## Detailed Description

### template<class T>
class QuantLib::Composite< T >

Composite pattern.

The typical use of this class is:

            class CompositeFoo : public Composite<Foo> {
                ...
            };

which causes CompositeFoo to inherit from Foo and provides it with methods for adding components. Of course, any abstract Foo interface must still be implemented.
