## Interface ConfigurationDecoder

-     public interface ConfigurationDecoder

  An interface for decoding encoded values from a configuration source.

  Using this interface it is possible to store encoded or encrypted values in a configuration file. An implementing object can be assigned to a configuration object. The `getEncodedString()` method of the `ImmutableConfiguration` interface makes use of this instance to decode the value read from the configuration file before it is passed to the caller.

  By providing custom implementations of this interface an application can add support for different kinds of encoded strings in configuration files.

  Since:
    2.0
