Loop Counter Branching

N2FE Flow Operation - Loop Counter Branching

The LoopCounterBranching will inspect the stored value of a provided counter and will select the appropriate exit according to if:

The LoopCounterBranching operation has exactly two exits.

Config Parameters

The LoopCounterBranching operation config attributes are as follows.

Parameter Type Description
buffer User Buffer [Required] This must be the Name of a User Buffer (e.g. user.counter1 or user.counter2) which will be used for branching. See the notes on Buffer Names in the Flow Introduction documentation. The GUI may allow free-form entry for the user buffer name, or may restrict it to pre-determined values.
limit Integer [Required] This is the limit value. It must be an integer greater than or equal to zero.

Example Operation

Here is an example LoopCounterBranching operation in JSON representation.

    {
        "id": 5,
        "type": "LoopCounterBranching",
        "base_node": 1,
        "config": {
            "buffer": "user.counter1",
            "limit": 3
        },
        "exits": [ 4, 17 ]
    }

In this example, if the value of the buffer user.counter1 is greater than or equal to three, processing will proceed down exit index 1 to operation ID 17. Otherwise processing will continue down exit index 0 to operation ID 4.

Exits

There are exactly two exits for every LoopCounterBranching.

Exit Index Name Description
0 Not-Reached Exit [Required] This exit is used if the counter value has not yet reached the configured limit, i.e. if it is strictly less than the limit.
`1` Limit-Reached Exit [Required] This exit is used if the counter value has reached the configured limit, i.e. if it is greater than or equal to the limit.
