There are three types of behaviors typical of embedded systems:
Although the IBM® Rational® Rhapsody® graphical user interface directly supports only simple and reactive behaviors, you can implement all three types. To address the continuous time aspects, you can reference or include any code you are currently using to express continuous behavior in any of the operations defined within Rational Rhapsody.
This means that if you are defining your continuous behavior elements manually, you can continue to do so. If you are using another tool to define your continuous behavior and that tool generates code, you can include that code.
