Detailed Description

template<class T, class M>
class elm::io::Printable< T, M >

This class is used to make easier the display of values controlled by a manager. This concerns values that are not self-contained to be displayed (usually because of memory place issues). The print() function is delegated to a manager object that needs to be referenced in the display of the value. This class embeds together the value and the manager to involve them in operator << display. The best usage of this class is the function elm::io::p() that avoids to manage all the type stuff as below:

class Value {
    ...
};
 
class Manager {
    ...
    void print(const Value& val, io::Output& out);
    ...
};
...
Manager m;
Value v;
cout << io::p(v, m) << io::endl;

Notice that the manager class has to provide a print() function taking the value as first parameter and the output stream as second parameter.

Parameters

T	Type of values.
M	Type of manager.
