/**
 * The Cloud Spanner JDBC driver supports a number of client side statements that are interpreted by
 * the driver and that can modify the current state of a connection, or report the current state of
 * a connection. Each of the methods in this interface correspond with one such client side
 * statement.
 *
 * The methods in this interface are called by the different {@link ClientSideStatement}s. These
 * method calls are then forwarded into the appropriate method of a {@link Connection} instance.
 *
 * The client side statements are defined in the ClientSideStatements.json file.
