Question

Is there a way in java we can convert an expression (xml or any other) to logical operations.

for example I have a property

prop01=Achivment:APPCom,done&&TODO:getforecast,!done;Achivement done

is there a way I convert it to java code like

    Map userData = getUserData();

    Map achivements = userData.get("achivements");
    Map TODOs = userData.get("TODOs");

    String achiv = achivements.get("APPCom");
    String todo = TODOs.get("getforecast");

    if(achiv == "done" && todo != "done")
        system.out.println("Achivement done"); // part after ; in expression

any third party available for this kind of task?

Was it helpful?

Solution

I don't think this can be done with any third party library directly. You may need to use some library like Antlr to write a translator to translate from your expression to your Java code.
