BREAK

Download Flojoy Studio to try this app

End the iteration of a loop. It should be used in conjunction with conditionals to determine when to break the loop. It is needed to be able to generate 'while loops' in Flojoy (combined with an 'infinite loop'). Params: referred_node : NodeReference This is the specific instance of a LOOP node that you want to break. It is required to differentiate between multiple LOOPs if they exist in the same application. default : DataContainer This node simply requires an input (most likely from the return of a CONDITIONAL node) so that it is executed. Returns: out : None

Python Code
