Inputs

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.
