Visual builders enable you to develop basic or complex applications without writing a single line of code. Just place the desired telephony beans onto the work area and graphically connect them. The visual builder makes the connections for you (linking an event of a source bean to a method on a target bean) by automatically generating the required adapter code. When you run the application, the adapter code listens for the event from the source bean and then invokes the method on the target bean.
The four most common ways to connect telephony beans in a visual builder are shown in Figure 3, Figure 4, Figure 5, and Figure 6. These figures illustrate:
