The visual interface allows inspection of and implementation of both individual beans and their linkage . This visual construction of linkage allows one to form nontrivial programs with multiple communicating components
|
Apart from the event mechanism which is a communication/linkage mechanism, ComponentWare (and JavaBeans in particular) "just" give a set of universal rules (needed for interoperability) for rather uncontroversial (albeit good) object-oriented and visual programming practices
-
Hiding of properties which can only be accessed by methods (which must have special names)
-
Display of these properties (as given by methods)
|
Javabeans expose the interesting events and properties and the user can use this in a design environment such as Visual Café to decide how to share these exposed elements
