IsNull (LogiX node)

IsNull
Inputs
	Object	Instance
Outputs
	Bool	*

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
