-
-This wxPrefConfig class is a wxConfig wrapper around PalmOS Preferences
-functionality. Preferences allow to write any structure into its database so
-wxPrefConfig writes there all entries of single group into one Preference.
-To optimize read/write operations value of preference is cached. Cache is filled
-after each change of the path (including using path to group names in all
-operations) and it is flushed on destructor, any path change on or purpose
-with Flush().
-
-Meaning of styles:
-
- wxCONFIG_USE_LOCAL_FILE => store config in "saved" preferences database
- (not to be backed up during a HotSync operation)
- wxCONFIG_USE_GLOBAL_FILE => store config in "unsaved" preferences database
- (backed up during a HotSync operation)
-
-
-Each Preference is an array of chars. First unsigned char describes
-number N of chars used for Preference size. Next N chars (string) contains
-length of rest of Preference. Preference consists in serie of entries which
-should be read in loop until in reaches end of Preference.
-
- Each entry is an set of chars with following structure:
- 1. name (null terminated)
- 2. type (single char): b,s,g,l,d (see value)
- 3. value
- - for type="b" (bool) it os "0" or "1"
- - for type="s" (string) it is null terminated set of chars
- - for type="g" (subgroup) as for "s" but string is converted to
- uint16_t for id parameter of ::PrefGetAppPreferences()
- - for type="l" (long) as for "s" but string is converted to long
- - for type="d" (double) as for "s" but string is converted to double
- - otherwise it is ""
-
-So all together first Read in group needs 3 reading from Preference:
- 1. take the length N of length
- 2. take the length M of the group content
- 3. take the group content
-and all it is in single Preference to not overload Preferences database.
-As long as each next Read/Write is performed in the same group then none
-access to Preferences is performed. Flushing needs only single writing to
-databease because all 3 parts of Preference can be prepared in memory.
-
-NOTE: wxPrefConfig can read/write only its own entries. It is impossible to
-know structures of Preferences of other non wxW applications.
