|
* We should have thought of storing those in the data...
|
|
* It is possible to extend the data structure by putting additional values
|
|
* in places that are inaccessible by ordinary enumeration of the item tree.
|
|
* For example, additional integers could be stored at the beginning or
|
|
* end of the key strings; this could be indicated by a minor version number,
|
|
* and the data swapping would have to know about these values.
|
|
*
|
|
* The data structure does not forbid keys to be shared, so we must swap
|
|
* all keys once instead of each key when it is referenced.
|
|
*
|
|
* These swapping functions assume that a resource bundle always has a length
|
|
* that is a multiple of 4 bytes.
|
|
* Currently, this is trivially true because genrb writes bundle tree leaves
|
|
* physically first, before their branches, so that the root table with its
|
|
* array of resource items (uint32_t values) is always last.
