Description

Public class

FArchiveCountMem

Archive for counting memory usage.

Public struct

FArchiveDiffInfo

Public class

FArchiveDiffMap

Public struct

FArchiveDiffStats

Structure that holds stats from comparing two packages

Public class

FArchiveFindCulprit

Archive for finding who references an object.

Public class

FArchiveHasReferences

Public class

FArchiveObjectCrc32

Calculates a checksum on an object's serialized data stream.

Public class

FArchiveObjectGraph

This is from FArchiveTraceRoute -This only creates object graph of all objects This can be used by other classes such as FTraceReferences - trace references of one object

Public class

FArchiveObjectPropertyMapper

Class for collecting references to objects, along with the properties that references that object.

Public class

FArchiveReferenceMarker

This archive marks all objects referenced by the specified "root set" of objects.

Public class

FArchiveReplaceObjectRef

Archive for replacing a reference to an object.

Public class

FArchiveReplaceObjectRefBase

Base class for object replacement archives

Public class

FArchiveReplaceOrClearExternalReferences

Identical to FArchiveReplaceObjectRef, but for references to private objects in other packages we clear the reference instead of preserving it (unless it makes it into the replacement map)

Public class

FArchiveScriptReferenceCollector

Public class

FArchiveShowReferences

Archive for displaying all objects referenced by a particular object.

Public class

FArchiveStackTrace

Archive that stores a callstack for each of the Serialize calls and has the ability to compare itself to an existing package on disk and dump all the differences to log.

Public class

FArchiveStackTraceIgnoreScope

Public class

FArchiveStackTraceReader

Public class

FArchiveTraceRoute

DEPRECATED: This class is out of date and misses many GC references, replace with FReferenceChainSearch.

Public class

FArchiveUObject

Base FArchive for serializing UObjects.

Public class

FArchiveUObjectFromStructuredArchive

Public class

FArchiveUObjectFromStructuredArchiveImpl

Public struct

FAsyncLoadingThreadSettings

Structure that holds the async loading thread ini settings

Public struct

FAutoRegisterLocalizationDataGatheringCallback

Struct to automatically register a callback when it's constructed

Public struct

FAutoRegisterTextReferenceCollectorCallback

Struct to automatically register a callback when it's constructed

Public class

FBulkDataAllocation

This is a wrapper for the BulkData memory allocation so we can use a single pointer to either reference a straight memory allocation or in the case that the BulkData object represents a memory mapped file region, a FOwnedBulkDataPtr.

Public class

FDeferredMessageLog

Thread safe proxy for the FMessageLog while performing async loading.

Public class

FDuplicateDataReader

Reads duplicated objects from a memory buffer, replacing object references to duplicated objects.

Public class

FDuplicateDataWriter
