CXP page execution Foundation

The primary task of the cxc-builder transpilation process is to generate the prg source code of a Xbase++ class for each CXP file. In fact, all HTML markup defined in your view is injected into the :render() method of the generated Xbase++ class. The same is true for your Xbase++ code. The resulting Xbase++ class is derived from the CxpAbstractPage class.

Whenever a request for a CXP page is received by the cxp-worker, the associated DLL is loaded, and an instance of the page class is created. The following outlines the order of execution of the methods of the generated page class.

1 :load() is executed right after the DLL was loaded, and before the first instance of the page class is created.

2 :render() is executed for creating the content of the view.

3 :unload() is executed before the cxp-worker process shuts down. Repeated page requests do not lead to a new load/unload cycle.
