class UEditorValidatorSubsystem : public UEditorSubsystem

Remarks

UEditorValidatorSubsystem manages all the asset validation in the engine. The first validation handled is UObject::IsDataValid and its overridden functions. Those validations require custom classes and are most suited to project-specific classes. The next validation set is of all registered UEditorValidationBases. These validators have a function to determine if they can validate a given asset, and if they are currently enabled. They are good candidates for validating engine classes or very specific project logic.

Variables

bool	bAllowBlueprintValidators	Specifies whether or not to allow Blueprint validators
bool	bValidateAssetsWhileSavingForCook	Specifies whether or not to validate assets on save when saving for a cook
bool	bValidateOnSave	Whether it should validate assets on save inside the editor
TArray< FDirect...	ExcludedDirectories	Directories to ignore for data validation. Useful for test assets
TArray< FName >	SavedPackagesToValidate	List of saved package names to validate next frame
TMap< UClass &#...	Validators

Functions

	Name	Description
void	AddValidator ( UEditorValidatorBase* InValida... )	Adds a validator to the list, making sure it is a unique instance
void	CleanupValidators()
EDataValidat...	IsAssetValid ( FAssetData& AssetData, TArray< FText >& ValidationErrors, TArray< FText >& ValidationWarning... )
EDataValidat...	IsObjectValid ( UObject* InObject, TArray< FText >& ValidationErrors, TArray< FText >& ValidationWarning... )

void	RegisterBlueprintValidators()
void	ValidateAllSavedPackages()	Handles validating all pending save packages
int32	ValidateAssets ( TArray< FAssetData > AssetDataList, bool bSkipExcludedDirectories, bool bShowIfNoFailures )	Called to validate assets from either the UI or a commandlet
void	ValidateOnSave ( TArray< FAssetData > AssetDataList )	Called to validate from an interactive save
void	ValidateSavedPackage ( FName PackageName )	Schedule a validation of a saved package, this will activate next frame by default so it can combine them
