FNiagaraComp...	GetCompileHash ( ENiagaraScriptUsage InUsage, const FGuid& InUsageId )
void	GetLinkedPositionTypeInputs ( const TArray< FNiagaraVariable >& ..., TSet< FNiagaraVariable >& OutLinke... )	Checks if any of the provided variables are linked to function inputs of position type data
bool	IsSynchronized ( const FGuid& InChangeId )	Determines if the input change id is equal to the current source graph's change id.
void	MarkNotSynchronized ( FString Reason )	Enforce that the source graph is now out of sync with the script.
FOnChanged &	OnChanged()
void	PostLoadFromEmitter ( UNiagaraEmitter& OwningEmitter )	Allows the derived editor only script source to handle a post load requested by an owning emitter.
TSharedPtr< ...	PreCompile ( UNiagaraEmitter* Emitter, const TArray< FNiagaraVariable >& ..., TArray< TSharedPtr< FNiagaraCompile..., bool bClearErrors )	Cause the source to build up any internal variables that will be useful in the compilation process.
void	RefreshFromExternalChanges()
void	RenameGraphAssignmentAndSetNodePins ( const FName OldName, const FName NewName )	Rename all graph assignment and map set node pins.
void	SynchronizeGraphParametersWithParameterDefinitions ( const TArray< UNiagaraParameterDefi..., const TArray< UNiagaraParameterDefi..., const TSet< FGuid >& AllDefinition..., INiagaraParameterDefinitionsSubscri..., FSynchronizeWithParameterDefinition... )	Synchronize all source script variables that have been changed or removed from the parameter definitions to all eligible destination script variables owned by the graph.
