BloombergLP::bsltf::StdAllocatorAdaptor::select_on_container_copy_construction

Return an allocator adaptor for the allocator object returned by the select_on_container_copy_construction class method in the allocator_traits class template for the allocator object, of the (template parameter) type ALLOCATOR, associated with this adaptor. The allocator_traits class template presumably delegates this call to the allocator object if such an operation is supported by the ALLOCATOR type, or provides a suitable default behavior if such an operation is not supported.
