public class ContextPrefs

extends Prefs

Preferences is used to get application configuration parameters. Preferences supplied several methods to handle type conversion of the parameter requested. A default parameter may also be supplied for cases where the parameter requested is not found or there is some other error.

Missing parameters and type conversion failures will throw a PreferencesException except where a default is supplied in which case the default will be returned.

Call getInstance() to get an instance of Preferences.

Example:

  String myValue = Preferences.getInstance().getValueAsString("user.email.address");
  

This class requires a Context to be bound to the ApplicationCtx called "preference".
