Function Documentation

AddDependency()

template<uint32 FlagWidth>

void AddDependency	(	FDependsNode *	InDependency,
		UE::AssetRegistry::EDependencyProperty	AddProperties,
		UE::AssetRegistry::EDependencyProperty	CategoryMask,
		TArray< FDependsNode * > &	Dependencies,
		TBitArray<> *	FlagBits,
		uint8(*)(UE::AssetRegistry::EDependencyProperty)	PropertiesToByte,
		bool	IsSorted
	)

EnumerateMatchingDependencyFlags()

template<uint32 FlagWidth, typename VisitorType >

void EnumerateMatchingDependencyFlags	(	const TBitArray<> *	FlagBits,
		UE::AssetRegistry::EDependencyProperty	CategoryMask,
		UE::AssetRegistry::EDependencyProperty(*)(uint8)	ByteToProperties,
		int32	ListIndex,
		const UE::AssetRegistry::FDependencyQuery &	SearchFlags,
		VisitorType &&	Visitor
	)

Helper function for IterateDependencyList, which itself is a helper function for FDependsNode functions. This function is given an index into one of the lists. All of the data for the list and how to interpret it is also passed in. The function looks of the set of DependencyProperty flag groups for the index, and iterates over that set, and calls the callback on each flag group that matches the requested SearchFlags.

IterateDependencyList() [1/2]

template<uint32 FlagWidth, typename CallbackType >

void IterateDependencyList	(	CallbackType &&	InCallback,
		const FDependsNode *	SearchNode,
		UE::AssetRegistry::EDependencyCategory	SearchCategory,
		const UE::AssetRegistry::FDependencyQuery &	SearchFlags,
		UE::AssetRegistry::EDependencyCategory	ListCategory,
		UE::AssetRegistry::EDependencyProperty	CategoryMask,
		const TArray< FDependsNode * > &	Dependencies,
		const TBitArray<> *	FlagBits,
		UE::AssetRegistry::EDependencyProperty(*)(uint8)	ByteToProperties,
		bool	IsSorted
	)

Helper function for IterateOverDependencies, ContainsDependency, and others that need to find a given dependency in one of an FDependsNode's list of dependencies, while filtering by the list of DependencyProperties associated with each dependency. This function is given all of the data for the list and how to interpret it, and a requested SearchNode and SearchFlags. The function looks up the SearchNode in the list of dependencies, and iterates over the set of DependencyProperty flag groups for each dependency, and calls the callback with each flag group on the dependency that matches the requested SearchFlags.

IterateDependencyList() [2/2]

template<uint32 FlagWidth, typename CallbackType >

void IterateDependencyList	(	CallbackType &&	InCallback,
		UE::AssetRegistry::EDependencyCategory	SearchCategory,
		const UE::AssetRegistry::FDependencyQuery &	SearchFlags,
		UE::AssetRegistry::EDependencyCategory	ListCategory,
		UE::AssetRegistry::EDependencyProperty	CategoryMask,
		const TArray< FDependsNode * > &	Dependencies,
		const TBitArray<> *	FlagBits,
		UE::AssetRegistry::EDependencyProperty(*)(uint8)	ByteToProperties,
		bool	IsSorted
	)

Helper function for GetDependencies, IterateOverDependencies, and others that need to find dependencies in each of an FDependsNode's list of dependencies, while filtering by the list of DependencyProperties associated with each dependency. This function is given all of the data for the list and how to interpret it, and a requested SearchFlags. The function iterates over all dependencies in the list, and iterates over the set of DependencyProperty flag groups for each dependency, and calls the callback with the dependency and with each flag group on the dependency that matches the requested SearchFlags.

RemoveAll()

template<uint32 FlagWidth>

void RemoveAll	(	const TUniqueFunction< bool(const FDependsNode *)> &	ShouldRemove,
		TArray< FDependsNode * > &	Dependencies,
		TBitArray<> *	FlagBits,
		bool	IsSorted,
		EAllowShrinking	ShrinkPolicy
	)

RemoveDependency()

template<uint32 FlagWidth>

void RemoveDependency	(	FDependsNode *	InDependency,
		TArray< FDependsNode * > &	Dependencies,
		TBitArray<> *	FlagBits,
		bool	IsSorted,
		bool	bAllowShrinking
	)

SortDependencyList()

template<uint32 FlagWidth>

void SortDependencyList	(	TArray< FDependsNode * > &	Dependencies,
		TBitArray<> *	Flags,
		EAllowShrinking	ShrinkPolicy
	)
