\class CppEditor::BaseEditorDocumentParser
\brief The BaseEditorDocumentParser class parses a source text as
precisely as possible.
It's meant to be used in the C++ editor to get precise results by using
the "best" project part for a file.
Derived classes are expected to implement updateImpl() this way:
\list
\li Get a copy of the configuration and the last state.
\li Work on the data and do whatever is necessary. At least, update
the project part with the help of determineProjectPart().
\li Ensure the new state is set before updateImpl() returns.
\endlist
