Class SettingsManager

java.lang.Object

com.alee.managers.settings.SettingsManager

public final class SettingsManager
extends java.lang.Object

This manager allows you to quickly and easily save any serializable data into settings files using simple XML format.

You can define settings group file name (they are equal to the SettingsGroup name and should be unique), its location on local or remote drive and each separate property key. Any amount of properties could be stored in each group. Also there are some additional manager settings that allows you to configure SettingsManager to work the way you want it to. The rest of the work is done by the SettingsManager - it decides where, when and how to save the settings files.

Settings data aliasing (see XStream documentation and XmlUtils class) or SettingsGroup file location changes should be done before requesting any of the settings, preferably right at the application startup. Otherwise data might not be properly read and settings will appear empty.
