public interface IterableConfigurationPropertySource extends ConfigurationPropertySource, Iterable<ConfigurationPropertyName>
ConfigurationPropertySource with a fully Iterable set of entries.
Implementations of this interface must be able to iterate over all
contained configuration properties. Any non-null result from
ConfigurationPropertySource.getConfigurationProperty(ConfigurationPropertyName) must also have an
equivalent entry in the iterator.ConfigurationPropertyName,
