| 40 | * Factory that creates complex instances of DateTimeFormatter via method calls. |
| 41 | * <p> |
| 42 | * Datetime formatting is performed by the {@link DateTimeFormatter} class. |
| 43 | * Three classes provide factory methods to create formatters, and this is one. |
| 44 | * The others are {@link DateTimeFormat} and {@link ISODateTimeFormat}. |
| 45 | * <p> |
| 46 | * DateTimeFormatterBuilder is used for constructing formatters which are then |
| 47 | * used to print or parse. The formatters are built by appending specific fields |
| 48 | * or other formatters to an instance of this builder. |
| 49 | * <p> |
| 50 | * For example, a formatter that prints month and year, like "January 1970", |
| 51 | * can be constructed as follows: |
| 52 | * <p> |
| 53 | * <pre> |
| 54 | * DateTimeFormatter monthAndYear = new DateTimeFormatterBuilder() |
| 55 | * .appendMonthOfYearText() |
| 56 | * .appendLiteral(' ') |
| 57 | * .appendYear(4, 4) |
| 58 | * .toFormatter(); |
| 59 | * </pre> |
| 60 | * <p> |
| 61 | * DateTimeFormatterBuilder itself is mutable and not thread-safe, but the |
| 62 | * formatters that it builds are thread-safe and immutable. |
