#include "Kismet/BlueprintInstancedStructLibrary.h"

Description

Function library that exposes FInstancedStruct — a type-erased container that can hold an instance of any UScriptStruct — to Blueprint graphs.

Caveats & Gotchas

• The Blueprint nodes (MakeInstancedStruct, SetInstancedStructValue, GetInstancedStructValue) use CustomThunk wildcard pins wired up by the Blueprint compiler; there is no direct C++ equivalent call signature — construct and manipulate FInstancedStruct directly from C++ instead.
• GetInstancedStructValue only succeeds if the InstancedStruct's contained type exactly matches (or is compatible with) the requested output pin type; a mismatch routes to the "Not Valid" exec pin rather than throwing an error.

Access	Type	Name	Description
public	function	UBlueprintInstancedStructLibrary::EqualEqual_InstancedStruct	Checks whether two FInstancedStructs hold the same struct type and equal values, backing the "==" compact node in Blueprint.
public	function	UBlueprintInstancedStructLibrary::GetInstancedStructValue	Extracts the value from an FInstancedStruct into the connected output pin, but only if the pin's type matches the type currently stored inside the instanced struct.
public	function	UBlueprintInstancedStructLibrary::IsInstancedStructValid	Checks whether an FInstancedStruct currently holds a value, exposed to Blueprint as a branching "Is Valid" node.
public	function	UBlueprintInstancedStructLibrary::IsValid_InstancedStruct	Returns whether the given InstancedStruct currently holds a valid struct value.
public	function	UBlueprintInstancedStructLibrary::MakeInstancedStruct	Creates a new FInstancedStruct that holds a copy of the given struct value, capturing its UScriptStruct type along with the data.
public	function	UBlueprintInstancedStructLibrary::NotEqual_InstancedStruct	Checks whether two FInstancedStructs differ in stored type or value, backing the "!=" compact node in Blueprint.
public	function	UBlueprintInstancedStructLibrary::Reset	Clears an FInstancedStruct, optionally reinitializing it as a default-constructed instance of a new struct type.
public	function	UBlueprintInstancedStructLibrary::SetInstancedStructValue	Overwrites the contents of an existing FInstancedStruct with a new struct value, replacing both the stored type and the data.
