The IsNull node outputs True if the input reference datatype is null, otherwise False.
Usage
When spawned from the node browser, this node accepts the object datatype by default. However, this node can be overloaded to accept any reference datatype if an appropriate wire is connected.
The NotNull (LogiX node) works in the opposite way.
Examples
Using a String as an example. The string being empty outputs as True
When it's no longer empty, it'll output Fales
