Hi All,  
I am using JAVA REST API to create index and add data to the index.  
Below is the code I am using:

```auto
Map<String, Object> dataMap = new HashMap<String, Object>();
dataMap.put("appname", app);
dataMap.put("version", version);
.
.
.
IndexRequest indexRequest = new IndexRequest("appindex").source(dataMap);
IndexResponse indexResponse = client.index(indexRequest, RequestOptions.DEFAULT);

```

This piece of code works perfectly to create index and add the the dataMap to the index.

My requirement is that I need to iterate over a list of object and add datas to dataMap then add the dataMap to the index.  
For instance -

```auto
Iterate over a object(){
dataMap.add("key", Value)
dataMap.add("Key", Value)
Add data to index
} move to next iteration.

```

Is this kind of operation possible using JAVA REST API?
