Constructor Detail

FileBasedConfig

public FileBasedConfig(File cfgLocation,
                       FS fs)

Create a configuration with no default fallback.

Parameters:

cfgLocation - the location of the configuration file on the file system

fs - the file system abstraction which will be necessary to perform certain file system operations.

FileBasedConfig

public FileBasedConfig(Config base,
                       File cfgLocation,
                       FS fs)

The constructor

Parameters:

base - the base configuration file

cfgLocation - the location of the configuration file on the file system

fs - the file system abstraction which will be necessary to perform certain file system operations.

Method Detail

notifyUponTransientChanges

protected boolean notifyUponTransientChanges()

Description copied from class: Config

Determine whether to issue change events for transient changes.

If true is returned (which is the default behavior), Config.fireConfigChangedEvent() will be called upon each change.

Subclasses that override this to return false are responsible for issuing Config.fireConfigChangedEvent() calls themselves.

Overrides:

notifyUponTransientChanges in class Config

Returns:

getFile

public final File getFile()

Returns:

location of the configuration file on disk

load

public void load()
          throws IOException,
                 ConfigInvalidException

Load the configuration as a Git text style configuration file.

If the file does not exist, this configuration is cleared, and thus behaves the same as though the file exists, but is empty.

Specified by:

load in class StoredConfig

Throws:

IOException - the file could not be read (but does exist).

ConfigInvalidException - the file is not a properly formatted configuration file.

save

public void save()
          throws IOException

Save the configuration as a Git text style configuration file.

Warning: Although this method uses the traditional Git file locking approach to protect against concurrent writes of the configuration file, it does not ensure that the file has not been modified since the last read, which means updates performed by other objects accessing the same backing file may be lost.

Specified by:

save in class StoredConfig

Throws:

IOException - the file could not be written.

clear

public void clear()

Description copied from class: Config

Clear the configuration file

Overrides:

clear in class StoredConfig

toString

public String toString()

Overrides:

toString in class Object

isOutdated

public boolean isOutdated()

Returns:

returns true if the currently loaded configuration file is older than the file on disk
