SignStyle

  • SignStyle is an enum used to control the formatting of positive/negative signs of numbers in Java's date-time API.

  • It provides five different styles: ALWAYS, EXCEEDS_PAD, NEVER, NORMAL, and NOT_NEGATIVE, each with specific rules for outputting and parsing signs.

  • DateTimeFormatterBuilder utilizes SignStyle for customization during the formatting process.

  • SignStyle inherits methods from Enum, Object, and Comparable for object comparison, manipulation, and information retrieval.

  • Each SignStyle constant dictates how signs are handled during both strict and lenient parsing scenarios.

public final 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.

Inherited Method Summary

Enum Values

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.

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.

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.

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.

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.
