Epoch< ALO >::EpochGate Struct Reference

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

Description

template<class ALO>
struct vault::gear::blockFlow::Epoch< ALO >::EpochGate

specifically rigged GATE Activity, used for managing Epoch metadata

• the Condition::rest tracks pending async IO operations
• the Condition::deadline is the nominal deadline of this Epoch
• the field next points to the next free allocation Slot to use

	Core Operation: Activate and perform this Activity.
template<class EXE >
activity::Proc	dispatch (Time now, EXE &executionCtx)
	Entrance point for an activation, which has been dispatched indirectly through the dispatch and/or priority queue; typically this is achieved by invoking the post-λ on the executionCtx, or by activating a POST-Activity.

Constructor & Destructor Documentation

EpochGate()

template<class ALO >

EpochGate ( )

inline

Note

initially by default there is...

• effectively no deadline
• no IO operations pending (i.e. we can just discard the Epoch)
• the next usable Slot is the last Storage slot, and will be decremented until there is only one slot left (EpochGate itself)

Warning

EpochGate is assumed to sit in the Epoch's first slot
