It refines the s11n interface to almost-minimal, while still leaving the full power of the underlying framework at the clients' disposals if they need it. It also provides a binding to the default i/o implementation (the s11n::io-related Serializers), meaning that clients don't have to deal with file formats at all, and almost never even need to deal with the Serializer interface.
It is completely compatible with the core s11n framework, but directly provides only a subset of the interface: those operations common to most client-side use-cases, and those functions where s11nlite can eliminate one of the required template parameters (s11n's conventional NodeType argument, which s11nlite hard-codes in its note_type typedef).
This implementation can easily be used as a basis for writing custom client-side, s11n-based serialization frameworks.
Suggestions for including specific features into this interface are of course welcomed.
Common conventions concerning this API:
As of version 1.1, s11nlite is primarily a wrapper around the type s11nlite::client_api<>. Many of s11nlite's functions internally use a client_api instance to do their work. This allows clients to swap out most of the s11nlite implementation with their own at runtime, while still allowing all s11nlite clients to use the same front-end API.

The s11n::node_traits type for node_type.
Definition at line 88 of file s11nlite.hpp. |
|
node_type is the type used to store/load a Serializable object's data. FYI: node_type might change to s11n::s11n_node in 1.1, because that implementation is a tiny bit more lightweight than s11n::data_node, and was designed specifically with node_traits in mind (data_node came much earlier than either of them). If you only use node_traits to access nodes' data then your code will be oblivious to this change (but will need a recompile). Definition at line 85 of file s11nlite.hpp. |
|
This is the base-most type of the serializers used by s11nlite.
Definition at line 93 of file s11nlite.hpp. |
|
Returns a new instance of the given serializer class, or 0 if one could not be loaded. e.g., register_serializer() will do the trick. If no serializer for classname is found and classname does not contain the string "_serializer", then then (classname+"_serializer") is tried. This is intended to ease DLL lookups for the conventional abbreviations for the Serializer classes (i.e., my_serializer). The caller owns the returned pointer, which may be 0. Definition at line 158 of file serializers.hpp. |
|
Returns a new instance of the default serializer class. The caller owns the returned pointer. |
|
Tries to deserialize src into target. Returns true on success. If false is returned then target is not guaranteed to be in a useful state: this depends entirely on the object (but, it could be argued, it it was in a useful state its deserialize operator would have returned true!).

See s11n::deserialize(). ACHTUNG: if you are using both s11n and s11nlite namespaces this function will be ambiguous with one provided in the namespace s11n. You must then qualify it with the namespace of the one you wish to use. Definition at line 310 of file s11nlite.hpp. References instance().

A non-const overload. Ownership is not modified by calling this function: normally the parent node owns it. |
|
Sets the client_interface object used by the s11nlite API. Ownership of newinstance IS NOT transfered. Passing NULL will cause it to revert to the default instance. newinstance must live as long as any client is using s11nlite, and when newinstance is destroyed, 0 must be passed to this function to disassociate the object from the library. |

Returns the client_interface object used by the s11nlite API. There is guaranteed to return *some* object, except possibly post-main() (where all bets are off).

"Casts" t1 to t2 using serialization. This will work whenever t1 and t2 are "semantically compatible", whatever that really means. It can be used, e.g., to copy a list<int> to a vector<double>, provided both types have been proxied. In practice, this means: if Type1 and Type2 both use the same, or compatible, de/ser algorithms, they are s11n_cast-able to one another. Note that in the case of containers, the pointerness of the contained types is irrelevant: this works on both, thus a list<int> can be "cast" to a vector<double*>. As usual for a failed deserialization, if it returns false then t2 may be in an undefined state. There is no guaranty, however, that t2's deserialize operator will ever be called, as the serialization of t1 must first succeed for that to happen. Type2 may not currently be a pointer type, but Type1 may be. This will be fixed someday (when someone complains). Exceptions and errors: On error this function will return false or propagate an exception, as dictated by serialize() and then deserialize() (in that order). If Type1 and Type2 are not guaranteed to be monomorphic or base-most Serializable types, then it is good practice to explicitely specify them as templatized parameters, and not rely on implicit type selection, which might choose the wrong type (not the base-most one, which is what s11n is "keyed" to), which will mean that s11n "can't find" the registration code for the type.
