Detailed Description

Derived Data Reference

Provides a consistent way to reference derived data:

• That has the same API for the editor as for builds with cooked packages.
• That has the same API to load from the cache as from a raw buffer, a compressed buffer, or a cooked package.
• That supports asynchronous, event-driven, prioritized loading of derived data.
• That supports saving to a cooked package without loading from the cache, when using Zen.
• That replaces serialized bulk data, such as FByteBulkData, in a cooked package.

Constructor & Destructor Documentation

FDerivedData() [1/2]

UE::FDerivedData::FDerivedData ( )

default

Constructs a null reference.

FDerivedData() [2/2]

UE::FDerivedData::FDerivedData ( const DerivedData::Private::FCookedData &  CookedData )

inlineexplicit

Constructs a reference from the private representation of a cooked reference.

Member Function Documentation

GetFlags()

EDerivedDataFlags UE::FDerivedData::GetFlags ( ) const

inline

Returns the flags, which are mainly relevant for staged references.

HasData()

bool UE::FDerivedData::HasData ( ) const

inline

Returns true if this is a non-null reference.

IsCooked()

bool UE::FDerivedData::IsCooked ( ) const

inline

Returns true if this is a cooked reference.

IsNull()

bool UE::FDerivedData::IsNull ( ) const

inline

Returns true if this is a null reference.

operator bool()

UE::FDerivedData::operator bool ( ) const

inlineexplicit

Returns true if this is a non-null reference.

ReferenceEquals()

bool UE::FDerivedData::ReferenceEquals

(

const FDerivedData &

Other

)

const

Returns true if this and the other are equivalent references.

ReferenceHash()

uint32 UE::FDerivedData::ReferenceHash

(

)

const

Returns a hash that factors in the same members as ReferenceEquals.

Reset()

void UE::FDerivedData::Reset ( )

inline

Resets the reference to null.

Serialize()

void UE::FDerivedData::Serialize	(	FArchive &	Ar,
		UObject *	Owner
	)

Serializes this reference to or from a cooked package.

Friends And Related Symbol Documentation

operator<<

UE_API friend FStringBuilderBase & operator<< ( FStringBuilderBase &  Builder, const FDerivedData &  DerivedData  )

friend

Appends the name and description of this reference to the builder.

Member Data Documentation

Null

const FDerivedData UE::FDerivedData::Null

inlinestatic

A null reference.
