DelegatedDurationField (langx-java 1.2.2 API)

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

所有已实现的接口:

Serializable, Comparable<DurationField>
```
public class DelegatedDurationField
extends DurationField
implements Serializable
```
DelegatedDurationField delegates each method call to the duration field it wraps.
DelegatedDurationField is thread-safe and immutable, and its subclasses must be as well.

  - getUnitMillis
```
public long getUnitMillis()
```
    从类复制的说明: DurationField
    
    Returns the amount of milliseconds per unit value of this field. For example, if this field represents "seconds", then this returns the milliseconds in one second.
    For imprecise fields, the unit size is variable, and so this method returns a suitable average value.
    
    指定者:
    
    getUnitMillis 在类中 DurationField
    
    返回:
    
    the unit size of this field, in milliseconds
