Syntax

UCLASS (BlueprintType, MinimalAPI)  
class UInterchangeFactoryBaseNode : public UInterchangeBaseNode

Remarks

This struct is used to store and retrieve key-value attributes. The attributes are stored in a generic FAttributeStorage that serializes the values in a TArray64. See UE::Interchange::EAttributeTypes to know the supported template types. This is an abstract class. This is the base class of the Interchange node graph format; all classes in this format should derive from this class.

Variables

  Type Name Description
Protected variable TMap< UClass *, TArray< UE::Interchange::FApplyAttributeToAsset > > ApplyCustomAttributeDelegates This array holds the delegate to apply the attribute that has to be set on an UObject.
Protected variable UE::Interchange::TArrayAttributeHelper< FString > FactoryDependencies Those dependencies are used by the Interchange parsing task to make sure the assets are created in the correct order.
Protected variable TMap< UClass *, TArray< UE::Interchange::FFillAttributeToAsset > > FillCustomAttributeDelegates

Public function Const UFunction BlueprintCallable, Category void

GetFactoryDependency ( const int32 Index,
FString& OutDependency
)

 Retrieve one dependency for this object.
Public function Virtual Const UClass * Return the UClass of the object we represent, so we can find the factory/writer.
