Using ALV display variants using class CL_ALV_VARIANT

Hello,

I am working on developing an ALV report and I want to limit the use of Function calls and Forms. I would rather use Method calls using classes, using a more ABAP Object-Oriented approach. Searching for any documentation on the class on SDN has proved fruitless. So, my question is, has anyone had any success implementing display variants on an ALV report using the CL_ALV_VARIANT class methods?
