## Detailed Description

### template<typename T>
class ValuedUserInfo< T >

The main userinfo template class. It should be derived whenever you need a new userinfo of a class which does not contain any subelements. It is the case of basic classes(or types) like int, string, double, etc.

The only thing left is to translate its public string attribute 'value' into a value of type T and also implement conversion in the other way round. For that, an overloading of methods T* AssemblyInstance() / bool DisassemblyInstance(T &instance) is fruitful. See some valued userinfo below as an example.

## Member Function Documentation

template<class T>

static T* UserInfo::Assembly | ( | DOMElement & | element,
|  | const string | tagName |
| ) |  |  | `[inline, static, inherited]`

This methods tries to assembly a new instance of type T (or some of its descendant types) according to a data stored in a DOMNode named tagName within a child nodes of the passed element. If an error occurs, it returns a NULL pointer.

References Attribute::Get(), and Attribute::type.

template<class T>

static bool UserInfo::Disassembly | ( | T & | instance,
|  | DOMElement & | element,
|  | const string | tagName,
|  | const string | help |
| ) |  |  | `[inline, static, inherited]`

This methods tries to disassembly an instance of type T (or some of its descendant types) and build DOM tree accordingly. Then, it creates a new DOMNode named according tagName and connecti it to the passed DOMElement as a new child node (with a help attribute filled).

References Attribute::help, Attribute::Set(), and Attribute::type.

template<class T>

static bool UserInfo::Disassembly | ( | T & | instance,
|  | DOMElement & | element,
|  | const string | tagName |
| ) |  |  | `[inline, static, inherited]`

This methods tries to disassembly an instance of type T (or some of its descendant types) and build DOM tree accordingly. Then, it creates a new DOMNode named according tagName and connecti it to the passed DOMElement as a new child node.

References UserInfo::Disassembly().

## Member Data Documentation

template<typename T>

const TypedUserInfo<T>& TypedUserInfo< T >::instance`[static, protected, inherited]`

the only instance of this class (each type T has its own instance) which is used as a factory for processing related userinfos
