Enum DateFormats

java.lang.Object

java.lang.Enum<DateFormats>

org.refcodes.time.DateFormats

All Implemented Interfaces:

Serializable, Comparable<DateFormats>

public enum DateFormats
extends Enum<DateFormats>

The DateFormats represent sets of DateFormat definitions. Such a set is most useful to parse back a String into a Date when there are multiple possible String representations. E.g. a cookie's date representation might be either as defined by the DateFormat.NETSCAPE_COOKIE_DATE_FORMAT or by the DateFormat.ALTERNATE_COOKIE_DATE_FORMAT.

Method Detail

values

public static DateFormats[] values()

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

Returns:

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

valueOf

public static DateFormats 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

getDateFormats

public DateTimeFormatter[] getDateFormats()

Gets the date formats.

Returns:

the date formats

toDate

public Date toDate(String aDateString)
            throws DateTimeException

Creates a date from the provided String using the date formats as retrieved by the getDateFormats() method. If one date format fails, then the next one is used to parse the date text.
