Documentation & Examples¶ ↑

To begin reviewing the available methods and examples, peruse the README.rodc file, or begin by looking at documentation for the CloudDB::Connection class.

The CloudDB class is the base class. Not much of note aside from housekeeping happens here. To create a new CloudDB connection, use the CloudDB::Connection.new method.
