For example, URLFrontierAdapter, URLFrontierConfiguration.

It can be quite time consuming trying to find out what to do by trawling through source code.

We are open for pull request improving the documentation.

If you take the example from README, it basically boils down to switch the FrontierConfiguration to choose the related frontier implementation:

        FrontierConfiguration frontierConfiguration = new SleepycatFrontierConfiguration(config);
        // OR use
        FrontierConfiguration frontierConfiguration = new HSQLDBFrontierConfiguration(config, 10);
       // OR use
       FrontierConfiguration frontierConfiguration = new URLFrontierConfiguration(config, 10, "localhost", 7071);

URLFrontierAdapter is an implementation detail ;-)
