AbstractInstant (langx-java 2.2.3 API)

java.lang.Object
- com.jn.langx.util.jodatime.base.AbstractInstant

所有已实现的接口:

ReadableInstant, Comparable<ReadableInstant>

直接已知子类:

AbstractDateTime, Instant
```
public abstract class AbstractInstant
extends Object
implements ReadableInstant
```
AbstractInstant provides the common behaviour for instant classes.
This class has no concept of a chronology, all methods work on the millisecond instant.
This class should generally not be used directly by API users. The ReadableInstant interface should be used when different kinds of date/time objects are to be referenced.
Whenever you want to implement ReadableInstant you should extend this class.
AbstractInstant itself is thread-safe and immutable, but subclasses may be mutable and not thread-safe.

```
protected AbstractInstant()
```
    Constructor.
- 方法详细资料
  - getZone
```
public DateTimeZone getZone()
```
    Gets the time zone of the instant from the chronology.
    
    指定者:
    
    getZone 在接口中 ReadableInstant
    
    返回:

  - get
```
public int get(DateTimeFieldType type)
```
    Get the value of one of the fields of a datetime using the chronology of the instant.
    This method uses the chronology of the instant to obtain the value. For example:
```
 DateTime dt = new DateTime();
 int year = dt.get(DateTimeFieldType.year());
 
```
    指定者:
    
    get 在接口中 ReadableInstant
    
    参数:

    返回:
    
    the value of that field
    
    抛出:
    
    IllegalArgumentException - if the field type is null
  - isSupported
```
public boolean isSupported(DateTimeFieldType type)
```
    Checks if the field type specified is supported by this instant and chronology. This can be used to avoid exceptions in get(DateTimeFieldType).
    
    指定者:
    
    isSupported 在接口中 ReadableInstant
    
    参数:
    
    type - a field type, usually obtained from DateTimeFieldType

```
    参数:
    
    field - the DateTimeField to use, not null
