Functions

	Name	Description
void	AddPins ( FKismetCompilerContext& CompilerCo..., UK2Node_CallFunction* Evaluate... )	Add additionnal pin that the evaluate function would need
TSubclassOf<...	GetDefaultRolePinValue()
FName	GetEvaluateFunctionName()	Get the name of the UFunction we are trying to build from
UEdGraphPin ...	GetFrameNotAvailablePin()	Get the exec output pin for when no frame is available for the desired role
UScriptStruc...	GetLiveLinkRoleOutputFrameStructType()
UScriptStruc...	GetLiveLinkRoleOutputStructType()	Get the type that the Live Link Role evaluates to to return
UEdGraphPin ...	GetLiveLinkRolePin()	Get the Live Link Role input pin
UEdGraphPin ...	GetLiveLinkSubjectPin()	Get the Live Link Subject input pin
UEdGraphPin ...	GetResultingDataPin()	Get the result output pin
UScriptStruc...	GetReturnTypeForOutputDataStruct()	Get the return types of our struct
UEdGraphPin ...	GetThenPin()	Get the then output pin
bool	IsRoleValidForEvaluation ( TSubclassOf< ULiveLinkRole > InRole... )	Verify if selected role class is valid for evaluation
void	RefreshDataOutputPinType()	Queries for the authoritative return type, then modifies the return pin to match
void	SetPinToolTip ( UEdGraphPin& InOutMutatablePin, const FText& InPinDescription )	Takes the specified "MutatablePin" and sets its 'PinToolTip' field (according to the specified description)
void	SetReturnTypeForOutputStruct ( UScriptStruct* InClass )	Set the return type of our structs

Overridden from UK2Node

	Name	Description
void	EarlyValidation ( FCompilerResultsLog& MessageLog )	This function if used for nodes that needs CDO for validation (Called before expansion)
void	ExpandNode ( FKismetCompilerContext& CompilerCo..., UEdGraph* SourceGraph )	Expands a node while compiling, which may add additional nodes or delete this node
void	GetMenuActions ( FBlueprintActionDatabaseRegistrar&... )	Replacement for GetMenuEntries().
FText	GetMenuCategory()	Override to provide a default category for specific node types to be listed under.
bool	IsConnectionDisallowed ( const UEdGraphPin* MyPin, const UEdGraphPin* OtherPin, FString& OutReason )
bool	IsNodeSafeToIgnore()	Query if this is a node that is safe to ignore (e.g., a comment node or other non-structural annotation that can be pruned with no warnings).
void	NotifyPinConnectionListChanged ( UEdGraphPin* Pin )	Called when the connection list of one of the pins of this node is changed in the editor, after the pin has had it's literal cleared
void	PostReconstructNode()	Called at the end of ReconstructNode, allows node specific work to be performed
void	PreloadRequiredAssets()	Called before compilation begins, giving a blueprint time to force the linker to load data
void	ReallocatePinsDuringReconstruction ( TArray< UEdGraphPin* >& OldPi... )	Reallocate pins during reconstruction; by default ignores the old pins and calls AllocateDefaultPins() If you override this to create additional pins you likely need to call RestoreSplitPins to restore any pins that have been split (e.g. a vector pin split into its components)

Overridden from UEdGraphNode

	Name	Description
void	AllocateDefaultPins()	Allocate default pins for a given node, based only the NodeType, which should already be filled in.
FSlateIcon	GetIconAndTint ( FLinearColor& OutColor )
FText	GetTooltipText()	Gets the tooltip to display when over the node
void	PinDefaultValueChanged ( UEdGraphPin* Pin )	Called when the DefaultValue of one of the pins of this node is changed in the editor
