所有已实现的接口:

public class BasicBSONList
extends ArrayList<Object>
implements BSONObject

Utility class to allow array DBObjects to be created.

Note: MongoDB will also create arrays from java.util.Lists.

 DBObject obj = new BasicBSONList();
 obj.put("0", value1);
 obj.put("4", value2);
 obj.put(2, value3);
 

This simulates the array [ value1, null, value3, null, value2 ] by creating the DBObject { "0" : value1, "1" : null, "2" : value3, "3" : null, "4" : value2 } .

BasicBSONList only supports numeric keys. Passing strings that cannot be converted to ints will cause an IllegalArgumentException.

 BasicBSONList list = new BasicBSONList();
 list.put("1", "bar"); // ok
 list.put("1E1", "bar"); // throws exception

BasicBSONList

public BasicBSONList()

方法详细资料

put

public Object put(String key,
         Object v)

指定者:

put 在接口中 BSONObject

参数:

key - the index at which to insert the value

v - the value to insert

返回:

the value

抛出:

IllegalArgumentException - if key cannot be parsed into an int

put

public Object put(int key,
         Object v)

Puts a value at an index. This will fill any unset indexes less than index with null.

参数:

key - the index at which to insert the value

v - the value to insert

返回:

the value

putAll

public void putAll(Map m)

从接口复制的说明: BSONObject
