List of all members.

Detailed Description

The base class for all DataSource's The DataSource is an object containing Data of any type. It's interface is designed for dynamic build-up and destruction of these objects and allowing Commands, Properties etc to use them as 'storage' devices which have the dual copy() /clone() semantics (which is heavily used by the Orocos Task Infrastructure).

DataSource's are reference counted and must be allocated on the headp. Use DataSourceBase::shared_ptr or DataSource<T>::shared_ptr to deal with cleanup of allocated DataSources. You are not allowed to delete a DataSource. If you must have the pointer of a DataSource, use the .get() method of the shared_ptr class.

Once a newly created DataSource is assigned to a shared_ptr, it will be deleted when that pointer goes out of scope and is not shared by other shared_ptr objects.

oro_atomic_t refcount [mutable, protected]

We keep the refcount ourselves.

We aren't using boost::shared_ptr, because boost::intrusive_ptr is better, exactly because it can be used with refcounts that are stored in the class itself. Advantages are that the shared_ptr's for derived classes use the same refcount, which is of course very much desired, and that refcounting happens in an efficient way, which is also nice :)
