Detailed Description
Base class for NUMAReplicator.
This class is not intended to be used directly, but only as an implementation details for collecting the non-templated parts of NUMAReplicator. It contains the replication logic, but stores all data in a type-erased manner. To actually access the data the NUMAReplicator has to be used. A derived class needs to implement a get_clone() function which creates a copy of the data to be replicated. This function will be called in a context in which the allocation policy has been set to allocate on a specific NUMA node, and need not concern itself with these details.
