Test:

add some node elements to the LinkedElements list but without taking ownership or performing any memory management. This usage pattern is helpful when the node elements are already managed elsewhere.

Note

we're still (intrusively) using the next pointer within the node elements. This means, that still a given node can't be member in multiple lists.

Test:

to support using LinkedElements within RAII-style components, all the elements might be added in one sway, by pulling them from a Lumiera Forward Iterator. In case this is done in the ctor, any exception while doing so will trigger cleanup of all elements (and then failure of the ctor altogether)

inlineprivate

Test:

use custom allocator to create list elements

• a dedicated policy allows to refer to an existing AllocationCluster and to arrange for all object destructors to be called when this cluster goes out of scope
• a C++ standard allocator can also be used; as an example, again an AllocationCluster is used, but this time with the default adapter, which places objects tight and skips invocation of destructors; however, since the LinkedElements destructor is called, it walks all elements and delegates through std::allocator_traits, which will invoke the (virtual) base class destructors.
