| 23 | * <p><b>Short Validation</b> and Conversion routines (<code>java.lang.Short</code>).</p> | |
| 24 | * | |
| 25 | * <p>This validator provides a number of methods for | |
| 26 | * validating/converting a <code>String</code> value to | |
| 27 | * a <code>Short</code> using <code>java.text.NumberFormat</code> | |
| 28 | * to parse either:</p> | |
| 29 | * <ul> | |
| 30 | * <li>using the default format for the default <code>Locale</code></li> | |
| 31 | * <li>using a specified pattern with the default <code>Locale</code></li> | |
| 32 | * <li>using the default format for a specified <code>Locale</code></li> | |
| 33 | * <li>using a specified pattern with a specified <code>Locale</code></li> | |
| 34 | * </ul> | |
| 35 | * | |
| 36 | * <p>Use one of the <code>isValid()</code> methods to just validate or | |
| 37 | * one of the <code>validate()</code> methods to validate and receive a | |
| 38 | * <i>converted</i> <code>Short</code> value.</p> | |
| 39 | * | |
| 40 | * <p>Once a value has been successfully converted the following | |
| 41 | * methods can be used to perform minimum, maximum and range checks:</p> | |
| 42 | * <ul> | |
| 43 | * <li><code>minValue()</code> checks whether the value is greater | |
| 44 | * than or equal to a specified minimum.</li> | |
| 45 | * <li><code>maxValue()</code> checks whether the value is less | |
| 46 | * than or equal to a specified maximum.</li> | |
| 47 | * <li><code>isInRange()</code> checks whether the value is within | |
| 48 | * a specified range of values.</li> | |
| 49 | * </ul> | |
| 50 | * | |
| 51 | * <p>So that the same mechanism used for parsing an <i>input</i> value | |
| 52 | * for validation can be used to format <i>output</i>, corresponding | |
| 53 | * <code>format()</code> methods are also provided. That is you can | |
| 54 | * format either:</p> | |
| 55 | * <ul> | |
| 56 | * <li>using the default format for the default <code>Locale</code></li> | |
| 57 | * <li>using a specified pattern with the default <code>Locale</code></li> | |
| 58 | * <li>using the default format for a specified <code>Locale</code></li> | |
| 59 | * <li>using a specified pattern with a specified <code>Locale</code></li> | |
| 60 | * </ul> | |
