/** |

|
|
|
* Objects of this type represent all that is known about a certain user-provided |
20
|
|
|
* data value, especially its various representations as strings, tooltips, |
21
|
|
|
* numbers, etc. Objects can be created as "emtpy" containers of a certain type, |
22
|
|
|
* but are then usually filled with data to present one particular data value. |
23
|
|
|
* |
24
|
|
|
* Data values have two chief representation forms: the user-facing syntax and the |
25
|
|
|
* internal representation. In user syntax, every value is (necessarily) a single |
26
|
|
|
* string, however complex the value is. For example, a string such as "Help:editing" |
27
|
|
|
* may represent a wiki page called "Editing" in the namespace for "Help". The |
28
|
|
|
* internal representation may be any numerical array of strings and numbers. In the |
29
|
|
|
* example, it might be array("Editing",12), where 12 is the number used for identifying |
30
|
|
|
* the namespace "Help:". Of course, the internal representation could also use a single |
31
|
|
|
* string value, such as in array("Help:Editing"), but this might be less useful for |
32
|
|
|
* certain operations (e.g. filterng by namespace). Moreover, all values that are |
33
|
|
|
* restored from the database are given in the internal format, so it wise to choose a |
34
|
|
|
* format that allows for very fast and easy processing without unnecessary parsing. |
35
|
|
|
* |
36
|
|
|
* The main functions of data value objects are: |
37
|
|
|
* - setUserValue() which triggers parseUserValue() to process a user-level string. |
38
|
|
|
* |
39
|
|
|
* In addition, there are a number of get-functions that provide useful output versions |
40
|
|
|
* for displaying and serializing the value. |
