class UEdGraph : public UObject

Variables

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

Constructors
