Class IsIncludedIn

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.constraint.IsIncludedIn

All Implemented Interfaces:

BoolCellProcessor, CellProcessor, DateCellProcessor, DoubleCellProcessor, LongCellProcessor, StringCellProcessor

public class IsIncludedIn
extends CellProcessorAdaptor
implements BoolCellProcessor, DateCellProcessor, DoubleCellProcessor, LongCellProcessor, StringCellProcessor

This processor ensures that the input value belongs to a specific set of (unchangeable) values. If you want to check if the value is an element of a (possibly changing) Collection, then use IsElementOf instead.

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 value isn't one of the possible values
