Overloads

GetOrCreateSharedFragment(const T &)

Description

Returns or creates a shared struct associated to a given shared fragment set of values identified internally by a CRC. Use this overload when an instance of the desired shared fragment type is available and that can be used directly to compute a CRC (i.e., UE::StructUtils::GetStructInstanceCrc32) e.g., USTRUCT() struct FIntSharedFragment : public FMassSharedFragment {

int32 Value = 0; };

FIntSharedFragment Fragment; Fragment.Value = 123; const FSharedStruct SharedStruct = EntityManager.GetOrCreateSharedFragment(Fragment);

@params Fragment Instance of the desired fragment type

FSharedStruct to the matching, or newly created shared fragment

GetOrCreateSharedFragment(TArgs &&...)

Description

Returns or creates a shared struct associated to a given shared fragment set of values identified internally by a CRC. Use this overload when values can be provided as constructor arguments for the desired shared fragment type and that can be used directly to compute a CRC (i.e., UE::StructUtils::GetStructInstanceCrc32) e.g., USTRUCT() struct FIntSharedFragment : public FMassSharedFragment {

FIntSharedFragment(const int32 InValue) : Value(InValue) {}

int32 Value = 0; };

const FSharedStruct SharedStruct = EntityManager.GetOrCreateSharedFragment(123);

FSharedStruct to the matching, or newly created shared fragment

GetOrCreateSharedFragment(const UScriptStruct &, const uint8 *)

Description

Returns or creates a shared struct associated to a given shared fragment set of values identified internally by a CRC. Use this overload when the reflection data and the memory of an instance of the desired shared fragment type is available and that can be used directly to compute a CRC (i.e., UE::StructUtils::GetStructInstanceCrc32) e.g., FSharedStruct SharedStruct = EntityManager.GetOrCreateSharedFragment(*StructView.GetScriptStruct(), StructView.GetMemory());

@params InScriptStruct Reflection data structure associated to the desired fragment type @params InStructMemory Actual data of the desired fragment type

const FSharedStruct & GetOrCreateSharedFragment

    const UScriptStruct & InScriptStruct,  
    const uint8 * InStructMemory  
)

const FSharedStruct & GetOrCreateSharedFragment (     const UScriptStruct & InScriptStruct,     const uint8 * InStructMemory )

FSharedStruct to the matching, or newly created shared fragment

GetOrCreateSharedFragment(const FConstStructView, TArgs &&...)

Description

Returns or creates a shared struct associated to a given shared fragment set of values identified internally by a CRC. Use this overload when a different struct should be used to compute a CRC (i.e., UE::StructUtils::GetStructInstanceCrc32) and values can be provided as constructor arguments for the desired shared fragment type e.g.,

USTRUCT() struct FIntSharedFragmentParams {

FInSharedFragmentParams(const int32 InValue) : Value(InValue) {}

int32 Value = 0; };

USTRUCT() struct FIntSharedFragment : public FMassSharedFragment {

FIntSharedFragment(const FIntConstSharedFragmentParams& InParams) : Value(InParams.Value) {}

int32 Value = 0; };

FIntSharedFragmentParams Params(123); const FSharedStruct SharedStruct = EntityManager.GetOrCreateSharedFragment(FConstStructView::Make(Params), Params);

@params HashingHelperStruct Struct view passed to UE::StructUtils::GetStructInstanceCrc32 to compute the CRC @params InArgs List of arguments provided to the constructor of the desired fragment type
