ULimenSavesHandler

Overview

ULimenSavesHandler is an abstract class responsible for gathering and serializing gameplay actors implementing ILimenSaveObjectInterface. It stores serialized data locally and provides methods to save and load this data. The class uses recursive serialization, meaning any UPROPERTY marked with SaveGame inside it will also be serialized.

Properties

Type	Name	Access	Description
TWeakObjectPtr	WorldContext	Private	Weak pointer to the current world context.

Functions

Return Type	Signature	Description
bool	DoesListContainDuplicatedDeterministicIds(TArray & InData) const	Checks if there are any duplicated deterministic IDs in the provided array of `FActorSaveData`. Logs warnings and errors as necessary.
bool	ShouldSaveData() const override	Always returns true, indicating that data should be saved.
bool	ShouldLoadData() const override	Always returns true, indicating that data should be loaded.
void	PreDataSaved() override	Empty implementation for pre-save logic.
void	PostDataSaved() override	Empty implementation for post-save logic.
void	PreDataLoaded() override	Empty implementation for pre-load logic.
void	PostDataLoaded() override	Empty implementation for post-load logic.
FName	GetUniqueDeterministicId() const override	Returns `NAME_None`, indicating no unique deterministic ID is available.
bool	SaveDataFrom(UWorld* World)	Sets the world context and returns true if successful.
bool	LoadDataTo(UWorld* World)	Sets the world context and returns true if successful.
UWorld*	GetWorld() const override final	Returns the current world context, asserting that it has been set before calling this method.

Usage & Implementation Notes

Threading Constraints: None.
Replication Requirements: None.
Memory Lifetime Management: The WorldContext is managed using a weak pointer to avoid memory leaks.
Initialization Dependencies: The world context must be set via SaveDataFrom or LoadDataTo before calling any methods that require it.
