public interface IterableConfigurationPropertySource extends ConfigurationPropertySource, java.lang.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
.Modifier and Type | Method and Description |

default ConfigurationPropertyState |
containsDescendantOf(ConfigurationPropertyName name)
Returns if the source contains any descendants of the specified name.

default IterableConfigurationPropertySource |
filter(java.util.function.Predicate<ConfigurationPropertyName> filter)
Return a filtered variant of this source, containing only names that match the
given
Predicate . |
default java.util.Iterator<ConfigurationPropertyName> |
iterator()
Return an iterator for the
names managed by this
source. |
java.util.stream.Stream<ConfigurationPropertyName> |
stream()
