1 The java.beans.BeanInfo interface is used to define everything about a Bean that is not implied by reflection and design patterns
2 extend java.beans.SimpleBeanInfo which defaults all the methods to null which implies that one use reflection
  • this allows one to violate all the design patterns for methods events and properties and supply information by hand!
3 BeanInfo can supply
  • an icon to represent Bean
  • a list of supported properties, events and methods with a short (help) description of them
  • the default property event or method
  • custom property editors for all or some of properties of the Bean
4 BeanDescriptor is one of entities you can get from BeanInfo and this holds overall information about the Bean
