Examples of org.bson.BasicBSONObject

org.bson.BasicBSONObject
A simple implementation of DBObject. A DBObject can be created as follows, using this class:
```
 DBObject obj = new BasicBSONObject(); obj.put( "foo", "bar" ); 
```


    private void serveRequest() throws IOException {
      BSONObject reqHead = decoder.readObject(clientSocket.getInputStream());
      BSONObject reqBody = decoder.readObject(clientSocket.getInputStream());


      BSONObject respHead = new BasicBSONObject();
      respHead.put(Constants.SERVICE_METHOD,
          ((String) reqHead.get(Constants.SERVICE_METHOD)).getBytes());
      respHead.put(Constants.SEQ, (UnsignedLong) reqHead.get(Constants.SEQ));
      if (!"Arith.Multiply".equals((String) reqHead.get(Constants.SERVICE_METHOD))) {
        respHead
            .put(Constants.ERROR, ("rpc: can't find method " + (String) reqHead
                .get(Constants.SERVICE_METHOD)).getBytes());
      }


      BSONObject respBody = new BasicBSONObject();
      if (!respHead.containsField(Constants.ERROR)) {

        }
        respBody.put(BsonClientCodec.MAGIC_TAG, A * B);
      }


      clientSocket.getOutputStream().write(encoder.encode(respHead));
