ProtoFlux:Not Null

NOT Null

Instance

*

Operators

The Not Null node takes in a reference type and returns if the provided reference is not null.

Value types cannot be null, unless using the nullable version of those types. Using value types that are nullables will not work with this node however.

If you want to check if something is null, use the Is Null node instead.

Inputs

Instance (Pseudo-Generic)

The reference to check.

Outputs

* (bool)

Outputs if instance is not null.
