namespace Poco {

class Util_API FilesystemConfiguration: public AbstractConfiguration
An implementation of AbstractConfiguration that stores configuration data
in a directory hierarchy in the filesystem.
Every period-separated part of a property name is represented
as a directory in the filesystem, relative to the base directory.
Values are stored in files named "data".
All changes to properties are immediately persisted in the filesystem.
For example, a configuration consisting of the properties
logging.loggers.root.channel.class = ConsoleChannel
logging.loggers.app.name = Application
logging.loggers.app.channel = c1
logging.formatters.f1.class = PatternFormatter
logging.formatters.f1.pattern = [%p] %t
is stored in the filesystem as follows:
logging/
loggers/
root/
channel/
class/
data ("ConsoleChannel")
app/
name/
data ("Application")
channel/
data ("c1")
formatters/
f1/
class/
data ("PatternFormatter")
pattern/
data ("[%p] %t")
{
public:
FilesystemConfiguration(const std::string& path);
Creates a FilesystemConfiguration using the given path.
All directories are created as necessary.
void clear();
Clears the configuration by erasing the configuration
directory and all its subdirectories and files.
