/**
* Decorator providing additional getters for any Configuration. This extended
* Configuration supports more types:
*
* - {@link java.net.URL}
* - {@link java.util.Locale}
* - {@link java.util.Date}
* - {@link java.util.Calendar}
* - {@link java.awt.Color}
* - {@link java.net.InetAddress}
* - {@link javax.mail.internet.InternetAddress} (requires Javamail in the classpath)
* - {@link java.lang.Enum} (Java 5 enumeration types)
*
*
* Lists and arrays are available for all types.
*
* Example
*
* Configuration file config.properties:
*
* title.color = #0000FF
* remote.host = 192.168.0.53
* default.locales = fr,en,de
* email.contact = [email protected], [email protected]
*
*
* Usage:
*
*
* DataConfiguration config = new DataConfiguration(new PropertiesConfiguration("config.properties"));
*
* // retrieve a property using a specialized getter
* Color color = config.getColor("title.color");
*
* // retrieve a property using a generic getter
* InetAddress host = (InetAddress) config.get(InetAddress.class, "remote.host");
* Locale[] locales = (Locale[]) config.getArray(Locale.class, "default.locales");
* List contacts = config.getList(InternetAddress.class, "email.contact");
*
*
* Dates
*
* Date objects are expected to be formatted with the pattern yyyy-MM-dd HH:mm:ss.
* This default format can be changed by specifying another format in the
* getters, or by putting a date format in the configuration under the key
* org.apache.commons.configuration.format.date.
