declare_fields()

void MayaFlux::Buffers::PopulationConfig::declare_fields

(

const std::shared_ptr< NetworkGeometryBuffer > &

buffer

)

const

Declare the two state fields population dynamics needs.

Parameters

buffer

Buffer to declare on. Already-present names are left untouched, matching every other declare_fields in this family.

Declares mutation_alive at hash.particle_count elements (the total seed + reserve capacity) and mutation_spawn_cursor as a single element. Neither is reset by any per-cycle stage: PopulationInitProcessor writes both exactly once, and every cycle after that only ClaimAccumulateProcessor (destroy) and PopulationSpawnProcessor (spawn) ever touch them again, forward-only, until the next reseed.
