Variables

  Type Name Description
Public variable UProperty uint32: 1 bAllowDeletion If true, graph can be deleted from the whatever container it is in.
Public variable UProperty uint32: 1 bAllowRenaming If true, graph can be renamed; Note: Graph can also be renamed if bAllowDeletion is true currently
Public variable UProperty uint32: 1 bEditable If true, graph can be edited by the user
Public variable UProperty FGuid GraphGuid Guid for this graph
Public variable UProperty FGuid InterfaceGuid Guid of interface graph this graph comes from (used for conforming)
Public variable UProperty TArray< TObjectPtr< class UEdGraphNode > > Nodes Set of all nodes in this graph
Public variable UProperty TSubclassOf< class UEdGraphSchema > Schema The schema that this graph obeys
Public variable UProperty TArray< TObjectPtr< class UEdGraph > > SubGraphs Child graphs that are a part of this graph; the separation is purely visual

  Type Name Description
Public function Virtual Const void

BuildSubobjectMapping ( UObject* OtherObject,
TMap< UObject*, UObject* >& ObjectMapping
)

 Given OtherObject (which will be the same type as 'this'), recursively find any matching sub-objects from 'this' that also exist within OtherObject, and add the mappings to ObjectMapping.
Public function Virtual void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
