/*! \brief The LocalResourceProvider class provides a ResourceProvider
|
|
* implementation which serves data from local files.
|
|
*
|
|
* This class crawls a given directory and provides a ResourceDB with all
|
|
* retrieved information inside. Additionally it monitors all (sub-)directories
|
|
* for changes and immediately updates the database. #fetchData() simply reads
|
|
* the according local file.
