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
