Syntax

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; Note: 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

	Name	Description
	UEdGraph ( const FObjectInitializer& ObjectIn... )

Overridden from UObject

	Name	Description
void	BuildSubobjectMapping ( UObject* OtherObject, TMap< UObject, UObject ... )	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.
void	PostInitProperties()	Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
void	PostLoad()	Do any object-specific cleanup required immediately after loading an object.
void	Serialize ( FStructuredArchiveRecord Record )	Handles reading, writing, and reference collecting using FArchive.
