Java Beans Question: Download Questions PDF
JavaBeans has mechanisms like bound properties for data transfer between components. Why is the InfoBus necessary?
Answer:
JavaBeans mechanisms, such as bound properties, are very useful in cases where the type of data to be communicated can be hard-coded into the source and target components. The InfoBus adds additional features required for more dynamic data interchange. These can be cases where communication is driven by the content of the data and where the nature of the data to be exchanged is determined at runtime.
