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
