Enum SignStyle

All Implemented Interfaces:
Serializable, Comparable<SignStyle>

public enum SignStyle
extends Enum<SignStyle>

Enumeration of ways to handle the positive/negative sign.

The formatting engine allows the positive and negative signs of numbers to be controlled using this enum. See DateTimeFormatterBuilder for usage.

Implementation Requirements:
This is an immutable and thread-safe enum.
Since:
1.8

Enum Constants

Enum Constant and Description
ALWAYS

Style to always output the sign, where zero will output '+'.
EXCEEDS_PAD

Style to always output the sign if the value exceeds the pad width.
NEVER

Style to never output sign, only outputting the absolute value.
NORMAL

Style to output the sign only if the value is negative.
NOT_NEGATIVE

Style to block negative values, throwing an exception on printing.

Methods

Modifier and Type Method and Description
static SignStyle valueOf(String name)

Returns the enum constant of this type with the specified name.
static SignStyle[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constants

NORMAL

public static final SignStyle NORMAL

Style to output the sign only if the value is negative.

In strict parsing, the negative sign will be accepted and the positive sign rejected. In lenient parsing, any sign will be accepted.

ALWAYS

public static final SignStyle ALWAYS

Style to always output the sign, where zero will output '+'.

In strict parsing, the absence of a sign will be rejected. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

NEVER

public static final SignStyle NEVER

Style to never output sign, only outputting the absolute value.

In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

NOT_NEGATIVE

public static final SignStyle NOT_NEGATIVE

Style to block negative values, throwing an exception on printing.

In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

EXCEEDS_PAD

public static final SignStyle EXCEEDS_PAD

Style to always output the sign if the value exceeds the pad width. A negative value will always output the '-' sign.

In strict parsing, the sign will be rejected unless the pad width is exceeded. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

Methods

values

public static SignStyle[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 

for (SignStyle c : SignStyle.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static SignStyle valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
IllegalArgumentException - if this enum type has no constant with the specified name
NullPointerException - if the argument is null
