Member Typedef Documentation

◆ AdditionalDataCallback

using FLinkerSave::AdditionalDataCallback = TUniqueFunction<void(FLinkerSave& ExportsArchive, FArchive& DataArchive, int64 DataStartOffset)>

Callback for arbitrary serializers to append data to the end of the ExportsArchive. Some PackageWriters used by SavePackage will write this data to a separate archive.

Parameters

ExportsArchive	The archive containing the UObjects and structs, this is always this LinkerSave.
DataArchive	The archive to which the data should be written. Might be this LinkerSave, or might be a separate archive.
DataStartOffset	The offset to the beginning of the range in DataArchive that should be stored in the UObject or struct's export data. Reading at DataStartOffset from the FArchive passed into Serialize during a load will return the data that the callback wrote to DataArchive.

FLinkerSave::FLinkerSave	(	UPackage *	InParent,
		FArchive *	InSaver,
		bool	bForceByteSwapping,
		bool	bInSaveUnversioned = `false`
	)

Constructor for custom savers. The linker assumes ownership of the custom saver.

◆ FLinkerSave() [4/4]

PRAGMA_ENABLE_DEPRECATION_WARNINGS FLinkerSave::FLinkerSave ( UPackage * InParent )

explicit

Partially construct the FLinkerSave. No FArchive functions may be called on *this until AssignSaver has been called with a non-null FArchive.

Member Function Documentation

◆ AssignMemorySaver()

void FLinkerSave::AssignMemorySaver	(	bool	bForceByteSwapping,
		bool	bInSaveUnversioned = `false`
	)

Construct a FMemoryWriter archive and call AssignSaver with it.

See also: AssignSaver.

◆ AssignSaveContext()

void FLinkerSave::AssignSaveContext ( FSaveContext * InContext )

inline

Assign the temporary save context with the linker

◆ AssignSaver()

void FLinkerSave::AssignSaver	(	FArchive *	InSaver,
		bool	bForceByteSwapping,
		bool	bInSaveUnversioned = `false`
	)

Assign the Saver that will receive the binary data for the package and write it to disk/memory/unspecified. Must be called only once, after construction and before any calls to FArchive functions on this. Takes ownership of the given archive, and deletes it in CloseAndDestroySaver or destructor.

Parameters

bForceByteSwapping	Passed to FArchive::IsByteSwapping
bInSaveUnversioned	Passed to FPackageFileSummary::bUnversioned, which if true removes native versioning and custom versions from the saved package. Used for cooked packages, which exactly match native runtime version.

◆ AssignSaverInternal()

void FLinkerSave::AssignSaverInternal	(	FArchive *	InSaver,
		bool	bForceByteSwapping,
		bool	bInSaveUnversioned
	)

protected

◆ CloseAndDestroySaver()

bool FLinkerSave::CloseAndDestroySaver ( )

Closes and deletes the Saver (file, memory or custom writer) which will close any associated file handle. Returns false if the owned saver contains errors after closing it, true otherwise.

◆ ForEachBulkDataCookedIndex()

		EBulkDataPayloadType	Type
	)		const

◆ GetArchiveName()

This is overridden for the specific Archive Types

Reimplemented from FArchive.

const FString & FLinkerSave::GetFilename ( ) const

Get the filename being saved to

◆ GetLinker()

virtual FLinker * FLinkerSave::GetLinker ( )

Member Data Documentation

◆ AdditionalDataToAppend

TArray<AdditionalDataCallback> FLinkerSave::AdditionalDataToAppend

Array of callbacks that will be invoked when it is possible to serialize out data to the end of the output file.

◆ bIsWritingHeaderSoftObjectPaths

bool FLinkerSave::bIsWritingHeaderSoftObjectPaths = false

Flag that indicate if we are currently serializing the package header soft object paths. Used to disable mapping while serializing the header itself.

◆ bProceduralSave

bool FLinkerSave::bProceduralSave = false

Set to true when the package is being saved due to a procedural save. Any save without the the possibility of user-generated edits to the package is a procedural save (Cooking, EditorDomain). This allows us to execute transforms that only need to be executed in response to new user data.

◆ bRehydratePayloads

bool FLinkerSave::bRehydratePayloads = false

When set to true, payloads that are currently virtualized should be downloaded and stored locally with the package

◆ bUpdatingLoadedPath

bool FLinkerSave::bUpdatingLoadedPath = false

Set to true when the LoadedPath of the package being saved is being updated. This allows us to update the in-memory package when it is saved in editor to match its new save file. This is used e.g. to decide whether to update the in-memory file offsets for BulkData.

◆ CellIndicesMap

TMap<Verse::VCell*, FPackageIndex> FLinkerSave::CellIndicesMap

◆ CurrentlySavingExport

FPackageIndex FLinkerSave::CurrentlySavingExport

◆ PackagesToScriptSHAMap

PRAGMA_DISABLE_DEPRECATION_WARNINGS TMap< FString, TArray< uint8 > > FLinkerSave::PackagesToScriptSHAMap

static

A mapping of package name to generated script SHA keys

◆ PackageTrailerBuilder

TUniquePtr<UE::FPackageTrailerBuilder> FLinkerSave::PackageTrailerBuilder

◆ PostSaveCallbacks

TArray<TUniqueFunction<void(const FPackagePath& PackagePath, FObjectPostSaveContext ObjectSaveContext)> > FLinkerSave::PostSaveCallbacks

Array of callbacks that will be invoked when the package has successfully saved to disk. The callbacks will not be invoked if the package fails to save for some reason. Unlike subscribing to the UPackage::PackageSavedEvent this callback allows custom data via lambda capture.

Parameters

PackagePath The path of the package

◆ Saver

FArchive* FLinkerSave::Saver = nullptr

The archive that actually writes the data to disk.

◆ SearchableNamesObjectMap

TMap<const UObject *, TArray<FName> > FLinkerSave::SearchableNamesObjectMap

List of Searchable Names, by object containing them. This gets turned into package indices later

◆ SidecarDataToAppend

TArray<FSidecarStorageInfo> FLinkerSave::SidecarDataToAppend

Used by FEditorBulkData to add payloads to be added to the payload sidecar file (currently an experimental feature)

◆ SoftObjectPathIndices
