# 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)
- `jakarta.mail.internet.InternetAddress` (requires Javamail 2.+ 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 = dev@test.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);
