Class MyDataEnvironmentManager

java.lang.Object

de.fraunhofer.iese.mydata.MyDataEnvironmentManager

public final class MyDataEnvironmentManager
extends Object

MyDataEnvironmentManager handles the IMyDataEnvironment, whether it is local or cloud.

Simple usage example (local-mode, manual init/config):

   
     MyDataEnvironmentManager.constructDefaultEnvironment().initializeLocal(new SolutionId("urn:solution:mysolution"), "Europe/Berlin", 4, true, null);
     IMyDataEnvironment myDataEnvironment = MyDataEnvironmentManager.getDefaultEnvironment();
     myDataEnvironment.registerLocalPxp("mailpxp", new MailPxp(...));
     PolicyId policyId = myDataEnvironment.getPmp().addPolicy(new Policy(...));
     myDataEnvironment.getPmp().deployPolicy(policyId);
     Event event = new EventBuilder("mysolution", "read").withParameter("text", "Hello World", String.class).getEvent();
     try{
       myDataEnvironment.getPep().enforce(event); // use of a provided default PEP
       System.out.println(event.getValueForName("text")); // access to the enforced event/data
     } catch (InhibitException e){ // handling of InhibitException
       System.out.println("Inhibited");
     } catch (EvaluationUndecidableException e) { // handling of EvaluationUndecidableException
       System.out.println("EvaluationUndecidable");
     } catch (IOException e){ // handling of IOException
       System.out.println("IOException");
     }
