Enum SignPolicy

java.lang.Object

java.lang.Enum<SignPolicy>

net.time4j.format.expert.SignPolicy

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<SignPolicy>

public enum SignPolicy
extends java.lang.Enum<SignPolicy>

Determines a suitable strategy for handling numerical signs.

Note: Signs can usually only occur in ISO-8601-context. Therefore Time4J will never process signs in a localized way. That means signs are the ASCII-chars '+' and '-'. A sign precedes the sequence of numerical digits. Localized formats of elements with signs (for example in arab language) require a special ChronoPrinter and ChronoParser.

A parser will only pay attention to this configuration in strict mode.

Enum Constant Summary

Enum Constants

Enum Constant and Description
SHOW_ALWAYS The sign will always be printed.
SHOW_NEVER A sign will never be printed or accepted in parsing.
SHOW_WHEN_BIG_NUMBER A positive sign will be printed if the numerical amount has more digits than specified.
SHOW_WHEN_NEGATIVE A positive sign will never be printed, but a negative sign is always printed.

Enum Constant Detail

SHOW_NEVER

public static final SignPolicy SHOW_NEVER

A sign will never be printed or accepted in parsing.

This setting is the default.

SHOW_WHEN_NEGATIVE

public static final SignPolicy SHOW_WHEN_NEGATIVE

A positive sign will never be printed, but a negative sign is always printed.

This setting is the default for proleptic years in ISO-8601 format if the year numbers have less than four, but not two digits.

SHOW_WHEN_BIG_NUMBER

public static final SignPolicy SHOW_WHEN_BIG_NUMBER

A positive sign will be printed if the numerical amount has more digits than specified.

This setting is the default for proleptic years in ISO-8601-format if the year numbers have more than four digits. Negative signs will always be printed.

SHOW_ALWAYS

public static final SignPolicy SHOW_ALWAYS

The sign will always be printed.

Method Detail

values

public static SignPolicy[] 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 (SignPolicy c : SignPolicy.values())
    System.out.println(c);

Returns:

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

valueOf

public static SignPolicy valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
