Constructor Detail

LongStringConverter

public LongStringConverter(ValueModel<Long> pSubject)

Create a new Long-to-String converter where null is a valid value.

Parameters:

pSubject - the ValueModel holding the original value

LongStringConverter

public LongStringConverter(ValueModel<Long> pSubject,
                   boolean pNullIsValid)

Create a new Long-to-String converter.

Parameters:

pSubject - the ValueModel holding the original value

pNullIsValid - true if we should use null as an alternative value if the conversion fails

Method Detail

convertToNumber

protected Long convertToNumber(String pOwnValue)
                        throws NumberFormatException

convert the own string value to the number. Implement this method to create your number instance, e.g. like return new Integer( ownValue); . If the conversion is not possible, you can throw a NumberFormatException which will be converted into a ConversionException with the correct substitute values.

Specified by:

convertToNumber in class AbstractNumberStringConverter<Long>

Parameters:

pOwnValue - the value as a string

Returns:

the parsed number in its desired class

Throws:

NumberFormatException - if the string value is not parsable into a number
