| 30 | * YearMonthDay is an immutable partial supporting the year, monthOfYear |
| 31 | * and dayOfMonth fields. |
| 32 | * <p> |
| 33 | * NOTE: This class only supports the three fields listed above. Thus, you |
| 34 | * cannot query the dayOfWeek or centuryOfEra fields for example. |
| 35 | * The new <code>LocalDate</code> class removes this restriction. |
| 36 | * <p> |
| 37 | * Calculations on YearMonthDay are performed using a {@link Chronology}. |
| 38 | * This chronology is set to be in the UTC time zone for all calculations. |
| 39 | * <p> |
| 40 | * Each individual field can be queried in two ways: |
| 41 | * <ul> |
| 42 | * <li><code>getMonthOfYear()</code> |
| 43 | * <li><code>monthOfYear().get()</code> |
| 44 | * </ul> |
| 45 | * The second technique also provides access to other useful methods on the |
| 46 | * field: |
| 47 | * <ul> |
| 48 | * <li>numeric value - <code>monthOfYear().get()</code> |
| 49 | * <li>text value - <code>monthOfYear().getAsText()</code> |
| 50 | * <li>short text value - <code>monthOfYear().getAsShortText()</code> |
| 51 | * <li>maximum/minimum values - <code>monthOfYear().getMaximumValue()</code> |
| 52 | * <li>add/subtract - <code>monthOfYear().addToCopy()</code> |
| 53 | * <li>set - <code>monthOfYear().setCopy()</code> |
| 54 | * </ul> |
| 55 | * <p> |
| 56 | * YearMonthDay is thread-safe and immutable, provided that the Chronology is as well. |
| 57 | * All standard Chronology classes supplied are thread-safe and immutable. |
