ServerAddress addr = new ServerAddress(new InetSocketAddress(host, port));
servAddrList.add(addr);
}
MongoOptions options = new MongoOptions();
options.autoConnectRetry = true;
options.connectionsPerHost = Config.intParam(
"mongo.connectionsPerHost", 1200);

What are you looking for in my opinion is readPreference : http://docs.mongodb.org/manual/applications/replication/#replica-set-read-preference

In the api (http://api.mongodb.org/java/2.10.1/com/mongodb/ReadPreference.html) documentation there is an isSlaveOk() method : http://api.mongodb.org/java/2.10.1/com/mongodb/ReadPreference.html#isSlaveOk()

See this question: How to perform read operations from primary only

There is the answer for setting read preference 

mongo.setReadPreference(ReadPreference.primary());

and your answer is to get read preference:

mongo.getReadPreference().isSlaveOk();

Unfortunately these features do not exist in versions after 2.4.
