23 | * Provides a framework for serialization of objects and primitives. The | ||
24 | * archive will handle any basic primitive, a few special types, like char * | ||
25 | * strings, as well as STL classes and anything that inherits from the | ||
26 | * Archival class. Each ArchiveBinary operates on a Stream, so you can send the | ||
27 | * data using an ArchiveBinary almost anywhere. | ||
28 | * | ||
29 | * In order to use an ArchiveBinary to store something to a file, try something | ||
30 | * like: | ||
31 | *@code | ||
32 | * File sOut("output", "wb"); // This is a stream subclass | ||
33 | * ArchiveBinary ar( sOut, ArchiveBinary::save ); | ||
34 | * ar << myClass; | ||
35 | @endcode | ||
36 | * In this example myClass is any class that inherits from Archival. When | ||
37 | * the storage operator is called, the Archival::archive() function in the | ||
38 | * myClass object is called with a reference to the ArchiveBinary. This can be | ||
39 | * handled in one of two ways: | ||
40 | *@code | ||
41 | * void MyClass::archive( ArchiveBinary &ar ) | ||
42 | * { | ||
43 | * ar && sName && nAge && sJob; | ||
44 | * } | ||
45 | @endcode | ||
46 | * Here we don't worry about weather we're loading or saving by using the | ||
47 | * smart && operator. This allows us to write very consistent, very simple | ||
48 | * archive functions that really do a lot of work. If we wanted to do | ||
49 | * something different in the case of loading or saving we would do: | ||
50 | *@code | ||
51 | * void MyClass::archive( ArchiveBinary &ar ) | ||
52 | * { | ||
53 | * if( ar.isLoading() ) | ||
54 | * { | ||
55 | * ar >> sName >> nAge >> sJob; | ||
56 | * } else | ||
57 | * { | ||
58 | * ar << sName << nAge << sJob; | ||
59 | * } | ||
60 | * } | ||
61 | @endcode | ||
62 | * ArchiveBinary currently does not provide facility to make fully portable | ||
63 | * archives. For example, it will not convert between endianness for you, | ||
64 | * nor will it take into account differences between primitive sizes on | ||
65 | * different platforms. This, at the moment, is up to the user to ensure. | ||
66 | * One way of dealing with the latter problem is to make sure and use | ||
67 | * explicit primitive types from the stdint.h header, i.e. int32_t. | ||
