A library for settings and parameterization of objects. Key features are support for data types, help for settings and parameters, annotations for ease of use. Settings and parameters both are Clonable and Serializable. More features for settings such as parsing a settingsfile, being observable, readonliness, caching etc. are available. The library contains javacc generated parsers for syntax support for properties, multi valued properties, parameterized objects and multi valued parameters.
The newest version!
