A typical cfwddx tag used to convert a CFML query object to WDDX looks like the following:

<cfwddx action="cfml2wddx" input="#MyQueryObject#" output="WddxTextVariable">

In this example, MyQueryObject is the name of the query object variable, and WddxTextVariable is the name of the variable in which to store the resulting WDDX XML.
