Intra- Application Scripting

Component: At scripting structural level, component is application program or system function provided by OS, etc.

Connector: At scripting structural level, connector is the operator defined by scripting language.

Interface:

Link:

Example: Since JavaScript is the default script language for browsers right now, and its interesting programming way: embedded into HTML file, we try to use describe this structure using xADL2.0.

And copy an example code from our previous one – “Buying items via web”:

<SCRIPT LANGUAGE="JavaScript">
<!-- Beginning of JavaScript -

function MsgBox (textstring) { alert (textstring) }

// - End of JavaScript - -->
</SCRIPT>

</HEAD>

<BODY>

</BODY>
</HTML>

And we have xADL-type structural diagram:
