Halt evaluation onSuccess

[dcparsons]

Hello.

I am wondering if there is a way to halt rule evaluation once the engine has found a matching rule. I have played around with a combination of rules and operators but it seems like the engine evaluates all rules in a workflow. As an example:

[
  {
    "WorkflowName": "WelcomeEmail",
    "Rules": [
      {
        "RuleName": "Cleveland",
        "SuccessEvent": "10",
        "ErrorMessage": "Cleveland rule failed",
        "ErrorType": "Error",
        "RuleExpressionType": "LambdaExpression",
        "Expression": "input1.State == \"OH\" AND input1.city == \"Cleveland\""
      },
      {
        "RuleName": "GeneralOhio",
        "SuccessEvent": "20",
        "ErrorMessage": "Ohio rule failed.",
        "ErrorType": "Error",
        "RuleExpressionType": "LambdaExpression",
        "Expression": "input1.State == \"OH\"
      }
    ]
  }
]

In the example above any input that causes the first rule to be true will also cause the second rule to be true. The behavior I want is basically an if/else so:

if(obj.State == "OH" && obj.City == "Cleveland") {
     //do one thing
}
else if(obj.State == "OH") { 
     //do another thing
}

Is the functionality I am describing in the rules engine?

It is not possible at workflow level but is available at nest rule level.
You can achieve it by modifying the workflow a little.

[
  {
    "WorkflowName": "WelcomeEmail",
    "Rules": [
        {
            "RuleName":"CheckState",
            "Operator": "Or",
            "Rules":[
                {
                    "RuleName": "Cleveland",
                    "SuccessEvent": "10",
                    "ErrorMessage": "Cleveland rule failed",
                    "ErrorType": "Error",
                    "RuleExpressionType": "LambdaExpression",
                    "Expression": "input1.State == \"OH\" AND input1.city == \"Cleveland\""
                  },
                  {
                    "RuleName": "GeneralOhio",
                    "SuccessEvent": "20",
                    "ErrorMessage": "Ohio rule failed.",
                    "ErrorType": "Error",
                    "RuleExpressionType": "LambdaExpression",
                    "Expression": "input1.State == \"OH\""
                  }
            ]
        }
    ]
  }
]

And you need to set the following ReSettings in the rules engine:

var reSettings = new ReSettings(){
   NestedRuleExecutionMode = NestedRuleExecutionMode.Performance
}

var ruleEngine =  new RulesEngine(workflows,logger,reSettings);
