Inspecting java variable

I'm writing a plugin to inspect some elements of my code.

I need to make a reference of the object "vo" to the argument "TABLE" of JapeWrapper.dao;

The goal is to validate that COLUMN2 belongs to the TABLE;

<code>

JapeWrapper jape = JapeWrapper.dao ("TABLE");

DynamicVO vo = jape.findOne ("COLUMN1 =?", "Anything");

String column = vo.asString ("COLUMN2"); // "vo" is an object to access "TABLE"

</code>

Someone have an idea?
