afReflux::Preferences

@Js

(Service) - Loads / saves and maintains a cache of preference objects. Instances are cached until the backing file is updated / modified.

Because Reflux is application centric, preference files are not associated with pods, but with the application name supplied at startup:

%FAN_HOME%/etc/<app-name>/xxx.fog

Note that Preference instances must be serializable and have an it-block ctor:

new make(|This| f) { f(this) }

findFile

Source

abstract File? findFile(Str name)

Finds the named file in the applications etc dir. If such a file does not exist, a file in the workDir is returned.

loadPrefs

Source

abstract Obj loadPrefs(Type prefsType, Str? name := null)

Returns an instance of the given preferences object.

preferences.loadPrefs(MyPrefs#, "myPrefs.fog")

savePrefs

Source

abstract Void savePrefs(Obj prefs, Str? name := null)

Saves the given preference instance.

preferences.savePrefs(myPrefs, "myPrefs.fog")

updated

Source

abstract Bool updated(Type prefsType, Str? name := null)

Returns true if the preferences file has been updated since it was last read.
