Functions

  Type Name Description
Public function void

AddObjectToDelete ( UObject* InObject
)

 Add an object to the list of pending deleted assets, this will invalidate the scanning state.
Public function Const bool Returns true if it is valid to delete the current objects with no problems.
Public function Const bool Returns true if it is valid to force the delete of the current assets.
Public function Const bool Returns true if it's valid to replace the references of the pending deleted objects.
Public function Const bool

CanReplaceReferencesWith ( const FAssetData& InAssetData
)

 Returns true if it is valid to force the delete of the current assets with the provided asset.
Public function void Deletes any source content files referenced by the assets
Public function bool Performs the delete if it's possible.
Public function bool Performs a force delete on the pending deleted assets if possible.
Public function bool

DoReplaceReferences ( const FAssetData& ReplaceReferencesWith
)

 Performs the replace references action if possible with the provided asset.
Public function Const const TSet< FName > & Gets the packages of the assets on disk that reference the pending deleted objects; won't be accurate until the scanning process completes.
Public function Const int32 Gets the number of objects successfully deleted.
Public function Const const TArray< TSharedPtr< FPendingDelete > > * Returns the pending deleted assets.
Public function Const const TMap< FString, int32 > & Returns a map of currently discovered source content files, and the number of times they are referenced by non-deleted assets
Public function Const float Gets the 0..1 progress of the scanning.
Public function Const FText Gets the current text to display for the current progress of the scanning.
Public function Const EState Returns the current state of the deletion process
Public function Const bool Goes to the next actor in the loaded level if it is available
Public function Const bool Check whether we have any source files residing under monitored, mounted paths to delete
Public function Const bool Is any of the pending deleted assets being referenced in memory.
Public function Const bool Is any of the pending deleted assets being referenced in the undo stack.
Public function Const bool

IsAssetInPendingDeletes ( const FName& PackageName
)

 Returns true if the package is one of the pending deleted assets.
Public function Const bool

IsObjectInPendingDeletes ( const UObject* InObject
)

 Returns true if the object is one of the pending deleted assets.
Public function FOnStateChanged &  
Public function void

Tick ( const float InDeltaTime
)

 Ticks the delete model which does a little work before returning so that we don't completely block when deleting a lot of things.

Classes

  Type Name Description
Public class FOnStateChanged Fires whenever the state changes.  

Enums

  Type Name Description
Public enum EState States used to manage the async deletion process.
