Examples of net.sf.xbus.base.core.config.Configuration

net.sf.xbus.base.core.config.Configuration
This class reads program parameters from different sources and makes them accessible. The entries of the configuration are organized in a three-level hierarchie:
- The chapter is the top level. Often you will find names of components or classes at this level.
- Every chapter contains one or more sections
- Keys are at the bottom of the hierarchie, beyond the sections.
The Configuration implements the Singleton Design-Pattern.
Up to now, only the Java- Properties can be used as a source for the configuration. Other sources like XML-files or a database are prepared.
