Syntax

class FArchiveProxy : public FArchive

Remarks

Base class for archive proxies.

Archive proxies are archive types that modify the behavior of another archive type.

Variables

  Type Name Description
Protected variable FArchive & InnerArchive Holds the archive that this archive is a proxy to.

Constructors

  Type Name Description
Public function  

FArchiveProxy ( FArchive& InInnerArchive
)

 Creates and initializes a new instance of the archive proxy.
Public function   Non-copyable.
Public function    

Destructors

  Type Name Description
Public function    

Overridden from FArchive

  Type Name Description
Public function Virtual void

AttachBulkData ( UObject* Owner,
FBulkData* BulkData
)

 Attaches/ associates the passed in bulk data object with the linker.
Public function Virtual bool

AttachExternalReadDependency ( FExternalReadCallback& ReadCallback
)

 Adds external read dependency
Public function Virtual bool

Close ()

 Attempts to close and finalize any handles used for backing data storage, returns true if it succeeded.
Public function Virtual void

DetachBulkData ( FBulkData* BulkData,
bool bEnsureBulkDataIsLoaded
)

 Detaches the passed in bulk data object from the linker.
Public function Virtual void

Flush ()

 Attempts to finish writing any buffered data to disk/permanent storage.
Public function Virtual void Flushes cache and frees internal data.
Public function Virtual void Inform the archive that a blueprint would like to force finalization, normally this is triggered by CDO load, but if there's no CDO we force finalization.
Public function Virtual FArchive * Returns a pointer to an archive that represents the same data that the current archive covers, but that can be cached and reused later In the case of standard archives, this function will just return a pointer to itself.
Public function Virtual Const bool

IsProxyOf ( FArchive* InOther
)

 Determine if the given archive is a valid "child" of this archive.
Public function Virtual void Called when an object stops serializing property data using script serialization.
Public function Virtual void Called when an object begins serializing property data using script serialization.
Public function Virtual Const void

MarkSearchableName ( const TObjectPtr< const UObject >& TypeObject,
const FName& ValueName
)

 Called to register a reference to a specific name value, of type TypeObject (UEnum or UStruct normally).
Public function Virtual void  
Public function Virtual void

PopSerializedProperty ( FProperty* InProperty,
const bool bIsEditorOnlyProperty
)

 Pops editor-only marker from the stack of currently serialized properties
Public function Virtual bool

Precache ( int64 PrecacheOffset,
int64 PrecacheSize
)

 Hint the archive that the region starting at passed in offset and spanning the passed in size is going to be read soon and should be precached.
Public function Virtual void

Preload ( UObject* Object
)

 Tells the archive to attempt to preload the specified object so data can be loaded out of it.
Public function Virtual void

PushDebugDataString ( const FName& DebugData
)

 Debug stack storage if you want to add data to the archive for usage further down the serialization stack this should be used in conjunction with the FScopeAddDebugData struct
Public function Virtual void

PushSerializedProperty ( FProperty* InProperty,
const bool bIsEditorOnlyProperty
)

 Pushes editor-only marker to the stack of currently serialized properties
Public function Virtual void

Seek ( int64 InPos
)

 Attempts to set the current offset into backing data storage, this will do nothing if there is no storage.
Public function Virtual void

Serialize ( void* V,
int64 Length
)

  
Public function Virtual void

SerializeBits ( void* Bits,
int64 LengthBits
)

  
Public function Virtual bool Serialize bulk data.
Public function Virtual void

SerializeInt ( uint32& Value,
uint32 Max
)

  
Public function Virtual void

SerializeIntPacked ( uint32& Value
)

 Packs int value into bytes of 7 bits with 8th bit for 'more'
Public function Virtual bool

SetCompressionMap ( TArray< FCompressedChunk >* CompressedChunks,
ECompressionFlags CompressionFlags
)

 Sets mapping from offsets/ sizes that are going to be used for seeking and serialization to what is actually stored on disk.

Overridden from FArchiveState

  Type Name Description
Public function Virtual bool

AtEnd ()

 Returns true if the current location within the backing data storage is at the end, always returns false if there is no storage.
Public function Virtual void

CountBytes ( SIZE_T InNum,
SIZE_T InMax
)

 Called to get the computed size from a size-detecting archive after it has finished serializing.
Public function Virtual UObject * Called to retrieve the archetype from the event driven loader.
Public function Virtual Const FString Returns the name of the Archive.
Public function Virtual Const const FCustomVersionContainer & Gets the custom version numbers for this archive.
Public function Virtual ::FArchiveState & Returns lowest level archive state, proxy archives will override this.
Public function Virtual FLinker * If this archive is a FLinkerLoad or FLinkerSave, returns a pointer to the ULinker portion.
Public function Virtual Const FString Get the localization namespace that this archive should use when serializing text properties.
Public function Virtual Const bool Returns true if the stack of currently serialized properties contains an editor-only property
Public function Virtual void Resets the custom version numbers for this archive.
Public function Virtual void

SetCustomVersions ( const FCustomVersionContainer& CustomVersionContainer
)

 Sets the custom version numbers for this archive.
Public function Virtual void

SetFilterEditorOnly ( bool InFilterEditorOnly
)

 Sets a flag indicating that this archive needs to filter editor-only content.
Public function Virtual void

SetLocalizationNamespace ( const FString& InLocalizationNamespace
)

 Set the localization namespace that this archive should use when serializing text properties.
Public function Virtual void Overrides the property that is currently being serialized
Public function Virtual void

SetSerializedPropertyChain ( const FArchiveSerializedPropertyChain* InSerializedPropertyChain,
FProperty* InSerializedPropertyOverride
)

 Set the raw serialized property chain for this archive, optionally overriding the serialized property too (or null to use the head of the property chain)
Public function Virtual Const bool

ShouldSkipProperty ( const FProperty* InProperty
)

 Checks whether the archive wants to skip the property independent of the other flags
Public function Virtual int64

Tell ()

 Returns the current location within the backing data storage, which can possibly be passed to Seek later to restore a read/write location.
Public function Virtual int64 Returns total size of the backing data storage.
Public function Virtual Const bool Checks whether the archive is used to resolve out-of-date enum indexes If function returns true, the archive should be called only for objects containing user defined enum
