The eventloop of Bananas

The eventloop of a Banana is intialized by the run() member function. Without this, the Banana will not respond to requests from clients. The eventloop then waits until a request is received from a client calling a function on that object. An event can also be posted by a timer function (currently not implemented).

When an event is posted, the event handler dispatchs it to one of three possible events. These events are: 1. a function is called; 2. the value of a property is requested or 3. the value of a property is set.

Handling function calls

When an function event occurs, the dispatcher calls the member function of the class. In the examples below you can see how a functioncall is used from a client side script. Both the clientside script and Banana are shown.

Example 4-2. Calling a Banana method
<?php /* Make a connection to SRM */ $srm = new SRM ('srm.vl-srm.net', 7778); $dice = new SRMApp ($srm, 'Dice'); /* Call the roll() function of the Banana */ echo $dice->roll(); ?>

Example 4-3. Processing a Banana method
<?php /* Class definition */ class Dice extends Banana { function roll() { return rand (1, 6); } } /* Start up the Banana */ $banana = new Dice; $banana->run(); ?>
