load the configuration from the default location . the configuration will be automatically loaded from the default location the first time a value is queried or modified , if it had not been previously loaded . only the first load request will be honored , so if the configuration is to be loaded from a non-default location , load name must be used prior to any other call . the configuration can be loaded only one time . implementations must ignore load requests once a load is already successful , and must return false for each of those ignored requests . concode_field_sep String URL_SAVED concode_elem_sep String FILE_SAVED concode_elem_sep String URL_LOADED concode_elem_sep ConfigurationHandler config concode_elem_sep String FILE_LOADED concode_field_sep boolean save concode_elem_sep boolean save concode_elem_sep void setInteger concode_elem_sep double getDouble concode_elem_sep double getDouble concode_elem_sep int getInteger concode_elem_sep int getInteger concode_elem_sep String getString concode_elem_sep String getString concode_elem_sep void removeListener concode_elem_sep void removeListener concode_elem_sep IConfigurationFactory getFactory concode_elem_sep void setDouble concode_elem_sep ConfigurationKey makeKey concode_elem_sep ConfigurationKey makeKey concode_elem_sep ConfigurationKey makeKey concode_elem_sep ConfigurationKey makeKey concode_elem_sep ConfigurationKey makeKey concode_elem_sep ConfigurationKey makeKey concode_elem_sep void setString concode_elem_sep void removeKey concode_elem_sep ConfigurationHandler getConfigurationHandler concode_elem_sep boolean getBoolean concode_elem_sep boolean getBoolean concode_elem_sep void setBoolean concode_elem_sep void addListener concode_elem_sep void addListener
