All Implemented Interfaces:

Serializable, Cloneable, Iterable<Object>, Collection<Object>, List<Object>, RandomAccess, BSONObject

Direct Known Subclasses:

BasicDBList

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.

 BSONObject 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
