## Class DataConfiguration

- java.lang.Object
- - org.apache.commons.configuration2.event.BaseEventSource
  - - org.apache.commons.configuration2.AbstractConfiguration
    - - org.apache.commons.configuration2.DataConfiguration

- All Implemented Interfaces:
    Configuration, EventSource, ImmutableConfiguration, SynchronizerSupport

      public class DataConfiguration
      extends AbstractConfiguration

  Decorator providing additional getters for any Configuration. This extended Configuration supports more types:
  - `URL`
  - `Locale`
  - `Date`
  - `Calendar`
  - `Color`
  - `InetAddress`
  - `javax.mail.internet.InternetAddress` (requires Javamail in the classpath)
  - `Enum` (Java 5 enumeration types)
  Lists and arrays are available for all types.
  Note that this class is only a thin wrapper over functionality already provided by `AbstractConfiguration`. Basically, the generic `get()`, and `getCollection()` methods are used to actually perform data conversions.

  Example

  Configuration file `config.properties`:

       title.color = #0000FF
       remote.host = 192.168.0.53
       default.locales = fr,en,de
       email.contact = ebourg@apache.org, tester@test.org

  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`. Alternatively, the date format can also be specified via the `ConversionHandler` used by a configuration instance:

       DefaultConversionHandler handler = new DefaultConversionHandler();
       handler.setDateFormat("mm/dd/yyyy");
       config.setConversionHandler(handler);

  Since:
    1.1
