| 30 | * <p>FastDateFormat is a fast and thread-safe version of | |
| 31 | * {@link java.text.SimpleDateFormat}.</p> | |
| 32 | * | |
| 33 | * <p>This class can be used as a direct replacement to | |
| 34 | * {@code SimpleDateFormat} in most formatting and parsing situations. | |
| 35 | * This class is especially useful in multi-threaded server environments. | |
| 36 | * {@code SimpleDateFormat} is not thread-safe in any JDK version, | |
| 37 | * nor will it be as Sun have closed the bug/RFE. | |
| 38 | * </p> | |
| 39 | * | |
| 40 | * <p>All patterns are compatible with | |
| 41 | * SimpleDateFormat (except time zones and some year patterns - see below).</p> | |
| 42 | * | |
| 43 | * <p>Since 3.2, FastDateFormat supports parsing as well as printing.</p> | |
| 44 | * | |
| 45 | * <p>Java 1.4 introduced a new pattern letter, {@code 'Z'}, to represent | |
| 46 | * time zones in RFC822 format (eg. {@code +0800} or {@code -1100}). | |
| 47 | * This pattern letter can be used here (on all JDK versions).</p> | |
| 48 | * | |
| 49 | * <p>In addition, the pattern {@code 'ZZ'} has been made to represent | |
| 50 | * ISO8601 full format time zones (eg. {@code +08:00} or {@code -11:00}). | |
| 51 | * This introduces a minor incompatibility with Java 1.4, but at a gain of | |
| 52 | * useful functionality.</p> | |
| 53 | * | |
| 54 | * <p>Javadoc cites for the year pattern: <i>For formatting, if the number of | |
| 55 | * pattern letters is 2, the year is truncated to 2 digits; otherwise it is | |
| 56 | * interpreted as a number.</i> Starting with Java 1.7 a pattern of 'Y' or | |
| 57 | * 'YYY' will be formatted as '2003', while it was '03' in former Java | |
| 58 | * versions. FastDateFormat implements the behavior of Java 7.</p> | |
| 59 | * | |
| 60 | * @since 2.0 | |
