所有已实现的接口:

ReadablePartial, Comparable<ReadablePartial>

BaseLocal, BasePartial, Partial
```
public abstract class AbstractPartial
extends Object
implements ReadablePartial, Comparable<ReadablePartial>
```
AbstractPartial provides a standard base implementation of most methods in the ReadablePartial interface.
Calculations on are performed using a Chronology. This chronology is set to be in the UTC time zone for all calculations.
The methods on this class use ReadablePartial.size(), getField(int, Chronology) and ReadablePartial.getValue(int) to calculate their results. Subclasses may have a better implementation.
AbstractPartial allows subclasses may be mutable and not thread-safe.

```
    Is this partial the same as the specified partial.
    The fields are compared in order, from largest to smallest. If all fields are equal, the result is true.
    You may not pass null into this method. This is because you need a time zone to accurately determine the current date.
    
    参数:
    
    partial - a partial to check against, must not be null
    
    返回:
    
    true if this date is the same as the date passed in
