Number Matching

N2FE Flow Operation - Number Matching

The NumberMatching node takes a value from a source user buffer and performs a match against a specified set of match rule patterns.

The NumberMatching operation has three exits.

The exits are:

Number Found (the source user buffer value matched a match rule pattern).
Number not Found (the source user buffer value did not match any match rule pattern).
Number is Undefined (the source user buffer value is not defined).

Config Parameters

The NumberMatching operation config attributes are as follows.

Parameter	Type	Description
`match_rules`	List of Strings	[Required] The `match_rules` parameter is a List of Strings that defines a list of match patterns to use when comparing the value stored in the source user buffer. The expected format of each match rule is the same as an NCC search pattern.
`source_buffer`	User Buffer	[Required] This must be the Name of a User Buffer (e.g. `user.postcode` or `user.input`) from which the value to compare will be retrieved. 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.

Example Operation

Here is an example NumberMatching operation in JSON representation.

    {
        "id": 5,
        "type": "NumberMatching",
        "base_node": 1,
        "config": {
            "match_rules": [
                "1??",
               	"2??",
                "3??"
            ]
            "source_buffer": "user.follow_me"
        },
        "exits": [ 8, 9, 10 ]
    }

Exits

There are always exactly three exits for an NumberMatching operation.

Exit Index	Name	Description
1	Number Found	[Required] This exit is followed if the value in the source user buffer matched a defined rule pattern.
2	Number not Found	[Required] This exit is followed if the value in the source user buffer did not match any defined match rule pattern.
3	Number is Undefined	[Required] This exit is followed if the source user buffer did not contain a value.
