Method Detail

convert

public Byte convert(String input,
           Class<? extends Byte> targetType,
           Collection<ValidationError> errors)

Converts a String to a Byte in accordance with the rules laid out in the class level javadoc.

Specified by:

convert in interface TypeConverter<Byte>

Parameters:

input - the String being converted

targetType - the Class representing the type of the property to which the return value of the conversion will be assigned. In many cases this can be ignored as converters will return a single type more often than not.

errors - an empty collection of validation errors that should be populated by the converter for any errors that occur during validation that are user input related.

Returns:

T an instance of the converted type, or null if the input cannot be converted

getNumberFormats

protected NumberFormat[] getNumberFormats()

Overridden to return integer instances instead.

Overrides:

getNumberFormats in class NumberTypeConverterSupport

Returns:

one or more NumberFormats to use in parsing numbers
