Not
Boolean logic
Pure
Not
Value
false
Result
Description
Pure function returning the logical negation of a boolean.
When to use
Use Not to invert a boolean before passing it to Branch or another logic node. It is most useful when a downstream node expects a positive condition but your source produces the inverse — for example, negating Is empty? to get “is not empty”. For compound negation such as NOT (A AND B), combine Not with And or Or.
Pins
Input pins
| Pin | Type | Default | Notes |
|---|---|---|---|
| Value | boolean | false | The boolean to negate. |
Output pins
| Pin | Type | Notes |
|---|---|---|
| Result | boolean | True if value is false; false if value is true. |
Example
Proceed only when a string value is not empty. Wire the Result output of Is empty? into the Value input of Not to flip the polarity. Connect the Result output of Not to the Condition input of Branch — the True execution output now fires only when the text has at least one character.
