException - if next is null

Method Detail

execute

public java.lang.Object execute(java.lang.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

Throws:

SuperCsvCellProcessorException - if value is null or can't be parsed as a Double

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