DebugQuery
initialize a query with a name, columns, and a data set.
To use the debugging classes:
1. Create a
testbed for your CFX.
2. Within the

test.
3. Create an instance of your Java CFX and call its

4. Call the
request, including content generated, variables set, queries created, and so forth.
Once you have implemented a main method as described above, you can debug your
Java CFX using an interactive, single-step debugger. Just specify your Java CFX class as
the

The following example demonstrates the use of the debugging classes.
