Bio Objects is a library which can be used as a replacement for Java Beans. Bio Objects are based on Maps (Keys-Values) and you will only need to extend BioObject class and add necessary annotations. Bio Dictionary will be built based on @annotations or xml configuration and will contain all information required for serialization, xml/json parsing etc.

Bio Objects are very useful in conjunction with Bio Expressions where you can write dynamic decision making mechanisms for your application. Such as :

• if car.year_of_production > 2015 and car.engine * 2 < 6000 do this
• if car.fuel_efficiency.checkEUStandard() do this
• if car.calculateHP(car.cylinders, car.engine) > 200 do this
• if 4 <= car.engine.cylinders <= 6 and car.fuel_efficiency < 15.4 do this
• if ?car.producer and car.producer = ['BMW', 'Toyota'] do this (if car object contains a tag producer and it is equal to any of the elements of array.)

Here is simple definition of Bio Object

@BioObj
public class Car extends BioObject {

  @BioTag(type="Integer")
  public static final String YEAR_OF_PRODUCTION = "year_of_production" ;
  
  @BioTag(type="String")
  public static final String PRODUCER = "producer" ;
  
  @BioTag(type="Double")
  public static final String FUEL_EFFICIENCY = "fuel_efficiency" ;
}
