Enum Class SignStyle

java.lang.Object

java.lang.Enum<SignStyle>

java.time.format.SignStyle

All Implemented Interfaces:

Serializable, Comparable<SignStyle>, Constable

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

Nested Class Summary

Nested classes/interfaces declared in class Enum

Enum.EnumDesc<E>

Modifier and Type	Class	Description
static final class	Enum.EnumDesc<E extends Enum<E>>	A nominal descriptor for an enum constant.

Enum Constant Summary

Enum Constants

Enum Constant	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.

Method Summary

Modifier and Type	Method	Description
static SignStyle	valueOf(String name)	Returns the enum constant of this class with the specified name.
static SignStyle[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Methods declared in class Enum

clone, compareTo, describeConstable, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

Modifier and Type	Method	Description
protected final Object	clone()	Throws CloneNotSupportedException.
final int	compareTo(SignStyle o)	Compares this enum with the specified object for order.
final Optional<Enum.EnumDesc<SignStyle>>	describeConstable()	Returns an enum descriptor EnumDesc for this instance, if one can be constructed, or an empty Optional if one cannot be.
final boolean	equals(Object other)	Returns true if the specified object is equal to this enum constant.
protected final void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. Finalization has been deprecated for removal.
final Class<SignStyle>	getDeclaringClass()	Returns the Class object corresponding to this enum constant's enum type.
final int	hashCode()	Returns a hash code for this enum constant.
final String	name()	Returns the name of this enum constant, exactly as declared in its enum declaration.
final int	ordinal()	Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero).
String	toString()	Returns the name of this enum constant, as contained in the declaration.
static <T extends Enum<T>> T	valueOf(Class<T> enumClass, String name)	Returns the enum constant of the specified enum class with the specified name.

Methods declared in class Object

getClass, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Enum Constant Details

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.

Method Details

values

public static SignStyle[] values()

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

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static SignStyle valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
