Detailed Description

template<typename T, typename TUStructType = UScriptStruct>
struct UE::Mass::Private::TBitTypeRegistry< T, TUStructType >

Template class for registering and managing bitsets for Mass types (e.g., Fragments and Tags). Provides functionality to create builders for constructing bitsets. The type hosts a FStructTracker instance that stores information on all the types used to build bitsets via it, and only those types - as opposed to TStructTypeBitSet, which is using the same FStructTracker throughout the engine's instance lifetime.

Parameters

T	the base Mass type (e.g., FMassFragment or FMassTag).
TUStructType	the Unreal Engine struct type, default is UScriptStruct.

Member Typedef Documentation

FBitSet

template<typename T , typename TUStructType = UScriptStruct>

using UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::FBitSet = typename FBitSetBuilder::FConstBitSet

The type representing the runtime-used bitset. Const by design.

FBitSetBuilder

template<typename T , typename TUStructType = UScriptStruct>

using UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::FBitSetBuilder = TTypeBitSetBuilder<T, TUStructType, TTypeBitSetTraits<T>::RequiresBaseType>

Alias for the bitset builder specific to the type T

Constructor & Destructor Documentation

TBitTypeRegistry()

MASSENTITY_API UE::Mass::FTagBitRegistry::TBitTypeRegistry ( )

inline

Constructor that initializes the struct tracker. Uses a lambda to retrieve the UStruct representing the base type T.

Explicit template instantiation declarations for the registries

Member Function Documentation

MakeBuilder() [1/2]

template<typename T , typename TUStructType = UScriptStruct>

FBitSetFactory UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::MakeBuilder ( ) const

inline

Creates a factory for building new bitsets, essentially a FBitSetBuilder-BitSet combo.

Returns

A new FBitSetFactory instance.

MakeBuilder() [2/2]

template<typename T , typename TUStructType = UScriptStruct>

FBitSetBuilder UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::MakeBuilder ( FBitSet &  BitSet ) const

inline

Creates a bitset builder for an existing bitset.

Parameters

BitSet

the bitset instance to modify

Returns

A new FBitSetBuilder instance

RegisterType() [1/2]

template<typename T , typename TUStructType = UScriptStruct>

template<typename TType >

int32 UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::RegisterType ( )

inline

Template method to register a type with the struct tracker.

Parameters

TType

the type to register.

Returns

The index assigned to the registered type.

RegisterType() [2/2]

template<typename T , typename TUStructType = UScriptStruct>

int32 UE::Mass::Private::TBitTypeRegistry< T, TUStructType >::RegisterType ( const UScriptStruct *  Type )

inline

Registers a type with the struct tracker.

Parameters

Type	the UScriptStruct representing the type to register.

Returns

The index assigned to the registered type.
