Class ParseBigDecimal

java.lang.Object

org.supercsv.cellprocessor.CellProcessorAdaptor

org.supercsv.cellprocessor.ParseBigDecimal

All Implemented Interfaces:

CellProcessor, StringCellProcessor

public class ParseBigDecimal
extends CellProcessorAdaptor
implements StringCellProcessor

Convert a String to a BigDecimal. It uses the String constructor of BigDecimal (new BigDecimal("0.1")) as it yields predictable results (see BigDecimal).

If the data uses a character other than "." as a decimal separator (France uses "," for example), then use the constructor that accepts a DecimalFormatSymbols object, as it will convert the character to a "." before creating the BigDecimal.

Constructor and Description
ParseBigDecimal() Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal.
ParseBigDecimal(CellProcessor next) Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal then calls the next processor in the chain.
ParseBigDecimal(DecimalFormatSymbols symbols) Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal using the supplied DecimalFormatSymbols object to convert any decimal separator to a "." before creating the BigDecimal.
ParseBigDecimal(DecimalFormatSymbols symbols, CellProcessor next) Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal using the supplied DecimalFormatSymbols object to convert any decimal separator to a "." before creating the BigDecimal, then calls the next processor in the chain.

Constructor Detail

ParseBigDecimal

public ParseBigDecimal()

Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal.

ParseBigDecimal

public ParseBigDecimal(DecimalFormatSymbols symbols)

Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal using the supplied DecimalFormatSymbols object to convert any decimal separator to a "." before creating the BigDecimal.

Parameters:

symbols - the decimal format symbols, containing the decimal separator

Throws:

NullPointerException - if symbols is null

ParseBigDecimal

public ParseBigDecimal(CellProcessor next)

Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal then calls the next processor in the chain.

Parameters:

next - the next processor in the chain

Throws:

NullPointerException - if next is null

ParseBigDecimal

public ParseBigDecimal(DecimalFormatSymbols symbols,
               CellProcessor next)

Constructs a new ParseBigDecimal processor, which converts a String to a BigDecimal using the supplied DecimalFormatSymbols object to convert any decimal separator to a "." before creating the BigDecimal, then calls the next processor in the chain.

Parameters:

symbols - the decimal format symbols, containing the decimal separator

next - the next processor in the chain

Throws:

NullPointerException - if symbols or next is null

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

Throws:

SuperCsvCellProcessorException - if value is null, isn't a String, or can't be parsed as a BigDecimal
