QDeclarativeDebugtrace API documentation

[fanda]

Hi,

I'm writing library with QtCreator profiler support. I've found pretty simple and private API QDeclarativeDebugTrace. After some try/mistakes I've made it working, but I still have couple of questions:

Can be ranges nested?
If so, what is a meaning of ranges nesting?
Can ranges of the same RangeType overlap?
Can ranges of different RangeType overlap?
Is where any documentation or document describing concept of API?

I know that API is private and will change in Qt5 but it works well and I'm prepared to rewrite my code when API changes come.

Thanks for any hint.
