The API version used by this library in all tests and documentation

Initializes networking, connects with the default fdb.cluster file, and opens the database.

Returns: - a CompletableFuture that will be set to a FoundationDB Database

Throws: FDBException

Returns a set of options that can be set on a the FoundationDB API. Generally, these options to the top level of the API affect the networking engine and therefore must be set before the network engine is started. The network is started by calls to startNetwork() and implicitly by calls to open() and createCluster() (and their respective variants).

Select the version for the client API. An exception will be thrown if the requested version is not supported by this implementation of the API. As only one version can be selected for the lifetime of the JVM, the result of a successful call to this method is always the same instance of a FDB object.

Warning: When using the multi-version client API, setting an API version that is not supported by a particular client library will prevent that client from being used to connect to the cluster. In particular, you should not advance the API version of your application after upgrading your client until the cluster has also been upgraded.

Enables or disables the stderr warning that is printed whenever an object with FoundationDB native resources is garbage collected without being closed. By default, this feature is enabled.

Initializes networking. Can only be called once. This version of startNetwork() will create a new thread and execute the networking event loop on that thread. This method is called upon Database or Cluster creation by default if the network has not yet been started. If one wishes to control what thread the network runs on, one should use the version of startNetwork() that takes an Executor.

Configuration of the networking engine can be achieved through calls to the methods in NetworkOptions.

Throws: - java.lang.IllegalStateException - if the network has already been stopped - FDBException

See Also: NetworkOptions.

Stops the FoundationDB networking engine. This can be called only once – the network cannot be restarted after this call. This call blocks for the completion of the FoundationDB networking engine.

Throws: - FDBException - on errors while stopping the network.
