Detailed Description

template<typename Selects, typename Missings, typename Conditions, bool AutoLock, typename... Cs>
class ecstasy::Registry::RegistryStackQueryMemory< Selects, Missings, Conditions, AutoLock, Cs >

Base class of RegistryStackQuery.

This class is used to allocate the queryables on the stack. At compile time it will evaluate the required queryables and reserve memory for the one requiring an allocation. It allows faster runtime because there is no dynamic allocation but longer compile time.

Note: Thanks to no_unique_address attribute, the memory reserved for the allocator is not reserved if no allocator is required, meaning there is no memory overhead.; Yes this is black magic and I'm proud of it (my brain hurts).

Template Parameters

Selects	Selected queryables in a util::meta::Traits.
Missings	Selected queryables not given in the where clause (in Cs... ) in a util::meta::Traits.
Conditions	Query runtime conditions in a util::meta::Traits.
AutoLock	Whether or not the Lockable queryables must be locked.
Cs	Selected components already present in the where clause. (Missings + Cs are all the components queried).
