    • defaultDataModelConversion

      public static Map<String,Object> defaultDataModelConversion(Map<String,Object> dataModel)
      Default data model conversion Only basic types will be used : String, Number, Boolean, Array, Object as Map. For instance the object : 
       
          class Vehicle {
             private String plate;
             private int age;
             public Vehicle(int age, String plate) {
                 this.age = age;
                 this.plate = plate;
            }
             public String getPlate() { return plate; }
             public int getAge() { return age; }
             @Override
             public String toString() {
                return "Vehicle{age="+age+", plate='"+plate+"'}";
             }
         }
         Map<String, Object> dataModel = new HashMap<>();
         dataModel.put( "vehicle", new Vehicle( 10, "AA780BB" ) );
         Map<String, Object> jsonStyleDataModel = EvalScriptWithJsonDataModel.defaultDataModelConversion( dataModel );
         log.info( "originalDataModel : {}", dataModel );
         log.info( "jsonStyleDataModel : {}", jsonStyleDataModel );
      will result in : originalDataModel : {vehicle=Vehicle{age=10, plate='AA780BB'}} jsonStyleDataModel : {vehicle={plate=AA780BB, age=10}}
      Parameters:
      dataModel - the data model to convert
      Returns:
      the data model converted to map of simple types
