Examples of org.apache.openjpa.lib.util.Options

org.apache.openjpa.lib.util.Options
A specialization of the {@link Properties} map type with the addedabilities to read application options from the command line and to use bean patterns to set an object's properties via command-line the stored mappings. A typical use pattern for this class is to construct a new instance in the main method, then call {@link #setFromCmdLine} with thegiven args. Next, an instanceof the class being invoked is created, and {@link #setInto} is called with that instance as a parameter. With thispattern, the user can configure any bean properties of the class, or even properties of classes reachable from the class, through the command line. @author Abe White @nojavadoc
