Detailed Description

Helper class to remap package imports during loading. This is usually when objects in a package are outer-ed to object in another package or vice versa. Instancing such a package without a instance remapping would resolve imports to the original package which is not desirable in an instancing context (i.e. loading a level instance) This is because an instanced package has a different name than the package file name on disk, this class is used in the linker to remaps reference to the package name as stored in import tables on disk to the corresponding instanced package or packages we are loading.

Member Function Documentation

AddPackageMapping()

void FLinkerInstancingContext::AddPackageMapping	(	FName	Original,
		FName	Instanced
	)

Add a mapping from a package name to a new package name. There should be no separators (. or :) in these strings.

AddPackageMappingFunc()

void FLinkerInstancingContext::AddPackageMappingFunc

(

TFunction< FName(FName)>

InInstancedPackageMapFunc

)

Add a mapping function from a package name to a new package name. This function should be thread-safe, as it can be invoked from ALT.

AddPathMapping()

void FLinkerInstancingContext::AddPathMapping	(	FSoftObjectPath	Original,
		FSoftObjectPath	Instanced
	)

Add a mapping from a top level asset path (/Path/To/Package.AssetName) to another.

AddTag()

void FLinkerInstancingContext::AddTag

(

FName

NewTag

)

AppendTags()

void FLinkerInstancingContext::AppendTags

(

const TSet< FName > &

NewTags

)

DuplicateContext()

FLinkerInstancingContext FLinkerInstancingContext::DuplicateContext ( const FLinkerInstancingContext &  InLinkerInstancingContext )

FSoftObjectPath &

InOutSoftObjectPath

)

const

GetInstancedPackageName() [1/2]

static FString FLinkerInstancingContext::GetInstancedPackageName ( const FString &  InOuterPackageName, const FString &  InPackageName  )

inlinestatic

Return the instanced package name for a given instanced outer package and an object package name

GetInstancedPackageName() [2/2]

static FName FLinkerInstancingContext::GetInstancedPackageName ( FName  InOuterPackageName, FName  InPackageName  )

inlinestatic

const

RemapPackage()

FName FLinkerInstancingContext::RemapPackage

(

const FName &

PackageName

)

const

Remap the package name from the import table to its instanced counterpart, otherwise return the name unmodified.

RemapPath()

FSoftObjectPath FLinkerInstancingContext::RemapPath

(

const FSoftObjectPath &

Path

)

const

Remap the top level asset part of the path name to its instanced counterpart, otherwise return the name unmodified. i.e. remaps /Path/To/Package.AssetName:Inner to /NewPath/To/NewPackage.NewAssetName:Inner
