Method Detail

parseInt

public static int parseInt(String input)

Parse an integer using all allowed embellishments.

Parameters:

input -

Returns:

parseIntWrapper

@Nullable
public static Integer parseIntWrapper(String input)

parseLong

public static long parseLong(String input)

parseLongWrapper

@Nullable
public static Long parseLongWrapper(String input)

parseDoubleWrapper

@Nullable
public static Double parseDoubleWrapper(String input,
                                                  int scale,
                                                  NumericPresentation np)

parseBigDecimal

@Nullable
public static BigDecimal parseBigDecimal(String input,
                                                   int scale,
                                                   NumericPresentation np)

parseNumber

@Deprecated
 @Nullable
public static <T> T parseNumber(Class<T> type,
                                                       String input)

Deprecated.

DEPRECATED: This method wrongly assumes the scale of the number parsed - use parseNumber(Class, String, int). Parse any supported numeric wrapper type. In case that any specific scale must be used, use other method parseNumber(Class, String, int, NumericPresentation)

Type Parameters:

T -

Parameters:

type - In case of decimal types, it uses scale defined by DEFAULT_FRACTION_DIGITS.

input -

Returns:

parseNumber

@Nullable
public static <T> T parseNumber(Class<T> type,
                                          String input,
                                          int scale)

Parse any supported numeric wrapper type. In case that any specific scale must be used, use other method parseNumber(Class, String, int, NumericPresentation)

Type Parameters:

T -

Parameters:

type - In case of decimal types, it uses scale defined by DEFAULT_FRACTION_DIGITS.

input -

Returns:

parseNumber

@Nullable
public static <T> T parseNumber(Class<T> type,
                                          String input,
                                          int scale,
                                          NumericPresentation np)

Parse any supported numeric wrapper type.

Type Parameters:

T -

Parameters:

type -

input -

scale - Integer based types can be used only with scale 0 -> no decimal places allowed here.

np -

Returns:

renderNumber

@Nonnull
public static String renderNumber(Number v,
                                           NumericPresentation np,
                                           int scale)

public static <T extends Number> IConverter<T> createNumberConverter(Class<T> type,
                                                                     NumericPresentation np,
