/**
 * @brief Represents a problem as one unit with the IProblem interface so can be used with anything that can handle IProblem.
 *
 * You should have it wrapped in an IProblem::Ptr which is a shared pointer for it.
 * It is basically a mirror of DUChain's Problem class.
 * However that class is strongly coupled with DUChain's internals due to DUChain's needs (special serialization).
 *
 * Usage example:
 * @code
 * IProblem::Ptr problem(new DetectedProblem());
 * problem->setSource(IProblem::Plugin);
 * problem->setSeverity(IProblem::Warning);
 * problem->setDescription(QStringLiteral("Warning message"));
 * problem->setExplanation(QStringLiteral("Warning explanation"));
 *
 * DocumentRange range;
 * range.document = IndexedString("/path/to/source/file");
 * range.setBothLines(1337);
 * range.setBothColumns(12);
 * problem->setFinalLocation(range);
 * @endcode
