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.
