)

 Checks if a particular input exists on a given node.
Public function Static UFunction BlueprintCallable, Category bool

IsAnInput ( const FString& AttributeKey
)

 Returns true if the attribute key is associated with an input (starts with "Inputs:").
Public function Static UFunction BlueprintCallable, Category FString

MakeInputConnectionKey ( const FString& InputName
)

 Makes an attribute key to represent a node being connected to an input (ie: Inputs:InputName:Connect).
Public function Static UFunction BlueprintCallable, Category FString

MakeInputName ( const FString& InputKey
)

 From an attribute key associated with an input (ie: Inputs:InputName:Value), retrieves the input name from it.
Public function Static UFunction BlueprintCallable, Category FString

MakeInputValueKey ( const FString& InputName
)
