Description

An application source file contains XML that describes a view that will be instantiated when the application is loaded. These XML elements are called view templates, and occur either directly within the document root, or within another view template. A root view template is a view template that occurs directly within the document root. The interface compiler compiles each root view template into ActionScript bytecodes that, when executed, create an instance of the object that the XML element describes. It does this by appending to the output file instructions to push a succint description of the XML hierarchy onto the stack, followed by a call to LzInstantiateView (below) with the runtime representation of the root view template as its argument. The format of the runtime representation is documented in the Javadoc for org.openlaszlo.ic.ScriptCompiler.xmlToScript. In brief, an XML element is compiled to a runtime object with the following attributes: tagName: The element, or tag name (e.g. "window") attrs: An object whose properties are attributes, e.g. {title: "Contacts", x: 10, y: 20} children: An array of child elements.
