Detailed Description

There are three types of module in a transformation chain: Source, Transform, and Sink.

The ideal usage of the transformation would be:

source(...) >> transform1(...) >> transform2(...) >> sink(...);

When error happens in a module, the module will throw out a transform::Error, one can get the location of the module through the getIndex() method of transform::Error.
