org.openbp.common.setting.SettingResolver

The setting resolver manages a chain of setting providers. The providers may retrieve or save settings. The setting resolver will access the registered setting providers in order to resolve (i. e. retrieve or store) the setting.
A setting provider may be e. g. a provider that store settings in a property file, but also a provider that may store them in a database under the name of the current user. When a provider registers with the resolver, it can be assigned a priority. The priority will determine the order in which the resolver will ask the providers if they can resolve the setting. A setting is identified by its name, which can include sub setting specifications (sections), which are separated by the '.' character, e. g. "section1.section2.name".
The setting name may optionally include the name of the setting provider, e. g. "user:section1.section2.name". Some setting providers may save the settings automatically if one of the set methods is called, whereas others may cache the settings and save them to the persistent storage after the {@link #saveSettings} method has been called. @author Heiko Erhardt
