A flow engine is an application that executes a flow consisting of several linked rules, in this case against some incoming data (a JSON string that can be parsed to a JavaScript object literal).
Each rule should contain (at least)
- An ID (unique within the flow, required)
- A rule that will be run against the incoming json data. This is a function that takes a parameter and returns a boolean result. Each function should be called with the same incoming data (the JS object literal)
- An ID of the rule to execute if the function returns true (
true_id) - An ID of the rule to execute if the function returns false (
false_id)
Pass an object (an example of an object and a rule is given below) to the created flow.
The execution will end when a null is provided for the true_id (and the function returns true) or when null is provided for the false_id (and the function returns false).
Additionally, the flow engine (with the provided rule-set) should not be circular.
