/**
 * API to interact with the {@link TS3Query} synchronously.
 * <p>
 * This class is used to easily interact with a {@link TS3Query}. It constructs commands,
 * sends them to the TeamSpeak3 server, processes the response and returns the result.
 * </p><p>
 * All methods in this class are synchronous, so they will block until the response arrives.
 * Calls to this API will usually take about 50 milliseconds to complete (plus ping),
 * but delays can range up to 4 seconds.
 * If a command takes longer than 4 seconds to complete, a {@link TS3ConnectionFailedException}
 * will be thrown.
 * </p><p>
 * You won't be able to execute most commands while you're not logged in due to missing permissions.
 * Make sure to either pass your login credentials to the {@link TS3Config} object when
 * creating the {@code TS3Query} or to call {@link #login(String, String)} to log in.
 * </p><p>
 * After that, most commands also require you to select a {@linkplain VirtualServer virtual server}.
 * To do so, call either {@link #selectVirtualServerByPort(int)} or {@link #selectVirtualServerById(int)}.
 * </p><p>
 * Be aware that many methods in this class will return {@code null} or {@code -1} if a command fails.
 * </p>
