	Compile the query terms into a form we can easily process.

void	match (const EntityToArchetypeMap &entityToArchetypeMap, const ArchetypeDArray &allArchetypes, ArchetypeId archetypeLastId)
	Tries to match the query against archetypes in entityToArchetypeMap. This is necessary so we do not iterate all chunks over and over again when running queries.

void	calculate_sort_data ()
	Calculates the sort data for the archetypes in the cache. This allows us to iterate entites in the order they are sorted across all archetypes.

Member Function Documentation

◆ match()

void gaia::ecs::QueryInfo::match	(	const EntityToArchetypeMap &	entityToArchetypeMap,
		const ArchetypeDArray &	allArchetypes,
		ArchetypeId	archetypeLastId
	)

inline

Tries to match the query against archetypes in entityToArchetypeMap. This is necessary so we do not iterate all chunks over and over again when running queries.

Parameters

entityToArchetypeMap	Map of all archetypes
allArchetypes	List of all archetypes
archetypeLastId	Last recorded archetype id

Warning: Not thread safe. No two threads can call this at the same time.

◆ remove()

void gaia::ecs::QueryInfo::remove ( Archetype * pArchetype )

inline

Removes an archetype from cache.

Parameters

pArchetype Archetype to remove
