class UDataprepAsset : public UDataprepAssetInterface

Remarks

A DataprepAsset is an implementation of the DataprepAssetInterface using a Blueprint as the recipe pipeline. The Blueprint is composed of DataprepAction nodes linearly connected.

)

 Rename this object to a unique name, or change its outer.

Classes

  Type Name Description
Public class FDataprepParameterizationStatusForObjectsChanged Event to notify the ui that a Dataprep parametrization was modified This necessary as the ui for the parameterization is only updated by manual event (the ui don't pull new values each frame) Note on the objects param: The parameterized objects that should refresh their ui.  
Public class FOnDataprepActionAssetChange Allow an observer to be notified of an change in the pipeline return The event that will be broadcasted when a object has receive a modification that might change the result of the pipeline  
Public class FOnStepObjectsAboutToBeRemoved Allow an observer to be notified of the removal of some step from the asset  
Public struct FRestrictedToActionAsset
