A dirty bit to indicate wheter the clients have made changes in the settings since the last update...
void load(const std::string &settingsFile)
It initializes the application settings.
static bool isRegularFile(const std::string &path)
Checks if a given path in UTF-8 is a regular file.
Configuration flags for the TerraLib Common Runtime module.
void changed()
This method can be used by clients to inform manually that the internal state has changed...
void setValue(const std::string &key, const std::string &value)
It stores the value according to the key.
std::string m_file
The settings file name.
ApplicationSettings()
Constructor.
Threading policies that can be applied to TerraLib classes that need some synchronization schema...
ObjectLevelLockingPolicy< ::boost::lock_guard< ::boost::recursive_mutex > > LockWrite
~ApplicationSettings()
The destructor will automatically save the settings to a file if one is set.
const boost::property_tree::ptree & getAllSettings() const
It return a reading reference to the internal settings.
std::string getValue(const std::string &key)
It returns the value for a given key or empty.
This policy assures an object-level locking scheme for a derived class.
static bool remove(const std::string &path)
Removes a file or directory from a given path in UTF-8.
ObjectLevelLockingPolicy< ::boost::lock_guard< ::boost::recursive_mutex > > LockRead
boost::property_tree::ptree m_settings
This will keep our settings in memory.
void update()
It updates the application settings.
A class for managing application settings.
