BlockFlow< CONF >::AllocatorHandle Class Reference

#include "vault/gear/block-flow.hpp"

Description

template<class CONF = blockFlow::DefaultConfig>
class vault::gear::BlockFlow< CONF >::AllocatorHandle

Local handle to allow allocating a collection of Activities, all sharing a common deadline.

Internally, these records are maintained in fixed-sized extents and thus allocations may overflow — leading to allocation of further extents. However, this extension is handled transparently by the embedded iterator. Moreover, a back-connection to the BlockFlow instance is maintained, enabling the latter to manage the Epoch spacing dynamically.
