		UNiagaraNodeOp ( const FObjectInitializer& ObjectInitializer )

	Type	Name	Description
	void	HandleStaticInputPinUpgrade ( UEdGraphPin* InputPin )
	void	HandleStaticOutputPinUpgrade ()

Type	Name	Description
bool	AllowDynamicPins ()
bool	AllowNiagaraTypeForAddPin ( const FNiagaraTypeDefinition& InType )	Determine whether or not a Niagara type is supported for an Add Pin possibility.
bool	CanMovePin ( const UEdGraphPin* Pin, int32 DirectionToMove )	Called to determine if a pin can be moved by the user. Negative values for up, positive for down.
bool	CanRemovePin ( const UEdGraphPin* Pin )	Called to determine if a pin can be removed by the user.
void	OnNewTypedPinAdded ( UEdGraphPin*& NewPin )	Called when a new typed pin is added by the user.
void	OnPinRenamed ( UEdGraphPin* RenamedPin, const FString& OldPinName )	Called when a pin is renamed.

Type	Name	Description
void	BuildParameterMapHistory ( FNiagaraParameterMapHistoryBuilder& OutHistory, bool bRecursive, bool bFilterForCompilation )	Adds the current node information to the parameter map history
void	Compile ( FTranslator* Translator, TArray< int32 >& Outputs )
bool	GenerateCompileHashForClassMembers ( const UClass* InClass, FNiagaraCompileHashVisitor* InVisitor )	Go through all class members for a given UClass on this object and hash them into the visitor.
TOptional< float >	GetCompactModeFontSizeOverride ()
FText	GetCompactTitle ()	If this does not return an empty title, compact mode will be activated putting the text into the center of the node.
ENiagaraNumericOutputTypeSelectionMode	GetNumericOutputTypeSelectionMode ()	Gets which mode to use when deducing the type of numeric output pins from the types of the input pins.
void	OnPostSynchronizationInReallocatePins ()
bool	RefreshFromExternalChanges ()	Refreshes the node due to external changes, e.g. the underlying function changed for a function call node.
FNiagaraTypeDefinition	ResolveCustomNumericType ( const TArray< FNiagaraTypeDefinition >& NonNumericInputs )
bool	ShouldShowPinNamesInCompactMode ()

Type	Name	Description
void	AllocateDefaultPins ()	Allocate default pins for a given node, based only the NodeType, which should already be filled in.
FText	GetNodeTitle ( ENodeTitleType::Type TitleType )	Gets the name of this node, shown in title bar
FLinearColor	GetNodeTitleColor ()	Gets the draw color of a node's title bar
FText	GetTooltipText ()	Gets the tooltip to display when over the node
void	OnPinRemoved ( UEdGraphPin* InRemovedPin )	Called when a pin is removed
void	PinConnectionListChanged ( UEdGraphPin* Pin )	Called when the connection list of one of the pins of this node is changed in the editor
void	PinTypeChanged ( UEdGraphPin* Pin )	Called when one of the pins of this node has had its' pin type changed from an external source (like the SPinTypeSelector in the case of kismet)
