Syntax

class FTransactionObjectEvent

Remarks

Transaction object events.

Transaction object events are used to notify objects when they are transacted in some way. This mostly just means that an object has had an undo/redo applied to it, however an event is also triggered when the object has been finalized as part of a transaction (allowing you to detect object changes).

Constructors

	Name	Description
	FTransactionObjectEvent()
	FTransactionObjectEvent ( const FGuid& InTransactionId, const FGuid& InOperationId, const ETransactionObjectEventType I..., const FTransactionObjectDeltaChange..., const TSharedPtr< ITransactionObjec..., const FName InOriginalObjectPackage..., const FName InOriginalObjectName, const FName InOriginalObjectPathNam..., const FName InOriginalObjectOuterPa..., const FName InOriginalObjectExterna..., const FName InOriginalObjectClassPa... )
