Values

Name

Description

STRUCT_NoFlags

State flags.

STRUCT_Native

STRUCT_IdenticalNative

If set, this struct will be compared using native code

STRUCT_HasInstancedReference

STRUCT_NoExport

STRUCT_Atomic

Indicates that this struct should always be serialized as a single unit

STRUCT_Immutable

Indicates that this struct uses binary serialization; it is unsafe to add/remove members from this struct without incrementing the package version

STRUCT_AddStructReferencedObjects

If set, native code needs to be run to find referenced objects

STRUCT_RequiredAPI

Indicates that this struct should be exportable/importable at the DLL layer.

STRUCT_NetSerializeNative

If set, this struct will be serialized using the CPP net serializer

STRUCT_SerializeNative

If set, this struct will be serialized using the CPP serializer

STRUCT_CopyNative

If set, this struct will be copied using the CPP operator=

STRUCT_IsPlainOldData

If set, this struct will be copied using memcpy

STRUCT_NoDestructor

If set, this struct has no destructor and non will be called.

STRUCT_ZeroConstructor

If set, this struct will not be constructed because it is assumed that memory is zero before construction.

STRUCT_ExportTextItemNative

If set, native code will be used to export text

STRUCT_ImportTextItemNative

If set, native code will be used to export text

STRUCT_PostSerializeNative

If set, this struct will have PostSerialize called on it after CPP serializer or tagged property serialization is complete

STRUCT_SerializeFromMismatchedTag

If set, this struct will have SerializeFromMismatchedTag called on it if a mismatched tag is encountered.

STRUCT_NetDeltaSerializeNative

If set, this struct will be serialized using the CPP net delta serializer

STRUCT_PostScriptConstruct

If set, this struct will be have PostScriptConstruct called on it after a temporary object is constructed in a running blueprint

STRUCT_NetSharedSerialization

If set, this struct can share net serialization state across connections

STRUCT_Trashed

If set, this struct has been cleaned and sanitized (trashed) and should not be used

STRUCT_Inherit

Struct flags that are automatically inherited

STRUCT_ComputedFlags

Flags that are always computed, never loaded or done with code generation
