All Implemented Interfaces:

ParameterConverters.ParameterConverter<String,Number>

Enclosing class:

ParameterConverters

public static class ParameterConverters.NumberConverter
extends ParameterConverters.FromStringParameterConverter<Number>

Converts values to numbers, supporting any subclass of Number (including generic Number type), and it unboxed counterpart, using a NumberFormat to parse to a Number and to convert it to a specific number type:

• Byte, byte: Number.byteValue()
• Short, short: Number.shortValue()
• Integer, int: Number.intValue()
• Float, float: Number.floatValue()
• Long, long: Number.longValue()
• Double, double: Number.doubleValue()
• BigInteger: BigInteger.valueOf(long)
• BigDecimal: BigDecimal.valueOf(double)

If no number format is provided, it defaults to NumberFormat.getInstance().

The localized instance NumberFormat.getInstance(Locale) can be used to convert numbers in specific locales.
