Foil 7 Parts of the JavaBean Brew

From Javabeans Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Nancy McCracken, Wojtek Furmanski


1 A JavaBean is "just" a Java Object which is part of some application for the end-user, i.e. it does not implement any particular class or interface.
2 JavaBeans implement the JDK1.1 event linkage mechanism for exchanging changes in values of properties and hence invoking responses to these changes.
3 JavaBeans implement JDK1.1 Object Serialization to represent JavaBeans in "databases" (disk files) and hence define JavaBeans as persistent objects
4 There are a set of naming conventions called the "JavaBean Framework" or "Design Patterns"
  • This is different from OOP Design Patterns.
5 These patterns are "discovered" automatically by the "introspection" capability of the reflection API.
