ObjectId (com.sequoiadb:sequoiadb-driver 1.12 API)

java.lang.Object
- org.bson.types.ObjectId

所有已实现的接口:

Serializable, Comparable<ObjectId>
```
public class ObjectId
extends Object
implements Comparable<ObjectId>, Serializable
```
A globally unique identifier for objects.
Consists of 12 bytes, divided as follows:
```
 
 0 1 2 3 4 5 6
     7 8 9 10 11
 time machine
     pid inc
 
 
```

public ObjectId(Date time)
```
  - ObjectId
```
public ObjectId(Date time,
        int inc)
```
  - ObjectId
```
public ObjectId(Date time,
        int machine,
        int inc)
```
  - ObjectId
```
public ObjectId(String s)
```
    Creates a new instance from a string.
    
    参数:
    s - the string to convert
    
    抛出:
    
    IllegalArgumentException - if the string is not a valid id
  - ObjectId
```
public ObjectId(String s,
        boolean babble)
```
  - ObjectId
```
public ObjectId(byte[] b)
```
  - ObjectId
```
public ObjectId(int time,
        int machine,
        int inc)
```
    Creates an ObjectId
    
    参数:
    time - time in seconds
    machine - machine ID
    inc - incremental value
  - ObjectId
```
public ObjectId()
```
    Create a new object id.
- 方法详细资料
  - get
```
public static ObjectId get()
```
    Gets a new object id.
    
    返回:
    the new id
  - isValid
```
public static boolean isValid(String s)
```
    Checks if a string could be an ObjectId.
    
    返回:
    whether the string could be an object id
  - massageToObjectId
```
public static ObjectId massageToObjectId(Object o)
```
    Turn an object into an ObjectId, if possible. Strings will be converted into ObjectIds, if possible, and ObjectIds will be cast and returned. Passing in null returns null.
    
    参数:
    o - the object to convert
    
    返回:
    an ObjectId if it can be massaged, null otherwise
  - hashCode
```
public int hashCode()
```
    覆盖:
    
    hashCode 在类中 Object
  - equals
```
