Class SettingsManager

java.lang.Object
  com.jstatcom.project.SettingsManager

public final class SettingsManager
extends java.lang.Object

Singleton class that manages storing and retrieving of settings that should be kept permanently between two program runs. The methods saveSettings and restoreSettings are automatically being invoked from the TopFrame class when the application is quit or started, respectively.

This class also loads the last state from a special project file. This way the application always restores the project settings that were used when it was quit.

The last state and the settings are store in two different XML files in the users home directory under a name starting with a ".", followed by the title of the application, and the suffix "_settings" and "_laststate", respectively.
