Detailed Description

FStreamSizeHolder Declaration remembers size of stream chunk for backward compatibility.

Example:

externalize (a)
{
    FStreamSizeHolder sizeHolder;
    sizeHolder.beginWrite ();       // sets start mark, writes dummy size
    a << ....
    sizeHolder.endWrite ();         // jumps to start mark, updates size, jumps back here
}
 
internalize (a)
{
    FStreamSizeHolder sizeHolder;
    sizeHolder.beginRead ();        // reads size, mark
    a >> ....
    sizeHolder.endRead ();          // jumps forward if new version has larger size
}
