UnsupportedDurationField (langx-java 1.2.2 API)

java.lang.Object
- com.jn.langx.util.jodatime.DurationField
- - com.jn.langx.util.jodatime.field.UnsupportedDurationField

所有已实现的接口:

Serializable, Comparable<DurationField>
```
public final class UnsupportedDurationField
extends DurationField
implements Serializable
```
A placeholder implementation to use when a duration field is not supported.
UnsupportedDurationField is thread-safe and immutable.
