Detailed Description

template<class _Derived, class _NumericIdType>
struct zypp::base::ProvideNumericId< _Derived, _NumericIdType >

Base class for objects providing a numeric Id.

The ctor creates a NumericId from some static counter.

The only assertion is that 0 is not used as an Id, unless the derived class explicitly requests this by using ProvideNumericId( const void *const ).

Why should you want to use 0 as an Id? E.g if your class provides some (singleton) No-object. Might be desirable to make the No-object have No-Id.

* struct Foo : public base::ProvideNumericId<Foo,unsigned>
* {};
* Foo foo;
* foo.numericId(); // returns foo's NumericId.
