| 34 | /** | |
| 35 | * This is an extension for evaluating Time expressions in the XML Policy. | |
| 36 | * | |
| 37 | * <p>The Policy must contain Const values of type "Time". The values must | |
| 38 | * conform to the | |
| 39 | * following syntax: "ccyy-mm-ddThh:mm:ss" (like in Validity elements in XML | |
| 40 | * Policy). Thus | |
| 41 | * the time can be specified up to the seconds. | |
| 42 | * The year should always have 4 digits. Other fields do not need to have 2 | |
| 43 | * digits, if they represent | |
| 44 | * numbers less than 10. "*" asterisc can be used as a wildcard to represent | |
| 45 | * "any value" at that position. Trailing fields can be omitted and their | |
| 46 | * values will be considered 0. | |
| 47 | * | |
| 48 | * <p>Examples: | |
| 49 | * <p><code><Constant Type="Time" Value="*-*-*T8:20" /></code> | |
| 50 | * <p>The example matches 08:20:00 in the morning any day | |
| 51 | * <p><code><Constant Type="Time" Value="*-*-*T8:20:*" /></code> | |
| 52 | * <p>The above matches any second after 08:20:00 and before 08:21:00 in the | |
| 53 | * morning any day. This is | |
| 54 | * different from the above example in that it matches ANY second, i.e. the | |
| 55 | * whole minute up to 8:21, whilst | |
| 56 | * the previous example specifies exact time of day (8:20:00). | |
| 57 | * <p><code><Constant Type="Time" Value="*-1-*T20" /></code> | |
| 58 | * <p>This example matches 8pm any day throughout January. | |
| 59 | * <p><code><Constant Type="Time" Value="*-1" /></code> | |
| 60 | * <p>This example matches midnight of every 1st of January. | |
| 61 | * | |
| 62 | * <p>The extension has been provided in PBA v1.1. | |
